This newly composed material, which recurs throughout the movement, creates a contrast with that of the soloists, much of which is directly drawn from the original prelude, especially the harpsichord part. Like the first movement of Brandenburg Concerto No. 5, the virtuosic harpsichord part takes precedence, with some passages from the original extended, some played solo and some omitted. In the solo episodes the flute and violin provide a "small ripieno" accompaniment to the harpsichord, contrasting with the "large ripieno" of the orchestral strings in the "tutti" sections.
