Bach's Partita BWV 1013 is a wonderful unaccompanied work and was, in all likelihood, written for the Transverse Flute, though that is by no means certain. In fact, there is an earlier version of the Allemande for a keyboard or stringed instrument. The Partita, originally in the key of A minor has been transposed down into G minor, putting it into a perfect range for Tuba or Bass Trombone. The work is in four movements: Allemande, Corrente, Sarabande and Bourrée Anglaise and is appropriate for advanced performers.
