The Partita in A minor, BWV 1013, is a work for solo flute composed by Johann Sebastian Bach. It spans four movements and its composition date has been speculed to be in the first half of the 1720's (according to research work done on the manuscripts and an analysis of the complexity of the piece). The piece was discovered in 1917 and titled 'Partita' by editors, though the only surviving manuscript bears the title "Solo p[our une] flûte traversière par J. S. Bach".
