Bach Cello Suite no. 3 in C major, BWV 1009

The Prelude of this suite consists of an A–B–A–C form. The Allemande is the only movement in the suites that has an up-beat consisting of three semiquavers instead of just one, which is the standard form. The second Bourrée, though in C minor, has a 2-flat key-signature. This notation, common in pre-Classical music, is sometimes known as a partial key-signature. The first and second Bourrée of the third suite is sometimes used as solo material for other bass instruments such as the tuba, euphonium, trombone and bassoon.
