Chorale cantata (Bach)

There are 52 chorale cantatas by Johann Sebastian Bach surviving in at least one complete version. Around 40 of these were composed during his second year as Thomaskantor in Leipzig, which started after Trinity Sunday 4 June 1724, and form the backbone of his chorale cantata cycle. The eldest known cantata by Bach, an early version of Christ lag in Todes Banden, BWV 4, presumably written in 1707, was a chorale cantata. The last chorale cantata he wrote in his second year in Leipzig was Wie schön leuchtet der Morgenstern, BWV 1, first performed on Palm Sunday, 25 March 1725. In the ten years after that he wrote at least a dozen further chorale cantatas and other cantatas that were added to his chorale cantata cycle.

Lutheran hymns, also known as chorales, have a prominent place in the liturgy of that denomination. A chorale cantata is a church cantata based on a single hymn, both its text and tune. Bach was not the first to compose them, but for his 1724-25 second Leipzig cantata cycle he developed a specific format: in this format the opening movement is a chorale fantasia on the first stanza of the hymn, with the hymn tune appearing as a cantus firmus. The last movement is a four-part harmonisation of the chorale tune for the choir, with the last stanza of the hymn as text. While the text of the stanzas used for the outer movements was retained unchanged, the text of the inner movements of the cantata, a succession of recitatives alternating with arias, was paraphrased from the inner stanzas of the hymn.

Chorale cantata cycle

Johann Sebastian Bach's chorale cantata cycle is the year-cycle of church cantatas he started composing in Leipzig from the first Sunday after Trinity in 1724. It followed the cantata cycle he had composed from his appointment as Thomaskantor after Trinity in 1723.

Bach's second cantata cycle is commonly used as a synonym for his chorale cantata cycle, but strictly speaking both cycles overlap only for 40 cantatas. Two further chorale cantatas may belong to both cycles: the final version of Christ lag in Todes Banden, BWV 4, and the earliest version of Ein feste Burg ist unser Gott, BWV 80; it is, however, uncertain whether these versions were first presented in Bach's second year in Leipzig. Bach composed a further 13 cantatas in his second year at Leipzig, none of them chorale cantatas, although two of them became associated with the chorale cantata cycle. After his second year in Leipzig, he composed at least eight further cantatas for inclusion in his chorale cantata cycle.

Around the start of the Bach Revival in the 19th century, almost no manuscripts of Bach's music remained in St. Thomas in Leipzig, apart from an incomplete chorale cantata cycle. In Leipzig the chorale cantatas were, after the motets, the second most often performed compositions of Bach between the composer's death and the Bach Revival. Philipp Spitta, in his 19th-century biography of the composer, praised the chorale cantatas, but failed to see them as a cycle tied to 1724–25. It took about a century after Spitta before Bach's cantata cycles were analysed in scholarly literature, but then Bach's ambitious project to write a chorale cantata for each occasion of the liturgical year was characterized as "the largest musical project that the composer ever undertook".


The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Dutch–German–Polish physicist Daniel Gabriel Fahrenheit (1686–1736). It uses the degree Fahrenheit (symbol: °F) as the unit. Several accounts of how he originally defined his scale exist. The lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from equal parts of ice, water and salt (ammonium chloride). Further limits were established as the melting point of ice (32 °F) and his best estimate of the average human body temperature (96 °F, about 2.6 °F less than the modern value due to a later redefinition of the scale). The scale is now usually defined by two fixed points: the temperature at which water freezes into ice is defined as 32 °F, and the boiling point of water is defined to be 212 °F, a 180 °F separation, as defined at sea level and standard atmospheric pressure.

At the end of the 2010s, Fahrenheit was used as the official temperature scale only in the United States (including its unincorporated territories), its freely associated states in the Western Pacific (Palau, the Federated States of Micronesia and the Marshall Islands), the Bahamas, the Cayman Islands and Liberia. Antigua and Barbuda and other islands which use the same meteorological service, such as Anguilla, the British Virgin Islands, Montserrat and Saint Kitts and Nevis, as well as Bermuda, Belize and the Turks and Caicos Islands, use Fahrenheit and Celsius. All other countries in the world officially now use the Celsius scale, named after Swedish astronomer Anders Celsius.

Jantar Mantar, New Delhi

Jantar Mantar is located in the modern city of New Delhi. It consists of 13 architectural astronomy instruments. The site is one of five built by Maharaja Jai Singh II of Jaipur, from 1723 onwards, as he was given by Mughal emperor Muhammad Shah the task of revising the calendar and astronomical tables. There is a plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was placed there in 1910 mistakenly dating the construction of the complex to the year 1710. Later research, though, suggests 1724 as the actual year of construction. It's height is 723ft(9.039in)

The primary purpose of the observatory was to compile astronomical tables, and to predict the times and movements of the sun, moon and planets. Some of these purposes nowadays would be classified as astronomy.

Completed in 1724, the Delhi Jantar Mantar had decayed considerably by 1867. The Ram Yantra, the Samrat Yantra, the Jayprakash Yantra and the Mishra Yantras are the distinct instruments of Jantar Mantar.

List of Bach cantatas

This is a sortable list of the Bach cantatas, the cantatas of Johann Sebastian Bach. Bach's almost 200 extant cantatas are among his important vocal compositions.

The list includes both extant cantatas and, as far as known, lost cantatas. It is sortable by the cantata number which equals the number in the Bach-Werke-Verzeichnis (BWV), by title, by occasion during the liturgical year, the year of composition and date of first performance, as far as known. The scoring is provided, grouped by singers and groups of instruments. Colouring shows which cantatas are not extant church cantatas and which works were not even composed by Bach, but attributed to him in the past. A link to the free score of the Bach Gesellschaft in the International Music Score Library Project (IMSLP) is provided if available.

Louis I of Spain

Louis I (Luis Felipe; 25 August 1707 – 31 August 1724) was King of Spain from 15 January 1724 until his death in August the same year. His reign is one of the shortest in history, lasting for just over seven months.

Solar eclipse of May 22, 1724

A total solar eclipse occurred on May 22, 1724. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide.
