Guitar

The guitar is a fretted musical instrument that usually has six strings.[1] It is typically played with both hands by strumming or plucking the strings with either a guitar pick or the finger(s)/fingernails of one hand, while simultaneously fretting (pressing the strings against the frets) with the fingers of the other hand. The sound of the vibrating strings is projected either acoustically, by means of the hollow chamber of the guitar (for an acoustic guitar), or through an electrical amplifier and a speaker.

The guitar is a type of chordophone, traditionally constructed from wood and strung with either gut, nylon or steel strings and distinguished from other chordophones by its construction and tuning. The modern guitar was preceded by the gittern, the vihuela, the four-course Renaissance guitar, and the five-course baroque guitar, all of which contributed to the development of the modern six-string instrument.

There are three main types of modern acoustic guitar: the classical guitar (Spanish guitar/nylon-string guitar), the steel-string acoustic guitar, and the archtop guitar, which is sometimes called a "jazz guitar". The tone of an acoustic guitar is produced by the strings' vibration, amplified by the hollow body of the guitar, which acts as a resonating chamber. The classical guitar is often played as a solo instrument using a comprehensive finger-picking technique where each string is plucked individually by the player's fingers, as opposed to being strummed. The term "finger-picking" can also refer to a specific tradition of folk, blues, bluegrass, and country guitar playing in the United States. The acoustic bass guitar is a low-pitched instrument that is one octave below a regular guitar.

Electric guitars, introduced in the 1930s, use an amplifier and a loudspeaker that both makes the sound of the instrument loud enough for the performers and audience to hear, and, given that it produces an electric signal when played, that can electronically manipulate and shape the tone using an equalizer (e.g., bass and treble tone controls) and a huge variety of electronic effects units, the most commonly used ones being distortion (or "overdrive") and reverb. Early amplified guitars employed a hollow body, but solid wood guitars began to dominate during the 1960s and 1970s, as they are less prone to unwanted acoustic feedback "howls". As with acoustic guitars, there are a number of types of electric guitars, including hollowbody guitars, archtop guitars (used in jazz guitar, blues and rockabilly) and solid-body guitars, which are widely used in rock music.

The loud, amplified sound and sonic power of the electric guitar played through a guitar amp has played a key role in the development of blues and rock music, both as an accompaniment instrument (playing riffs and chords) and performing guitar solos, and in many rock subgenres, notably heavy metal music and punk rock. The electric guitar has had a major influence on popular culture. The guitar is used in a wide variety of musical genres worldwide. It is recognized as a primary instrument in genres such as blues, bluegrass, country, flamenco, folk, jazz, jota, mariachi, metal, punk, reggae, rock, soul, and many forms of pop.

History

Before the development of the electric guitar and the use of synthetic materials, a guitar was defined as being an instrument having "a long, fretted neck, flat wooden soundboard, ribs, and a flat back, most often with incurved sides."[2] The term is used to refer to a number of chordophones that were developed and used across Europe, beginning in the 12th century and, later, in the Americas.[3] A 3,300-year-old stone carving of a Hittite bard playing a stringed instrument is the oldest iconographic representation of a chordophone and clay plaques from Babylonia show people playing an instrument that has a strong resemblance to the guitar, indicating a possible Babylonian origin for the guitar.[2]

The modern word guitar, and its antecedents, has been applied to a wide variety of chordophones since classical times and as such causes confusion. The English word guitar, the German Gitarre, and the French guitare were all adopted from the Spanish guitarra, which comes from the Andalusian Arabic قيثارة (qīthārah)[4] and the Latin cithara, which in turn came from the Ancient Greek κιθάρα (kithara).[A] which comes from Persian word "sihtar." This pattern of naming is also visible in Setar, Dutar and Sitar. The word "tar" at the end of all of these words is a Persian word that means "string".[6]

Many influences are cited as antecedents to the modern guitar. Although the development of the earliest "guitars" is lost in the history of medieval Spain, two instruments are commonly cited as their most influential predecessors, the European lute and its cousin, the four-string oud; the latter was brought to Iberia by the Moors in the 8th century.[7]

At least two instruments called "guitars" were in use in Spain by 1200: the guitarra latina (Latin guitar) and the so-called guitarra morisca (Moorish guitar). The guitarra morisca had a rounded back, wide fingerboard, and several sound holes. The guitarra Latina had a single sound hole and a narrower neck. By the 14th century the qualifiers "moresca" or "morisca" and "latina" had been dropped, and these two cordophones were simply referred to as guitars.[8]

The Spanish vihuela, called in Italian the "viola da mano", a guitar-like instrument of the 15th and 16th centuries, is widely considered to have been the single most important influence in the development of the baroque guitar. It had six courses (usually), lute-like tuning in fourths and a guitar-like body, although early representations reveal an instrument with a sharply cut waist. It was also larger than the contemporary four-course guitars. By the 16th century, the vihuela's construction had more in common with the modern guitar, with its curved one-piece ribs, than with the viols, and more like a larger version of the contemporary four-course guitars. The vihuela enjoyed only a relatively short period of popularity in Spain and Italy during an era dominated elsewhere in Europe by the lute; the last surviving published music for the instrument appeared in 1576.[9]

Meanwhile, the five-course baroque guitar, which was documented in Spain from the middle of the 16th century, enjoyed popularity, especially in Spain, Italy and France from the late 16th century to the mid-18th century.[B][C] In Portugal, the word viola referred to the guitar, as guitarra meant the "Portuguese guitar", a variety of cittern.

Finally, circa 1850, the form and structure of the modern Guitar is credited to Spanish guitar maker Antonio Torres Jurado, who increased the size of the guitar body, altered its proportions, and invented the breakthrough fan-braced pattern. Bracing, which refers to the internal pattern of wood reinforcements used to secure the guitar's top and back and prevent the instrument from collapsing under tension, is an important factor in how the guitar sounds. Torres' design greatly improved the volume, tone, and projection of the instrument, and it has remained essentially unchanged since.

Types

Guitars can be divided into two broad categories, acoustic and electric guitars. Within each of these categories, there are also further sub-categories. For example, an electric guitar can be purchased in a six-string model (the most common model) or in seven or 12-string models.

Acoustic

Acoustic guitars form several notable subcategories within the acoustic guitar group: classical and flamenco guitars; steel-string guitars, which include the flat-topped, or "folk", guitar; twelve-string guitars; and the arched-top guitar. The acoustic guitar group also includes unamplified guitars designed to play in different registers, such as the acoustic bass guitar, which has a similar tuning to that of the electric bass guitar.

Renaissance and Baroque

Renaissance and Baroque guitars are the ancestors of the modern classical and flamenco guitar. They are substantially smaller, more delicate in construction, and generate less volume. The strings are paired in courses as in a modern 12-string guitar, but they only have four or five courses of strings rather than six single strings normally used now. They were more often used as rhythm instruments in ensembles than as solo instruments, and can often be seen in that role in early music performances. (Gaspar Sanz's Instrucción de Música sobre la Guitarra Española of 1674 contains his whole output for the solo guitar.)[10] Renaissance and Baroque guitars are easily distinguished, because the Renaissance guitar is very plain and the Baroque guitar is very ornate, with ivory or wood inlays all over the neck and body, and a paper-cutout inverted "wedding cake" inside the hole.

Classical

Classical guitars, also known as "Spanish" guitars, [11] are typically strung with nylon strings, plucked with the fingers, played in a seated position and are used to play a diversity of musical styles including classical music. The classical guitar's wide, flat neck allows the musician to play scales, arpeggios, and certain chord forms more easily and with less adjacent string interference than on other styles of guitar. Flamenco guitars are very similar in construction, but they are associated with a more percussive tone. In Portugal, the same instrument is often used with steel strings particularly in its role within fado music. The guitar is called viola, or violão in Brazil, where it is often used with an extra seventh string by choro musicians to provide extra bass support.

In Mexico, the popular mariachi band includes a range of guitars, from the small requinto to the guitarrón, a guitar larger than a cello, which is tuned in the bass register. In Colombia, the traditional quartet includes a range of instruments too, from the small bandola (sometimes known as the Deleuze-Guattari, for use when traveling or in confined rooms or spaces), to the slightly larger tiple, to the full-sized classical guitar. The requinto also appears in other Latin-American countries as a complementary member of the guitar family, with its smaller size and scale, permitting more projection for the playing of single-lined melodies. Modern dimensions of the classical instrument were established by the Spaniard Antonio de Torres Jurado (1817–1892).[12]

Flat-top

Flat-top or steel-string guitars are similar to the classical guitar, however, within the varied sizes of the steel-stringed guitar the body size is usually significantly larger than a classical guitar, and has a narrower, reinforced neck and stronger structural design. The robust X-bracing typical of the steel-string was developed in the 1840s by German-American luthiers, of whom Christian Friedrich "C. F." Martin is the best known. Originally used on gut-strung instruments, the strength of the system allowed the guitar to withstand the additional tension of steel strings when this fortunate combination arose in the early 20th century. The steel strings produce a brighter tone, and according to many players, a louder sound. The acoustic guitar is used in many kinds of music including folk, country, bluegrass, pop, jazz, and blues. Many variations are possible from the roughly classical-sized OO and Parlour to the large Dreadnought (the most commonly available type) and Jumbo. Ovation makes a modern variation, with a rounded back/side assembly molded from artificial materials.

Archtop

Archtop guitars are steel-string instruments in which the top (and often the back) of the instrument are carved, from a solid billet, into a curved, rather than a flat, shape. This violin-like construction is usually credited to the American Orville Gibson. Lloyd Loar of the Gibson Mandolin-Guitar Mfg. Co introduced the violin-inspired "F"-shaped hole design now usually associated with archtop guitars, after designing a style of mandolin of the same type. The typical archtop guitar has a large, deep, hollow body whose form is much like that of a mandolin or a violin-family instrument. Nowadays, most archtops are equipped with magnetic pickups, and they are therefore both acoustic and electric. F-hole archtop guitars were immediately adopted, upon their release, by both jazz and country musicians, and have remained particularly popular in jazz music, usually with flatwound strings.

Resonator, resophonic or Dobros

JMT8stringguitar

All three principal types of resonator guitars were invented by the Slovak-American John Dopyera (1893–1988) for the National and Dobro (Dopyera Brothers) companies. Similar to the flat top guitar in appearance, but with a body that may be made of brass, nickel-silver, or steel as well as wood, the sound of the resonator guitar is produced by one or more aluminum resonator cones mounted in the middle of the top. The physical principle of the guitar is therefore similar to the loudspeaker.

The original purpose of the resonator was to produce a very loud sound; this purpose has been largely superseded by electrical amplification, but the resonator guitar is still played because of its distinctive tone. Resonator guitars may have either one or three resonator cones. The method of transmitting sound resonance to the cone is either a "biscuit" bridge, made of a small piece of hardwood at the vertex of the cone (Nationals), or a "spider" bridge, made of metal and mounted around the rim of the (inverted) cone (Dobros). Three-cone resonators always use a specialized metal bridge. The type of resonator guitar with a neck with a square cross-section—called "square neck" or "Hawaiian"—is usually played face up, on the lap of the seated player, and often with a metal or glass slide. The round neck resonator guitars are normally played in the same fashion as other guitars, although slides are also often used, especially in blues.

Twelve-string

The twelve-string guitar usually has steel strings, and it is widely used in folk music, blues, and rock and roll. Rather than having only six strings, the 12-string guitar has six courses made up of two strings each, like a mandolin or lute. The highest two courses are tuned in unison, while the others are tuned in octaves. The 12-string guitar is also made in electric forms. The chime-like sound of the 12-string electric guitar was the basis of jangle pop.

Acoustic bass

The acoustic bass guitar is a bass instrument with a hollow wooden body similar to, though usually somewhat larger than, that of a 6-string acoustic guitar. Like the traditional electric bass guitar and the double bass, the acoustic bass guitar commonly has four strings, which are normally tuned E-A-D-G, an octave below the lowest four strings of the 6-string guitar, which is the same tuning pitch as an electric bass guitar. It can, more rarely, be found with 5 or 6 strings, which provides a wider range of notes to be played with less movement up and down the neck.

Electric

Electric guitars can have solid, semi-hollow, or hollow bodies; solid bodies produce little sound without amplification. Electromagnetic pickups, and sometimes piezoelectric pickups, convert the vibration of the steel strings into signals, which are fed to an amplifier through a patch cable or radio transmitter. The sound is frequently modified by other electronic devices (effects units) or the natural distortion of valves (vacuum tubes) or the pre-amp in the amplifier. There are two main types of magnetic pickups, single- and double-coil (or humbucker), each of which can be passive or active. The electric guitar is used extensively in jazz, blues, R & B, and rock and roll. The first successful magnetic pickup for a guitar was invented by George Beauchamp, and incorporated into the 1931 Ro-Pat-In (later Rickenbacker) "Frying Pan" lap steel; other manufacturers, notably Gibson, soon began to install pickups in archtop models. After World War II the completely solid-body electric was popularized by Gibson in collaboration with Les Paul, and independently by Leo Fender of Fender Music. The lower fretboard action (the height of the strings from the fingerboard), lighter (thinner) strings, and its electrical amplification lend the electric guitar to techniques less frequently used on acoustic guitars. These include tapping, extensive use of legato through pull-offs and hammer-ons (also known as slurs), pinch harmonics, volume swells, and use of a tremolo arm or effects pedals.

Some electric guitar models feature piezoelectric pickups, which function as transducers to provide a sound closer to that of an acoustic guitar with the flip of a switch or knob, rather than switching guitars. Those that combine piezoelectric pickups and magnetic pickups are sometimes known as hybrid guitars.[13]

Hybrids of acoustic and electric guitars are also common. There are also more exotic varieties, such as guitars with two, three,[14] or rarely four necks, all manner of alternate string arrangements, fretless fingerboards (used almost exclusively on bass guitars, meant to emulate the sound of a stand-up bass), 5.1 surround guitar, and such.

Seven-string and eight-string

Solid body seven-string guitars were popularized in the 1980s and 1990s. Other artists go a step further, by using an eight-string guitar with two extra low strings. Although the most common seven-string has a low B string, Roger McGuinn (of The Byrds and Rickenbacker) uses an octave G string paired with the regular G string as on a 12-string guitar, allowing him to incorporate chiming 12-string elements in standard six-string playing. In 1982 Uli Jon Roth developed the "Sky Guitar", with a vastly extended number of frets, which was the first guitar to venture into the upper registers of the violin. Roth's seven-string and "Mighty Wing" guitar features a wider octave range.

The bass guitar (also called an "electric bass", or simply a "bass") is similar in appearance and construction to an electric guitar, but with a longer neck and scale length, and four to six strings. The four-string bass, by far the most common, is usually tuned the same as the double bass, which corresponds to pitches one octave lower than the four lowest pitched strings of a guitar (E, A, D, and G). (The bass guitar is a transposing instrument, as it is notated in bass clef an octave higher than it sounds (as is the double bass) to avoid excessive ledger lines.) Like the electric guitar, the bass guitar has pickups and it is plugged into an amplifier and speaker for live performances.

Handedness

Modern guitars can be constructed to suit both left- and right-handed players. Normally, the dominant hand (in most people, the right hand) is used to pluck or strum the strings. This is similar to the convention of the violin family of instruments where the right hand controls the bow.

Left-handed players sometimes choose an opposite-handed (mirror) instrument, although some play in a standard-handed manner, others play a standard-handed guitar reversed, and still others (for example Jimi Hendrix) played a standard-handed guitar strung in reverse. This last configuration differs from a true opposite handed guitar in that the saddle is normally angled in such a way that the bass strings are slightly longer than the treble strings to improve intonation. Reversing the strings, therefore, reverses the relative orientation of the saddle, adversely affecting intonation, although in Hendrix's case, this is believed to have been an important element in his unique sound.

Components

Head

The headstock is located at the end of the guitar neck farthest from the body. It is fitted with machine heads that adjust the tension of the strings, which in turn affects the pitch. The traditional tuner layout is "3+3", in which each side of the headstock has three tuners (such as on Gibson Les Pauls). In this layout, the headstocks are commonly symmetrical. Many guitars feature other layouts, including six-in-line tuners (featured on Fender Stratocasters) or even "4+2" (e.g. Ernie Ball Music Man). Some guitars (such as Steinbergers) do not have headstocks at all, in which case the tuning machines are located elsewhere, either on the body or the bridge.

The nut is a small strip of bone, plastic, brass, corian, graphite, stainless steel, or other medium-hard material, at the joint where the headstock meets the fretboard. Its grooves guide the strings onto the fretboard, giving consistent lateral string placement. It is one of the endpoints of the strings' vibrating length. It must be accurately cut, or it can contribute to tuning problems due to string slippage or string buzz. To reduce string friction in the nut, which can adversely affect tuning stability, some guitarists fit a roller nut. Some instruments use a zero fret just in front of the nut. In this case the nut is used only for lateral alignment of the strings, the string height and length being dictated by the zero fret.

Neck

A guitar's frets, fretboard, tuners, headstock, and truss rod, all attached to a long wooden extension, collectively constitute its neck. The wood used to make the fretboard usually differs from the wood in the rest of the neck. The bending stress on the neck is considerable, particularly when heavier gauge strings are used (see Tuning), and the ability of the neck to resist bending (see Truss rod) is important to the guitar's ability to hold a constant pitch during tuning or when strings are fretted. The rigidity of the neck with respect to the body of the guitar is one determinant of a good instrument versus a poor-quality one.

The shape of the neck (from a cross-sectional perspective) can also vary, from a gentle "C" curve to a more pronounced "V" curve. There are many different types of neck profiles available, giving the guitarist many options. Some aspects to consider in a guitar neck may be the overall width of the fretboard, scale (distance between the frets), the neck wood, the type of neck construction (for example, the neck may be glued in or bolted on), and the shape (profile) of the back of the neck. Other types of material used to make guitar necks are graphite (Steinberger guitars), aluminum (Kramer Guitars, Travis Bean and Veleno guitars), or carbon fiber (Modulus Guitars and ThreeGuitars). Double neck electric guitars have two necks, allowing the musician to quickly switch between guitar sounds.

The neck joint or heel is the point at which the neck is either bolted or glued to the body of the guitar. Almost all acoustic steel-string guitars, with the primary exception of Taylors, have glued (otherwise known as set) necks, while electric guitars are constructed using both types. Most classical guitars have a neck and headblock carved from one piece of wood, known as a "Spanish heel." Commonly used set neck joints include mortise and tenon joints (such as those used by C. F. Martin & Co.), dovetail joints (also used by C. F. Martin on the D-28 and similar models) and Spanish heel neck joints, which are named after the shoe they resemble and commonly found in classical guitars. All three types offer stability.

Bolt-on necks, though they are historically associated with cheaper instruments, do offer greater flexibility in the guitar's set-up, and allow easier access for neck joint maintenance and repairs. Another type of neck, only available for solid body electric guitars, is the neck-through-body construction. These are designed so that everything from the machine heads down to the bridge are located on the same piece of wood. The sides (also known as wings) of the guitar are then glued to this central piece. Some luthiers prefer this method of construction as they claim it allows better sustain of each note. Some instruments may not have a neck joint at all, having the neck and sides built as one piece and the body built around it.

The fingerboard, also called the fretboard, is a piece of wood embedded with metal frets that comprises the top of the neck. It is flat on classical guitars and slightly curved crosswise on acoustic and electric guitars. The curvature of the fretboard is measured by the fretboard radius, which is the radius of a hypothetical circle of which the fretboard's surface constitutes a segment. The smaller the fretboard radius, the more noticeably curved the fretboard is. Most modern guitars feature a 12" neck radius, while older guitars from the 1960s and 1970s usually feature a 6-8" neck radius. Pinching a string against a fret on fretboard effectively shortens the vibrating length of the string, producing a higher pitch.

Fretboards are most commonly made of rosewood, ebony, maple, and sometimes manufactured using composite materials such as HPL or resin. See the section "Neck" below for the importance of the length of the fretboard in connection to other dimensions of the guitar. The fingerboard plays an essential role in the treble tone for acoustic guitars. The quality of vibration of the fingerboard is the principal characteristic for generating the best treble tone. For that reason, ebony wood is better, but because of high use, ebony has become rare and extremely expensive. Most guitar manufacturers have adopted rosewood instead of ebony.

Almost all guitars have frets, which are metal strips (usually nickel alloy or stainless steel) embedded along the fretboard and located at exact points that divide the scale length in accordance with a specific mathematical formula. The exceptions include fretless bass guitars and very rare fretless guitars. Pressing a string against a fret determines the strings' vibrating length and therefore its resultant pitch. The pitch of each consecutive fret is defined at a half-step interval on the chromatic scale. Standard classical guitars have 19 frets and electric guitars between 21 and 24 frets, although guitars have been made with as many as 27 frets. Frets are laid out to accomplish an equal tempered division of the octave. Each set of twelve frets represents an octave. The twelfth fret divides the scale length exactly into two halves, and the 24th fret position divides one of those halves in half again.

The ratio of the spacing of two consecutive frets is (twelfth root of two). In practice, luthiers determine fret positions using the constant 17.817—an approximation to 1/(1-1/). If the nth fret is a distance x from the bridge, then the distance from the (n+1)th fret to the bridge is x-(x/17.817).[15] Frets are available in several different gauges and can be fitted according to player preference. Among these are "jumbo" frets, which have much thicker gauge, allowing for use of a slight vibrato technique from pushing the string down harder and softer. "Scalloped" fretboards, where the wood of the fretboard itself is "scooped out" between the frets, allow a dramatic vibrato effect. Fine frets, much flatter, allow a very low string-action, but require that other conditions, such as curvature of the neck, be well-maintained to prevent buzz.

The truss rod is a thin, strong metal rod that runs along the inside of the neck. It is used to correct changes to the neck's curvature caused by aging of the neck timbers, changes in humidity, or to compensate for changes in the tension of strings. The tension of the rod and neck assembly is adjusted by a hex nut or an allen-key bolt on the rod, usually located either at the headstock, sometimes under a cover, or just inside the body of the guitar underneath the fretboard and accessible through the sound hole. Some truss rods can only be accessed by removing the neck. The truss rod counteracts the immense amount of tension the strings place on the neck, bringing the neck back to a straighter position. Turning the truss rod clockwise tightens it, counteracting the tension of the strings and straightening the neck or creating a backward bow. Turning the truss rod counter-clockwise loosens it, allowing string tension to act on the neck and creating a forward bow.

Adjusting the truss rod affects the intonation of a guitar as well as the height of the strings from the fingerboard, called the action. Some truss rod systems, called double action truss systems, tighten both ways, pushing the neck both forward and backward (standard truss rods can only release to a point beyond which the neck is no longer compressed and pulled backward). The artist and luthier Irving Sloane pointed out, in his book Steel-String Guitar Construction, that truss rods are intended primarily to remedy concave bowing of the neck, but cannot correct a neck with "back bow" or one that has become twisted. Classical guitars do not require truss rods, as their nylon strings exert a lower tensile force with lesser potential to cause structural problems. However, their necks are often reinforced with a strip of harder wood, such as an ebony strip that runs down the back of a cedar neck. There is no tension adjustment on this form of reinforcement.

Inlays are visual elements set into the exterior surface of a guitar, both for decoration and artistic purposes and, in the case of the markings on the 3rd, 5th, 7th and 12th fret (and in higher octaves), to provide guidance to the performer about the location of frets on the instrument. The typical locations for inlay are on the fretboard, headstock, and on acoustic guitars around the soundhole, known as the rosette. Inlays range from simple plastic dots on the fretboard to intricate works of art covering the entire exterior surface of a guitar (front and back). Some guitar players have used LEDs in the fretboard to produce unique lighting effects onstage. Fretboard inlays are most commonly shaped like dots, diamond shapes, parallelograms, or large blocks in between the frets.

Dots are usually inlaid into the upper edge of the fretboard in the same positions, small enough to be visible only to the player. These usually appear on the odd numbered frets, but also on the 12th fret (the one octave mark) instead of the 11th and 13th frets. Some older or high-end instruments have inlays made of mother of pearl, abalone, ivory, colored wood or other exotic materials and designs. Simpler inlays are often made of plastic or painted. High-end classical guitars seldom have fretboard inlays as a well-trained player is expected to know his or her way around the instrument. In addition to fretboard inlay, the headstock and soundhole surround are also frequently inlaid. The manufacturer's logo or a small design is often inlaid into the headstock. Rosette designs vary from simple concentric circles to delicate fretwork mimicking the historic rosette of lutes. Bindings that edge the finger and sound boards are sometimes inlaid. Some instruments have a filler strip running down the length and behind the neck, used for strength or to fill the cavity through which the truss rod was installed in the neck.

Body

Guitarist girl
In the guitar, the sound box is the hollowed wooden structure that constitutes the body of the instrument.

In acoustic guitars, string vibration is transmitted through the bridge and saddle to the body via sound board. The sound board is typically made of tone woods such as spruce or cedar. Timbers for tone woods are chosen for both strength and ability to transfer mechanical energy from the strings to the air within the guitar body. Sound is further shaped by the characteristics of the guitar body's resonant cavity. In expensive instruments, the entire body is made of wood. In inexpensive instruments, the back may be made of plastic.

In an acoustic instrument, the body of the guitar is a major determinant of the overall sound quality. The guitar top, or soundboard, is a finely crafted and engineered element made of tonewoods such as spruce and red cedar. This thin piece of wood, often only 2 or 3 mm thick, is strengthened by differing types of internal bracing. Many luthiers consider the top the dominant factor in determining the sound quality. The majority of the instrument's sound is heard through the vibration of the guitar top as the energy of the vibrating strings is transferred to it. The body of an acoustic guitar has a sound hole through which sound projects. The sound hole is usually a round hole in the top of the guitar under the strings. Air inside the body vibrates as the guitar top and body is vibrated by the strings, and the response of the air cavity at different frequencies is characterized, like the rest of the guitar body, by a number of resonance modes at which it responds more strongly.

The top, back and ribs of an acoustic guitar body are very thin (1–2 mm), so a flexible piece of wood called lining is glued into the corners where the rib meets the top and back. This interior reinforcement provides 5 to 20 mm of solid gluing area for these corner joints. Solid linings are often used in classical guitars, while kerfed lining is most often found in steel string acoustics. Kerfed lining is also called kerfing because it is scored, or "kerfed"(incompletely sawn through), to allow it to bend with the shape of the rib). During final construction, a small section of the outside corners is carved or routed out and filled with binding material on the outside corners and decorative strips of material next to the binding, which are called purfling. This binding serves to seal off the end grain of the top and back. Purfling can also appear on the back of an acoustic guitar, marking the edge joints of the two or three sections of the back. Binding and purfling materials are generally made of either wood or plastic.

Body size, shape and style has changed over time. 19th century guitars, now known as salon guitars, were smaller than modern instruments. Differing patterns of internal bracing have been used over time by luthiers. Torres, Hauser, Ramirez, Fleta, and C. F. Martin were among the most influential designers of their time. Bracing not only strengthens the top against potential collapse due to the stress exerted by the tensioned strings, but also affects the resonance characteristics of the top. The back and sides are made out of a variety of timbers such as mahogany, Indian rosewood and highly regarded Brazilian rosewood (Dalbergia nigra). Each one is primarily chosen for their aesthetic effect and can be decorated with inlays and purfling.

Instruments with larger areas for the guitar top were introduced by Martin in an attempt to create greater volume levels. The popularity of the larger "dreadnought" body size amongst acoustic performers is related to the greater sound volume produced.

Most electric guitar bodies are made of wood and include a plastic pick guard. Boards wide enough to use as a solid body are very expensive due to the worldwide depletion of hardwood stock since the 1970s, so the wood is rarely one solid piece. Most bodies are made from two pieces of wood with some of them including a seam running down the center line of the body. The most common woods used for electric guitar body construction include maple, basswood, ash, poplar, alder, and mahogany. Many bodies consist of good-sounding, but inexpensive woods, like ash, with a "top", or thin layer of another, more attractive wood (such as maple with a natural "flame" pattern) glued to the top of the basic wood. Guitars constructed like this are often called "flame tops". The body is usually carved or routed to accept the other elements, such as the bridge, pickup, neck, and other electronic components. Most electrics have a polyurethane or nitrocellulose lacquer finish. Other alternative materials to wood are used in guitar body construction. Some of these include carbon composites, plastic material, such as polycarbonate, and aluminum alloys.

The main purpose of the bridge on an acoustic guitar is to transfer the vibration from the strings to the soundboard, which vibrates the air inside of the guitar, thereby amplifying the sound produced by the strings. On all electric, acoustic and original guitars, the bridge holds the strings in place on the body. There are many varied bridge designs. There may be some mechanism for raising or lowering the bridge saddles to adjust the distance between the strings and the fretboard (action), or fine-tuning the intonation of the instrument. Some are spring-loaded and feature a "whammy bar", a removable arm that lets the player modulate the pitch by changing the tension on the strings. The whammy bar is sometimes also called a "tremolo bar". (The effect of rapidly changing pitch is properly called "vibrato". See Tremolo for further discussion of this term.) Some bridges also allow for alternate tunings at the touch of a button.

On almost all modern electric guitars, the bridge has saddles that are adjustable for each string so that intonation stays correct up and down the neck. If the open string is in tune, but sharp or flat when frets are pressed, the bridge saddle position can be adjusted with a screwdriver or hex key to remedy the problem. In general, flat notes are corrected by moving the saddle forward and sharp notes by moving it backwards. On an instrument correctly adjusted for intonation, the actual length of each string from the nut to the bridge saddle is slightly, but measurably longer than the scale length of the instrument. This additional length is called compensation, which flattens all notes a bit to compensate for the sharping of all fretted notes caused by stretching the string during fretting.

The saddle of a guitar refers to the part of the bridge that physically supports the strings. It may be one piece (typically on acoustic guitars) or separate pieces, one for each string (electric guitars and basses). The saddle's basic purpose is to provide the end point for the string's vibration at the correct location for proper intonation, and on acoustic guitars to transfer the vibrations through the bridge into the top wood of the guitar. Saddles are typically made of plastic or bone for acoustic guitars, though synthetics and some exotic animal tooth variations (e.g. fossilized tooth, ivory, etc. ) have become popular with some players. Electric guitar saddles are typically metal, though some synthetic saddles are available.

The pickguard, also known as the scratchplate, is usually a piece of laminated plastic or other material that protects the finish of the top of the guitar from damage due to the use of a plectrum ("pick") or fingernails. Electric guitars sometimes mount pickups and electronics on the pickguard. It is a common feature on steel-string acoustic guitars. Some performance styles that use the guitar as a percussion instrument (tapping the top or sides between notes, etc.), such as flamenco, require that a scratchplate or pickguard be fitted to nylon-string instruments.

Strings

The standard guitar has six strings, but four-, seven-, eight-, nine-, ten-, eleven-, twelve-, thirteen- and eighteen-string guitars are also available. Classical and flamenco guitars historically used gut strings, but these have been superseded by polymer materials, such as nylon and fluorocarbon. Modern guitar strings are constructed from metal, polymers, or animal or plant product materials. Instruments utilizing "steel" strings may have strings made from alloys incorporating steel, nickel or phosphor bronze. Bass strings for both instruments are wound rather than monofilament.

Pickups and electronics

Stratocaster detail DSC06937
This Fender Stratocaster has features common to many electric guitars: multiple pickups, a vibrato bar/vibrato unit, and volume and tone knobs.

Pickups are transducers attached to a guitar that detect (or "pick up") string vibrations and convert the mechanical energy of the string into electrical energy. The resultant electrical signal can then be electronically amplified. The most common type of pickup is electromagnetic in design. These contain magnets that are within a coil, or coils, of copper wire. Such pickups are usually placed directly underneath the guitar strings. Electromagnetic pickups work on the same principles and in a similar manner to an electric generator. The vibration of the strings creates a small electric current in the coils surrounding the magnets. This signal current is carried to a guitar amplifier that drives a loudspeaker.

Traditional electromagnetic pickups are either single-coil or double-coil. Single-coil pickups are susceptible to noise induced by stray electromagnetic fields, usually mains-frequency (60 or 50 hertz) hum. The introduction of the double-coil humbucker in the mid-1950s solved this problem through the use of two coils, one of which is wired in opposite polarity to cancel or "buck" stray fields.

The types and models of pickups used can greatly affect the tone of the guitar. Typically, humbuckers, which are two magnet-coil assemblies attached to each other, are traditionally associated with a heavier sound. Single-coil pickups, one magnet wrapped in copper wire, are used by guitarists seeking a brighter, twangier sound with greater dynamic range.

Modern pickups are tailored to the sound desired. A commonly applied approximation used in selection of a pickup is that less wire (lower electrical impedance) gives brighter sound, more wire gives a "fat" tone. Other options include specialized switching that produces coil-splitting, in/out of phase and other effects. Guitar circuits are either active, needing a battery to power their circuit, or, as in most cases, equipped with a passive circuit.

Fender Stratocaster-type guitars generally utilize three single-coil pickups, while most Gibson Les Paul types use humbucker pickups.

Piezoelectric, or piezo, pickups represent another class of pickup. These employ piezoelectricity to generate the musical signal and are popular in hybrid electro-acoustic guitars. A crystal is located under each string, usually in the saddle. When the string vibrates, the shape of the crystal is distorted, and the stresses associated with this change produce tiny voltages across the crystal that can be amplified and manipulated. Piezo pickups usually require a powered pre-amplifier to lift their output to match that of electromagnetic pickups. Power is typically delivered by an on-board battery.

Most pickup-equipped guitars feature onboard controls, such as volume or tone, or pickup selection. At their simplest, these consist of passive components, such as potentiometers and capacitors, but may also include specialized integrated circuits or other active components requiring batteries for power, for preamplification and signal processing, or even for electronic tuning. In many cases, the electronics have some sort of shielding to prevent pickup of external interference and noise.

Guitars may be shipped or retrofitted with a hexaphonic pickup, which produces a separate output for each string, usually from a discrete piezoelectric or magnetic pickup. This arrangement lets on-board or external electronics process the strings individually for modeling or Musical Instrument Digital Interface (MIDI) conversion. Roland makes "GK" hexaphonic pickups for guitar and bass, and a line of guitar modeling and synthesis products.[16] Line 6's hexaphonic-equipped Variax guitars use on-board electronics to model the sound after various vintage instruments, and vary pitch on individual strings.

MIDI converters use a hexaphonic guitar signal to determine pitch, duration, attack, and decay characteristics. The MIDI sends the note information to an internal or external sound bank device. The resulting sound closely mimics numerous instruments. The MIDI setup can also let the guitar be used as a game controller (i.e., Rock Band Squier) or as an instructional tool, as with the Fretlight Guitar.

Tuning

Notationally, the guitar is considered a transposing instrument. Its pitch sounds one octave lower than it is notated on a score.

Standard

Standard diagonal shifting of C major chord
In standard tuning, the C-major chord has three shapes because of the irregular major-third between the G- and B-strings.

A variety of tunings may be used. The most common tuning, known as "Standard Tuning", has the strings tuned from a low E, to a high E, traversing a two octave range—EADGBE. When all strings are played open the resulting chord is an Em7/add11.

The pitches are as follows:

String Scientific
pitch
Helmholtz
pitch
Interval from middle C Frequency
(Hz)
1st E4 e' major third above 329.63
2nd B3 b minor second below 246.94
3rd G3 g perfect fourth below 196.00
4th D3 d minor seventh below 146.83
5th A2 A minor tenth below 110.00
6th E2 E minor thirteenth below 82.41

The table below shows a pitch's name found over the six strings of a guitar in standard tuning, from the nut (zero), to the twelfth fret.

E F F G A A B B C C D E E
Tuning ADGBE5 ADGBE0
In the standard guitar-tuning, one major-third interval is interjected amid four perfect-fourth intervals. In each regular tuning, all string successions have the same interval.

For four strings, the 5th fret on one string is the same open-note as the next string; for example, a 5th-fret note on the sixth string is the same note as the open fifth string. However, between the second and third strings, an irregularity occurs: The 4th-fret note on the third string is equivalent to the open second string.

Alternative

Diagonal shift of C-major chord in major-thirds tuning
Chords can be shifted diagonally in major-thirds tuning and other regular tunings. In standard tuning, chords change their shape because of the irregular major-third G-B.

Standard tuning has evolved to provide a good compromise between simple fingering for many chords and the ability to play common scales with reasonable left-hand movement. There are also a variety of commonly used alternative tunings, for example, the classes of open, regular, and dropped tunings.

Ry Cooder playing
Ry Cooder plays slide-guitar with open tunings.

Open tuning refers to a guitar tuned so that strumming the open strings produces a chord, typically a major chord. The base chord consists of at least 3 notes and may include all the strings or a subset. The tuning is named for the open chord, Open D, open G, and open A are popular tunings. All similar chords in the chromatic scale can then be played by barring a single fret.[17] Open tunings are common in blues and folk music,[18] and they are used in the playing of slide and bottleneck guitars.[17][19] Many musicians use open tunings when playing slide guitar.[18]

For the standard tuning, there is exactly one interval of a major third between the second and third strings, and all the other intervals are fourths. The irregularity has a price - chords cannot be shifted around the fretboard in the standard tuning E-A-D-G-B-E, which requires four chord-shapes for the major chords. There are separate chord-forms for chords having their root note on the third, fourth, fifth, and sixth strings.[20]

In contrast, regular tunings have equal intervals between the strings,[21] and so they have symmetrical scales all along the fretboard. This makes it simpler to translate chords. For the regular tunings, chords may be moved diagonally around the fretboard. The diagonal movement of chords is especially simple for the regular tunings that are repetitive, in which case chords can be moved vertically: Chords can be moved three strings up (or down) in major-thirds tuning and chords can be moved two strings up (or down) in augmented-fourths tuning. Regular tunings thus appeal to new guitarists and also to jazz-guitarists, whose improvisation is simplified by regular intervals.

On the other hand, some chords are more difficult to play in a regular tuning than in standard tuning. It can be difficult to play conventional chords especially in augmented-fourths tuning and all-fifths tuning,[21] in which the large spacings require hand stretching. Some chords, which are conventional in folk music, are difficult to play even in all-fourths and major-thirds tunings, which do not require more hand-stretching than standard tuning.[22]

  • In major-thirds tuning, the interval between open strings is always a major third. Consequently, four frets suffice to play the chromatic scale. Chord inversion is especially simple in major-thirds tuning. Chords are inverted simply by raising one or two notes by three strings. The raised notes are played with the same finger as the original notes.[23][24] In contrast, in standard tuning, the shape of inversions depends on the involvement of the irregular major-third.[25]
  • All-fourths tuning replaces the major third between the third and second strings with a fourth, extending the conventional tuning of a bass guitar. With all-fourths tuning, playing the triads is more difficult, but improvisation is simplified, because chord-patterns remain constant when moved around the fretboard. Jazz guitarist Stanley Jordan uses the all-fourths tuning EADGCF. Invariant chord-shapes are an advantage of other regular tunings, such as major-thirds and all-fifths tunings.[21]
  • Extending the tunings of violins and cellos, all-fifths tuning offers an expanded range CGDAEB,[26] which however has been impossible to implement on a conventional guitar. All-fifths tuning is used for the lowest five strings of the new standard tuning of Robert Fripp and his former students in Guitar Craft courses; new standard tuning has a high G on its last string CGDAE-G.[27][28]

Another class of alternative tunings are called drop tunings, because the tuning drops down the lowest string. Dropping down the lowest string a whole tone results in the "drop-D" (or "dropped D") tuning. Its open-string notes DADGBE (from low to high) allow for a deep bass D note, which can be used in keys such as D major, d minor and G major. It simplifies the playing of simple fifths (powerchords). Many contemporary rock bands re-tune all strings down, making, for example, Drop-C or Drop-B tunings.

Scordatura

Many scordatura (alternate tunings) modify the standard tuning of the lute, especially when playing Renaissance music repertoire originally written for that instrument. Some scordatura drop the pitch of one or more strings, giving access to new lower notes. Some scordatura make it easier to play in unusual keys.

Accessories

Though a guitar may be played on its own, there are a variety of common accessories used for holding and playing the guitar.

Capotasto

A capo (short for capotasto) is used to change the pitch of open strings.[29] Capos are clipped onto the fretboard with the aid of spring tension, or in some models, elastic tension. To raise the guitar's pitch by one semitone, the player would clip the capo onto the fretboard just below the first fret. Its use allows players to play in different keys without having to change the chord formations they use. For example, if a folk guitar player wanted to play a song in the key of B Major, they could put a capo on the second fret of the instrument, and then play the song as if it were in the key of A Major, but with the capo the instrument would make the sounds of B Major. This is because with the capo barring the entire second fret, open chords would all sound two semitones (aka one tone) higher in pitch. For example, if a guitarist played an open A Major chord (a very common open chord), it would sound like a B Major chord. All of the other open chords would be similarly modified in pitch. Because of the ease with which they allow guitar players to change keys, they are sometimes referred to with pejorative names, such as "cheaters" or the "hillbilly crutch". Despite this negative viewpoint, another benefit of the capo is that it enables guitarists to obtain the ringing, resonant sound of the common keys (C, G, A, etc.) in "harder" and less-commonly used keys. Classical performers are known to use them to enable modern instruments to match the pitch of historical instruments such as the Renaissance music lute.

Slides

Fingandslide
Example of a bottleneck slide, with fingerpicks and a resonator guitar made of metal.

A slide, (neck of a bottle, knife blade or round metal or glass bar or cylinder) is used in blues and rock to create a glissando or "Hawaiian" effect. The slide is used to fret notes on the neck, instead of using the fretting hand's fingers. The characteristic use of the slide is to move up to the intended pitch by, as the name implies, sliding up the neck to the desired note. The necks of bottles were often used in blues and country music as improvised slides. Modern slides are constructed of glass, plastic, ceramic, chrome, brass or steel bars or cylinders, depending on the weight and tone desired (and the amount of money a guitarist can spend). An instrument that is played exclusively in this manner (using a metal bar) is called a steel guitar or pedal steel. Slide playing to this day is very popular in blues music and country music. Some slide players use a so-called Dobro guitar. Some performers who have become famous for playing slide are Robert Johnson, Elmore James, Ry Cooder, George Harrison, Bonnie Raitt, Derek Trucks, Warren Haynes, Duane Allman, Muddy Waters, Rory Gallagher, and George Thorogood.

Plectrum

Guitar picks-KayEss-1.jpeg
A variety of guitar picks

A "guitar pick" or "plectrum" is a small piece of hard material generally held between the thumb and first finger of the picking hand and is used to "pick" the strings. Though most classical players pick with a combination of fingernails and fleshy fingertips, the pick is most often used for electric and steel-string acoustic guitars. Though today they are mainly plastic, variations do exist, such as bone, wood, steel or tortoise shell. Tortoise shell was the most commonly used material in the early days of pick-making, but as tortoises and turtles became endangered, the practice of using their shells for picks or anything else was banned. Tortoise-shell picks made before the ban are often coveted for a supposedly superior tone and ease of use, and their scarcity has made them valuable.

Picks come in many shapes and sizes. Picks vary from the small jazz pick to the large bass pick. The thickness of the pick often determines its use. A thinner pick (between 0.2 and 0.5 mm) is usually used for strumming or rhythm playing, whereas thicker picks (between 0.7 and 1.5+ mm) are usually used for single-note lines or lead playing. The distinctive guitar sound of Billy Gibbons is attributed to using a quarter or peso as a pick. Similarly, Brian May is known to use a sixpence coin as a pick, while noted 1970s and early 1980s session musician David Persons is known for using old credit cards, cut to the correct size, as plectrums.

Thumb picks and finger picks that attach to the finger tips are sometimes employed in finger-picking styles on steel strings. These allow the fingers and thumb to operate independently, whereas a flat pick requires the thumb and one or two fingers to manipulate.

Straps

A guitar strap is a strip of material with an attachment mechanism on each end, made to hold a guitar via the shoulders at an adjustable length. Guitars have varying accommodations for attaching a strap. The most common are strap buttons, also called strap pins, which are flanged steel posts anchored to the guitar with screws. Two strap buttons come pre-attached to virtually all electric guitars, and many steel-string acoustic guitars. Strap buttons are sometimes replaced with "strap locks", which connect the guitar to the strap more securely.

The lower strap button is usually located at the bottom (bridge end) of the body. The upper strap button is usually located near or at the top (neck end) of the body: on the upper body curve, at the tip of the upper "horn" (on a double cutaway), or at the neck joint (heel). Some electrics, especially those with odd-shaped bodies, have one or both strap buttons on the back of the body. Some Steinberger electric guitars, owing to their minimalist and lightweight design, have both strap buttons at the bottom of the body. Rarely, on some acoustics, the upper strap button is located on the headstock. Some acoustic and classical guitars only have a single strap button at the bottom of the body—the other end must be tied onto the headstock, above the nut and below the machine heads.

Amplifiers, effects and speakers

Electric guitars and bass guitars have to be used with a guitar amplifier and loudspeaker or a bass amplifier and speaker, respectively, in order to make enough sound to be heard by the performer and audience. Electric guitars and bass guitars almost always use magnetic pickups, which generate an electric signal when the musician plucks, strums or otherwise plays the instrument. The amplifier and speaker strengthen this signal using a power amplifier and a loudspeaker. Acoustic guitars that are equipped with a piezoelectric pickup or microphone can also be plugged into an instrument amplifier, acoustic guitar amp or PA system to make them louder. With electric guitar and bass, the amplifier and speaker are not just used to make the instrument louder; by adjusting the equalizer controls, the preamplifier, and any onboard effects units (reverb, distortion/overdrive, etc.) the player can also modify the tone (aka timbre or "colour") and sound of the instrument. Acoustic guitar players can also use the amp to change the sound of their instrument, but in general, acoustic guitar amps are used to make the natural acoustic sound of the instrument louder without changing its sound that much.

Acoustic guitar

An acoustic guitar is a guitar that produces sound acoustically by transmitting the vibration of the strings to the air—as opposed to relying on electronic amplification (see electric guitar). The sound waves from the strings of an acoustic guitar resonate through the guitar's body, creating sound. This typically involves the use of a sound board and a sound box to strengthen the vibrations of the strings. In standard tuning the guitar's six strings are tuned (low to high) E2 A2 D3 G3 B3 E4.

The main source of sound in an acoustic guitar is the string, which is plucked or strummed with the finger or with a pick. The string vibrates at a necessary frequency and also creates many harmonics at various different frequencies. The frequencies produced can depend on string length, mass, and tension. The string causes the soundboard and sound box to vibrate, and as these have their own resonances at certain frequencies, they amplify some string harmonics more strongly than others, hence affecting the timbre produced by the instrument.

Bass guitar

The bass guitar (also known as electric bass, or simply bass) is a stringed instrument similar in appearance and construction to an electric guitar, except with a longer neck and scale length, and four to six strings or courses.

The four-string bass is usually tuned the same as the double bass, which corresponds to pitches one octave lower than the four lowest-pitched strings of a guitar (E, A, D, and G). It is played primarily with the fingers or thumb, or striking with a pick. The electric bass guitar has pickups and must be connected to an amplifier and speaker to be loud enough to compete with other instruments.

Since the 1960s, the bass guitar has largely replaced the double bass in popular music as the bass instrument in the rhythm section. While types of basslines vary widely from one style of music to another, the bassist usually plays a similar role: anchoring the harmonic framework and establishing the beat. Many styles of music include the bass guitar, and it is occasionally a soloing instrument.

Brian May

Brian Harold May, (born 19 July 1947) is an English musician, singer, songwriter, and astrophysicist. He is best known as the lead guitarist of the rock band Queen. He uses a home-built electric guitar called the Red Special. His compositions for the band include "We Will Rock You", "Tie Your Mother Down", "I Want It All", "Fat Bottomed Girls", "Flash", "Hammer to Fall", "Save Me", "Who Wants to Live Forever", and "The Show Must Go On".

May was a co-founder of Queen with lead singer Freddie Mercury and drummer Roger Taylor, having previously performed with Taylor in the band Smile, which he had joined while he was at university. Within five years of their formation in 1970 and the recruitment of bass player John Deacon completing the lineup, Queen had become one of the biggest rock bands in the world with the success of the album A Night at the Opera and its single "Bohemian Rhapsody". From the mid-1970s until the early 1990s, Queen were an almost constant presence in the UK charts and played some of the biggest venues in the world, most notably giving an acclaimed performance at Live Aid in 1985. As a member of Queen, May became regarded as a virtuoso musician and he was identified with a distinctive sound created through his layered guitar work.

Following the death of Mercury in 1991, Queen were put on hiatus for several years but were eventually reconvened by May and Taylor for further performances featuring other vocalists. In 2005, a Planet Rock poll saw May voted the seventh greatest guitarist of all time. He was ranked at No. 26 on Rolling Stone's list of the "100 Greatest Guitarists of All Time". In 2012, he was ranked the second greatest guitarist in a Guitar World magazine readers poll. In 2001, he was inducted into the Rock and Roll Hall of Fame as one of the band's members, and in 2018 he received the Grammy Lifetime Achievement Award which recognises "the most distinctive recordings in music history".May was appointed a CBE by Queen Elizabeth II in 2005 for "services to the music industry and for charity work". May earned a PhD in astrophysics from Imperial College London in 2007, and was Chancellor of Liverpool John Moores University from 2008 to 2013. He was a "science team collaborator" with NASA's New Horizons Pluto mission. He is also a co-founder of the awareness campaign Asteroid Day. Asteroid 52665 Brianmay was named after him. May is also an animal rights activist, campaigning against the hunting of foxes and the culling of badgers in the UK.

Dimebag Darrell

Darrell Lance Abbott (August 20, 1966 – December 8, 2004), also known as Diamond Darrell and later Dimebag Darrell, was an American musician and songwriter. He co-founded the heavy metal bands Pantera and Damageplan alongside his brother Vinnie Paul. He was considered to be one of the driving forces behind groove metal, and is also considered by many to be one of the most influential guitarists in heavy metal history.

Abbott was shot and killed by a gunman while on stage during a performance with Damageplan on December 8, 2004. He ranked No. 92 in Rolling Stone's 100 Greatest Guitarists and No. 1 in Metal Hammer. In 2012, he was ranked the ninth-greatest guitarist of all time by a Guitar World reader's poll.

Electric guitar

An electric guitar is a guitar that uses one or more pickups to convert the vibration of its strings into electrical signals. The vibration occurs when a guitar player strums, plucks, fingerpicks, slaps or taps the strings. The pickup generally uses electromagnetic induction to create this signal, which being relatively weak is fed into a guitar amplifier before being sent to the speaker(s), which converts it into audible sound.

The electric signal can be electronically altered to change the timbre of the sound. Often, the signal is modified using effects such as reverb, distortion and "overdrive"; the latter is considered to be a key element of electric blues guitar music and rock guitar playing.

Invented in 1931, the electric guitar was adopted by jazz guitar players, who wanted to play single-note guitar solos in large big band ensembles. Early proponents of the electric guitar on record include Les Paul, Lonnie Johnson, Sister Rosetta Tharpe, T-Bone Walker, and Charlie Christian. During the 1950s and 1960s, the electric guitar became the most important instrument in popular music. It has evolved into an instrument that is capable of a multitude of sounds and styles in genres ranging from pop and rock to country music, blues and jazz. It served as a major component in the development of electric blues, rock and roll, rock music, heavy metal music and many other genres of music.

Electric guitar design and construction varies greatly in the shape of the body and the configuration of the neck, bridge, and pickups. Guitars may have a fixed bridge or a spring-loaded hinged bridge, which lets players "bend" the pitch of notes or chords up or down, or perform vibrato effects. The sound of an electric guitar can be modified by new playing techniques such as string bending, tapping, and hammering-on, using audio feedback, or slide guitar playing.

There are several types of electric guitar, including: the solid-body guitar; various types of hollow-body guitars; the six-string guitar (the most common type), which is usually tuned E, B, G, D, A, E, from highest to lowest strings; the seven-string guitar, which typically adds a low B string below the low E; and the twelve-string guitar, which has six pairs of strings.

In pop and rock music, the electric guitar is often used in two roles: as a rhythm guitar, which plays the chord sequences or progressions, and riffs, and sets the beat (as part of a rhythm section); and as a lead guitar, which provides instrumental melody lines, melodic instrumental fill passages, and solos. In a small group, such as a power trio, one guitarist switches between both roles. In large rock and metal bands, there is often a rhythm guitarist and a lead guitarist.

Eric Clapton

Eric Patrick Clapton, (born 30 March 1945) is an English rock and blues guitarist, singer, and songwriter. He is the only three-time inductee to the Rock and Roll Hall of Fame: once as a solo artist and separately as a member of the Yardbirds and of Cream. Clapton has been referred to as one of the most important and influential guitarists of all time. Clapton ranked second in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time" and fourth in Gibson's "Top 50 Guitarists of All Time". He was also named number five in Time magazine's list of "The 10 Best Electric Guitar Players" in 2009.In the mid-1960s Clapton left the Yardbirds to play with John Mayall & the Bluesbreakers. Immediately after leaving Mayall, Clapton formed the power trio Cream with drummer Ginger Baker and bassist Jack Bruce, in which Clapton played sustained blues improvisations and "arty, blues-based psychedelic pop". After Cream broke up, he formed blues rock band Blind Faith with Baker, Steve Winwood, and Ric Grech. Clapton's solo career began in the 1970s, where his work bore the influence of the mellow style of J. J. Cale and the reggae of Bob Marley. His version of Marley's "I Shot the Sheriff" helped reggae reach a mass market. Two of his most popular recordings were "Layla", recorded with Derek and the Dominos; and Robert Johnson's "Crossroads", recorded with Cream. Following the death of his son Conor in 1991, Clapton's grief was expressed in the song "Tears in Heaven", which was featured on his Unplugged album.

Clapton has been the recipient of 18 Grammy Awards, and the Brit Award for Outstanding Contribution to Music. In 2004 he was awarded a CBE at Buckingham Palace for services to music. He has received four Ivor Novello Awards from the British Academy of Songwriters, Composers and Authors, including the Lifetime Achievement Award. In his solo career, Clapton has sold more than 100 million records worldwide, making him one of the best-selling musicians of all time. In 1998, Clapton, a recovering alcoholic and drug addict, founded the Crossroads Centre on Antigua, a medical facility for recovering substance abusers.

George Harrison

George Harrison (25 February 1943 – 29 November 2001) was an English musician, singer-songwriter, music and film producer who achieved international fame as the lead guitarist of the Beatles. Often referred to as "the quiet Beatle", Harrison embraced Indian culture and helped broaden the scope of popular music through his incorporation of Indian instrumentation and Hindu-aligned spirituality in the Beatles' work. Although the majority of the band's songs were written by John Lennon and Paul McCartney, most Beatles albums from 1965 onwards contained at least two Harrison compositions. His songs for the group included "Taxman", "Within You Without You", "While My Guitar Gently Weeps", "Here Comes the Sun" and "Something".

Harrison's earliest musical influences included George Formby and Django Reinhardt; Carl Perkins, Chet Atkins and Chuck Berry were subsequent influences. By 1965, he had begun to lead the Beatles into folk rock through his interest in Bob Dylan and the Byrds, and towards Indian classical music through his use of the sitar on "Norwegian Wood (This Bird Has Flown)". Having initiated the band's embracing of Transcendental Meditation in 1967, he subsequently developed an association with the Hare Krishna movement. After the band's break-up in 1970, Harrison released the triple album All Things Must Pass, a critically acclaimed work that produced his most successful hit single, "My Sweet Lord", and introduced his signature sound as a solo artist, the slide guitar. He also organised the 1971 Concert for Bangladesh with Indian musician Ravi Shankar, a precursor to later benefit concerts such as Live Aid. In his role as a music and film producer, Harrison produced acts signed to the Beatles' Apple record label before founding Dark Horse Records in 1974 and co-founding HandMade Films in 1978.

Harrison released several best-selling singles and albums as a solo performer. In 1988, he co-founded the platinum-selling supergroup the Traveling Wilburys. A prolific recording artist, he was featured as a guest guitarist on tracks by Badfinger, Ronnie Wood and Billy Preston, and collaborated on songs and music with Dylan, Eric Clapton, Ringo Starr and Tom Petty, among others. Rolling Stone magazine ranked him number 11 in their list of the "100 Greatest Guitarists of All Time". He is a two-time Rock and Roll Hall of Fame inductee – as a member of the Beatles in 1988, and posthumously for his solo career in 2004.Harrison's first marriage, to model Pattie Boyd in 1966, ended in divorce in 1977. The following year he married Olivia Arias, with whom he had a son, Dhani. Harrison died from lung cancer in 2001 at the age of 58, two years after surviving a knife attack by an intruder at his Friar Park home. His remains were cremated and the ashes were scattered according to Hindu tradition in a private ceremony in the Ganges and Yamuna rivers in India. He left an estate of almost £100 million.

Guitar Hero

The Guitar Hero series (sometimes referred to as the Hero series) is a series of music rhythm games first published in 2005 by RedOctane and Harmonix, and distributed by Activision, in which players use a guitar-shaped game controller to simulate playing lead, bass guitar, and rhythm guitar across numerous rock music songs. Players match notes that scroll on-screen to colored fret buttons on the controller, strumming the controller in time to the music in order to score points, and keep the virtual audience excited. The games attempt to mimic many features of playing a real guitar, including the use of fast-fingering hammer-ons and pull-offs and the use of the whammy bar to alter the pitch of notes. Most games support single player modes, typically a Career mode to play through all the songs in the game, and both competitive and cooperative multiplayer modes. With the introduction of Guitar Hero World Tour in 2008, the game includes support for a four-player band including vocals and drums. The series initially used mostly cover versions of songs created by WaveGroup Sound, but most recent titles feature soundtracks that are fully master recordings, and in some cases, special re-recordings, of the songs. Later titles in the series feature support for downloadable content in the form of new songs.

In 2005, RedOctane, a company specializing in the manufacture of unique game controllers, was inspired to create Guitar Hero based on RedOctane's experience creating hardware for Konami's Guitar Freaks arcade game. They enlisted Harmonix, who previously developed several music video games, for development assistance. The first game in the series was made on a budget of $1 million. The series became extremely successful, leading to the acquisition of RedOctane by Activision in 2007. Harmonix was acquired by MTV Games and went on to create the Rock Band series of music games in the same vein as Guitar Hero. Activision brought Neversoft (primarily known for their Tony Hawk series of skateboarding games) on board for future development duties. Additional companies, such as Budcat Creations and Vicarious Visions have assisted in the adaptation of the games for other systems.

The series currently has ten major releases (seven Guitar Hero games, two DJ Hero games and Band Hero) and five expansions on gaming consoles. There are spin-offs for Windows and Macintosh systems, mobile phones, the Nintendo DS (the Guitar Hero: On Tour series), and an arcade game. The Guitar Hero franchise was a primary brand during the emergence of the popularity of rhythm games as a cultural phenomenon in North America. Such games have been utilized as a learning and development tool for medical purposes. The first game in the series was considered by several journalists to be one of the most influential video games of the first decade of the 21st century. The series has sold more than 25 million units worldwide, earning US$2 billion at retail, claimed by Activision to be the 3rd largest game franchise after the Mario and Madden NFL franchises; the third main title of the series, Guitar Hero III: Legends of Rock is also claimed by Activision to be the first single video game title to exceed $1 billion in sales.

Despite early success, the series, along with the overall rhythm game genre, suffered from poor sales starting in 2009. Company spokesman Eric Hollreiser said consumer research suggested continued solid demand for the series. Still, by early 2011, Activision stated that the series was on hiatus for 2011, while a seventh main title in the series was under development; this title was later cancelled due to the poor quality of the emerging product. Activision later shut down sales of the series' downloadable content, although users who purchased material from it previously may still play what they bought.

In 2015, Activision announced the first new title to the series in 5 years, Guitar Hero Live, released in October 2015. The title is considered a reboot of the series, with development being performed by FreeStyleGames, who had developed the DJ Hero games previously. As of December 1, 2018, Activision disabled the GHTV servers for Guitar Hero Live, reducing playable content from approximately 500 songs to 42 on disc tracks.

Guitarist

A guitarist (or a guitar player) is a person who plays the guitar. Guitarists may play a variety of guitar family instruments such as classical guitars, acoustic guitars, electric guitars, and bass guitars. Some guitarists accompany themselves on the guitar by singing or playing the harmonica.

Jimi Hendrix

James Marshall Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American rock guitarist, singer, and songwriter. Although his mainstream career spanned only four years, he is widely regarded as one of the most influential electric guitarists in the history of popular music, and one of the most celebrated musicians of the 20th century. The Rock and Roll Hall of Fame describes him as "arguably the greatest instrumentalist in the history of rock music".Born in Seattle, Washington, Hendrix began playing guitar at the age of 15. In 1961, he enlisted in the U.S. Army and trained as a paratrooper in the 101st Airborne Division; he was granted an honorable discharge the following year. Soon afterward, he moved to Clarksville, Tennessee, and began playing gigs on the Chitlin' Circuit, earning a place in the Isley Brothers' backing band and later with Little Richard, with whom he continued to work through mid-1965. He then played with Curtis Knight and the Squires before moving to England in late 1966 after being discovered by Linda Keith, who in turn interested bassist Chas Chandler of the Animals in becoming his first manager. Within months, Hendrix had earned three UK top ten hits with the Jimi Hendrix Experience: "Hey Joe", "Purple Haze", and "The Wind Cries Mary". He achieved fame in the U.S. after his performance at the Monterey Pop Festival in 1967, and in 1968 his third and final studio album, Electric Ladyland, reached number one in the U.S.; it was Hendrix's most commercially successful release and his first and only number one album. The world's highest-paid performer, he headlined the Woodstock Festival in 1969 and the Isle of Wight Festival in 1970, before his accidental death from barbiturate-related asphyxia on September 18, 1970, at the age of 27.

Hendrix was inspired musically by American rock and roll and electric blues. He favored overdriven amplifiers with high volume and gain, and was instrumental in popularizing the previously undesirable sounds caused by guitar amplifier feedback. He was also one of the first guitarists to make extensive use of tone-altering effects units, such as fuzz tone, Octavia, wah-wah, and Uni-Vibe in mainstream rock. He was the first artist to use stereophonic phasing effects in music recordings. Holly George-Warren of Rolling Stone commented: "Hendrix pioneered the use of the instrument as an electronic sound source. Players before him had experimented with feedback and distortion, but Hendrix turned those effects and others into a controlled, fluid vocabulary every bit as personal as the blues with which he began."Hendrix was the recipient of several music awards during his lifetime and posthumously. In 1967, readers of Melody Maker voted him the Pop Musician of the Year, and in 1968, Rolling Stone declared him the Performer of the Year. Disc and Music Echo honored him with the World Top Musician of 1969 and in 1970, Guitar Player named him the Rock Guitarist of the Year. The Jimi Hendrix Experience was inducted into the Rock and Roll Hall of Fame in 1992 and the UK Music Hall of Fame in 2005. Rolling Stone ranked the band's three studio albums, Are You Experienced, Axis: Bold as Love, and Electric Ladyland, among the 100 greatest albums of all time, and they ranked Hendrix as the greatest guitarist and the sixth greatest artist of all time.

Jimmy Page

James Patrick Page (born 9 January 1944) is an English musician, songwriter, and record producer who achieved international success as the guitarist and founder of the rock band Led Zeppelin.

Page began his career as a studio session musician in London and, by the mid-1960s, alongside Big Jim Sullivan, was one of the most sought-after session guitarists in Britain. He was a member of the Yardbirds from 1966 to 1968. In late 1968, he founded Led Zeppelin.

Page is widely considered to be one of the greatest and most influential guitarists of all time. Rolling Stone magazine has described Page as "the pontiff of power riffing" and ranked him number three in their list of the "100 Greatest Guitarists of All Time", behind Jimi Hendrix and Eric Clapton. In 2010, he was ranked number two in Gibson's list of "Top 50 Guitarists of All Time" and, in 2007, number four on Classic Rock's "100 Wildest Guitar Heroes". He was inducted into the Rock and Roll Hall of Fame twice; once as a member of the Yardbirds (1992) and once as a member of Led Zeppelin (1995).

John Deacon

John Richard Deacon (born 19 August 1951) is an English retired musician, best known for being the bass guitarist for the rock band Queen. He composed several songs for the group—including Top 10 hits "You're My Best Friend", "Another One Bites the Dust", "Back Chat", and "I Want to Break Free"—and was involved in the band's financial management.

Deacon grew up in Oadby, Leicestershire, playing bass in a local band, The Opposition, before moving to study electronics at Chelsea College, London. He joined Queen in 1971 on the strength of his musical and electronic skills, particularly the home-made Deacy Amp which guitarist Brian May used to create guitar orchestras throughout Queen's career. From the third album, Sheer Heart Attack, onwards, he wrote at least one song per album, several of which became hits. As well as bass, Deacon played some guitar and keyboards on Queen's studio work.

Following lead singer Freddie Mercury's death in 1991, and the following year's Tribute Concert, Deacon only performed a few times with the remaining members of Queen before retiring from the music industry in 1997 after recording "No-One but You (Only the Good Die Young)". He has not performed on any of the other projects that the other two surviving members, Brian May and Roger Taylor, have put together.

Keith Richards

Keith Richards (born 18 December 1943 is an English musician, singer and songwriter, best known as the co-founder, guitarist, backing vocalist, and co-principal songwriter of the Rolling Stones. Rolling Stone magazine called Richards the creator of "rock's greatest single body of riffs" on guitar and ranked him fourth on its list of 100 best guitarists in 2011, and the magazine lists fourteen songs that Richards wrote with the Rolling Stones' lead vocalist Mick Jagger on its "Rolling Stone's 500 Greatest Songs of All Time" list.

Richards plays both lead and rhythm guitar parts, often in the same song, as the Stones are generally known for their guitar interplay of rhythm and lead ("weaving") between Richards and the other guitarist in the band – Brian Jones (1962–1969), Mick Taylor (1969–1975), and Ronnie Wood (1975–present). In the recording studio Richards sometimes plays all of the guitar parts, notably on the songs "Paint It Black", "Ruby Tuesday", "Sympathy for the Devil", "(I Can't Get No) Satisfaction", and "Gimme Shelter". He is also a vocalist, singing backing vocals on many Rolling Stones songs as well as occasional lead vocals, such as on the Rolling Stones' 1972 single "Happy", as well as with his side project, the X-Pensive Winos.

Pop rock

Pop rock (also typeset as pop/rock) is rock music with a greater emphasis on professional songwriting and recording craft, and less emphasis on attitude. Originating in the 1950s as an alternative to rock and roll, early pop rock was influenced by the beat, arrangements, and style of rock and roll (and sometimes doo-wop). It may be viewed as a distinct genre field, rather than music that overlaps with pop and rock. The detractors of pop rock often deride it as a slick, commercial product, less authentic than rock music.

Queen (band)

Queen are a British rock band formed in London in 1970. Their classic line-up was Freddie Mercury (lead vocals and piano), Brian May (lead guitar and vocals), Roger Taylor (drums and vocals), and John Deacon (bass guitar). Their earliest works were influenced by progressive rock, hard rock and heavy metal, but the band gradually ventured into more conventional and radio-friendly works by incorporating further styles, such as arena rock and pop rock.

Before forming Queen, May and Taylor had played together in the band Smile. Mercury was a fan of Smile and encouraged them to experiment with more elaborate stage and recording techniques. He joined in 1970 and suggested the name "Queen". Deacon was recruited before the band recorded their eponymous debut album in 1973. Queen first charted in the UK with their second album, Queen II, in 1974. Sheer Heart Attack later that year and A Night at the Opera in 1975 brought them international success. The latter featured "Bohemian Rhapsody", which stayed at number one in the UK for nine weeks and helped popularise the music video.

The band’s 1977 album News of the World contained "We Will Rock You" and "We Are the Champions", which have become anthems at sporting events. By the early 1980s, Queen were one of the biggest stadium rock bands in the world. "Another One Bites the Dust" (1980) became their best-selling single, while their 1981 compilation album Greatest Hits is the best-selling album in the UK and is certified eight times platinum in the US. Their performance at the 1985 Live Aid concert has been ranked among the greatest in rock history by various publications. Mercury gave his last performance at Knebworth, England, in August 1986, with Queen. In 1991, he died of bronchopneumonia, a complication of AIDS, and Deacon retired in 1997. May and Taylor have performed under the Queen name with vocalists Paul Rodgers and Adam Lambert since.

Estimates of Queen's record sales range from 170 million to 300 million records, making them one of the world's best-selling music artists. Queen received the Outstanding Contribution to British Music Award from the British Phonographic Industry in 1990. They were inducted into the Rock and Roll Hall of Fame in 2001. Each member has composed hit singles, and all four were inducted into the Songwriters Hall of Fame in 2003. In 2005, Queen received the Ivor Novello Award for Outstanding Song Collection from the British Academy of Songwriters, Composers, and Authors. In 2018 they were presented the Grammy Lifetime Achievement Award.

Slash (musician)

Saul Hudson (born 23 July 1965), better known by his stage name Slash, is a British–American musician and songwriter. He is the lead guitarist of the American hard rock band Guns N' Roses, with whom he achieved worldwide success in the late 1980s and early 1990s. Slash has received critical acclaim and is considered one of the greatest guitarists in rock history.

In 1993, Slash formed the side project Slash's Snakepit; three years later he left Guns N' Roses in 1996 and co-founded the supergroup Velvet Revolver, which re-established him as a mainstream performer in the mid to late 2000s. Slash has released four solo albums: Slash (2010), featuring an array of guest musicians, and Apocalyptic Love (2012), World on Fire (2014) and Living the Dream (2018) recorded with his band, Myles Kennedy and the Conspirators. He returned to Guns N' Roses in 2016.

Time magazine named him runner-up on their list of "The 10 Best Electric Guitar Players" in 2009, while Rolling Stone placed him at number 65 on their list of "The 100 Greatest Guitarists of All Time" in 2011. Guitar World ranked his guitar solo in "November Rain" number 6 on their list of "The 100 Greatest Guitar Solos" in 2008, and Total Guitar placed his riff in "Sweet Child o' Mine" at number 1 on their list of "The 100 Greatest Riffs" in 2004. In 2010, Gibson Guitar Corporation ranked Slash as number 34 on their "Top 50 Guitarists of All Time", while their readers landed him number 9 on Gibson's "Top 25 Guitarists of All Time". In 2012, he was inducted into the Rock and Roll Hall of Fame as a member of Guns N' Roses' classic lineup.

Stevie Ray Vaughan

Stephen Ray Vaughan (October 3, 1954 – August 27, 1990) was an American musician, singer, songwriter, and record producer, and one of the most influential guitarists in the revival of blues in the 1980s. He is commonly referred to as one of, if not the greatest guitar player of all time.

Vaughan was born and raised in Dallas, Texas. He began playing guitar at the age of seven, inspired by his older brother Jimmie. He dropped out of high school in 1971 and moved to Austin the following year. He played gigs with numerous bands, earning a spot in Marc Benno's band the Nightcrawlers and later with Denny Freeman in the Cobras, with whom he continued to work through late 1977. He then formed his own group Triple Threat Revue, but he renamed them Double Trouble after hiring drummer Chris Layton and bassist Tommy Shannon. He gained fame after his performance at the Montreux Jazz Festival in 1982, and his debut studio album Texas Flood charted at number 38 in 1983, a commercially successful release that sold over half a million copies. He headlined concert tours with Jeff Beck in 1989 and Joe Cocker in 1990, but he died in a helicopter crash on August 27, 1990 at the age of 35. It was 36 days before his 36th birthday.

Vaughan received several music awards during his lifetime and posthumously. In 1983, readers of Guitar Player voted him Best New Talent and Best Electric Blues Guitar Player. In 1984, the Blues Foundation named him Entertainer of the Year and Blues Instrumentalist of the Year, and in 1987, Performance Magazine honored him with Rhythm and Blues Act of the Year. He won six Grammy Awards and ten Austin Music Awards and was inducted posthumously into the Blues Hall of Fame in 2000 and the Musicians Hall of Fame in 2014. Rolling Stone ranked him as the 12th greatest guitarist of all time. In 2015, Vaughan and Double Trouble were inducted into the Rock and Roll Hall of Fame.

Tom Morello

Thomas Baptiste Morello (born May 30, 1964) is an American musician, singer, songwriter, actor and political activist. He is best known for his tenure with the band Rage Against the Machine and then with Audioslave. As of 2019, Morello is a member of the supergroup Prophets of Rage. Morello was also a touring musician with Bruce Springsteen and the E Street Band. He is also known for his acoustic solo act, the Nightwatchman, and Street Sweeper Social Club.

He attended Harvard University and earned a Bachelor of Arts degree from the Committee on Degrees in Social Studies. After his previous band Lock Up disbanded, Morello met Zack de la Rocha, and the two founded Rage Against the Machine together, going on to become one of the most popular and influential rock acts of the 1990s.

He is best known for his unique and creative guitar playing style, which incorporates feedback noise, unconventional picking, effects, and tapping, as well as heavy use of guitar effects. Morello is also known for his leftist political views and activism; creating the Nightwatchman offered an outlet for his views while playing apolitical music with Audioslave. He was ranked number 40 in Rolling Stone magazine's list of the "100 Greatest Guitarists of All Time".

Van Halen

Van Halen is an American hard rock band formed in Pasadena, California, in 1972. From 1974 until 1985, the band consisted of guitarist Eddie Van Halen, vocalist David Lee Roth, drummer Alex Van Halen, and bassist Michael Anthony.The band went on to become major stars, and by the early 1980s they were one of the most successful rock acts of the time. 1984 was their most successful album. The lead single, "Jump", became an international hit and their only single to reach number one on the Billboard Hot 100. The following singles, "Panama" and "I'll Wait", both hit number 13 on the U.S. charts. The album went on to sell over 12 million copies in the U.S. alone. In 1985, the band replaced lead singer David Lee Roth with former Montrose lead vocalist Sammy Hagar. With Hagar, the group would release four U.S. number-one albums over the course of 11 years. Hagar left the band in 1996 shortly before the release of the band's first greatest hits collection, Best Of – Volume I. Former Extreme frontman Gary Cherone was quickly recruited as lead singer to replace Hagar, and Van Halen III was released in 1998. Cherone left the band in frustration in 1999 after the tour due to the poor commercial performance of the album.

Van Halen went on hiatus until 2003 when they reunited with Hagar for a worldwide tour. The reunited band released a second greatest hits collection the following year, The Best of Both Worlds. Like Volume I before it, The Best of Both Worlds included material from both the Roth and Hagar eras but omitted any Cherone era tracks. The album featured three brand new tracks recorded by the reunited band, two of which were released as singles. Hagar again left Van Halen in 2005, and in 2006 Roth returned as lead vocalist for their highest-grossing tour, and one of the highest-grossing tours of that year. Anthony was not invited to participate in the tour and was essentially fired from the band, replaced by Wolfgang Van Halen, Eddie's son. In 2012, the band released the commercially and critically successful, A Different Kind of Truth, with Roth as lead vocalist. According to the RIAA, Van Halen is the 19th-best-selling band/artist in United States history, selling 56 million albums in the U.S. They were also revealed at number 4 on the Billboard's top moneymakers list in 2013. Van Halen is one of only five rock bands that have had two studio albums sell more than 10 million copies in the U.S. Additionally, Van Halen charted 13 number-one hits in the history of Billboard's Mainstream Rock chart and they are one of the world's best-selling bands of all time, having sold more than 80 million records.Van Halen achieved worldwide fame for their many popular songs and larger-than-life stage performances; they also became known for the drama surrounding the departures of former members. Controversy surrounded the band following the exits of Roth, Hagar, and Anthony; this controversy often included numerous conflicting press statements between the former members and the band. In 2007, Van Halen was inducted into the Rock and Roll Hall of Fame. VH1 ranked them 7th on their list of the top 100 hard rock artists of all time.
