The Partita in D minor for solo violin (BWV 1004) by Johann Sebastian Bach was written between 1717 and 1720. It is a part of his compositional cycle called Sonatas and Partitas for Solo Violin.
The partita contains five movements, given in Italian as:
The movements correspond to the dances of the time, and they are frequently listed by their French names: Allemande, Courante, Sarabande, Gigue, and Chaconne. The final movement is written in the form of variations, and lasts approximately as long as the first four movements combined.
Performance time of the whole partita varies between 26 and 32 minutes, depending on the approach and style of the performer.
Professor Helga Thoene suggests that this partita, and especially its last movement, was a tombeau written in memory of Bach's first wife, Maria Barbara Bach (who died in 1720), though this theory is controversial.
Yehudi Menuhin called the Chaconne "the greatest structure for solo violin that exists".
Violinist Joshua Bell has said the Chaconne is "not just one of the greatest pieces of music ever written, but one of the greatest achievements of any man in history. It's a spiritually powerful piece, emotionally powerful, structurally perfect." He played the piece busking in L'Enfant Plaza for The Washington Post.
Since Bach's time, several transcriptions of the piece have been made for other instruments, particularly for the piano (by Ferruccio Busoni and Joachim Raff), and for the piano left-hand (by Brahms).
