Pachelbel's Canon (also known as the Canon in D, P 37) is an accompanied canon by the German Baroque composer Johann Pachelbel. The canon was originally scored for three violins and basso continuo and paired with a gigue, known as Canon and Gigue for 3 violins and basso continuo. Both movements are in the key of D major. Although a true canon at the unison in three parts, it also has elements of a chaconne. Neither the date nor the circumstances of its composition are known (suggested dates range from 1680 to 1706), and the oldest surviving manuscript copy of the piece dates from 1838 to 1842. Like his other works, Pachelbel's Canon went out of style, and remained in obscurity for centuries. A 1968 arrangement and recording of it by the Jean-François Paillard chamber orchestra gained popularity over the next decade, and in the 1970s the piece began to be recorded by many ensembles; by the early 1980s its presence as background music was deemed inescapable. From the 1970s onward, elements of the piece, especially its chord progression, were used in a variety of pop songs. Since the 1980s, it has also found increasingly common use in weddings and funeral ceremonies in the Western world. Creation In his lifetime, Pachelbel was renowned for his organ and other keyboard music, whereas today he is also recognized as an important composer of church and chamber music. Little of his chamber music survives, however. Only —a collection of partitas published during Pachelbel's lifetime—is known, apart from a few isolated pieces in manuscripts. The Canon and Gigue in D major is one such piece. A single 19th-century manuscript copy of them survives, Mus.MS 16481/8 in the Berlin State Library. It contains two more chamber suites. Another copy, previously in Hochschule der Künste in Berlin, is now lost. The circumstances of the piece's composition are wholly unknown. Hans-Joachim Schulze, writing in 1985, suggested that the piece may have been composed for Johann Christoph Bach's wedding, on 23 October 1694, which Pachelbel attended. Johann Ambrosius Bach, Pachelbel, and other friends and family provided music for the occasion.<ref name = "Schulze, Hans-Joachim 1721">{{cite journal|last=Schulze|first= Hans-Joachim|author-link=Hans-Joachim Schulze|title=Johann Christoph Bach (1671–1721) Organist and Schul Collega in Ohrdruf, Germany, Johann Sebastian Bachs erster Lehrer|journal=Bach-Jahrbuch|volume= 71 |year=1985|page= 70, footnote 79}}</ref> Johann Christoph Bach, the oldest brother of Johann Sebastian Bach, was a pupil of Pachelbel.
