Concerto for Harpsichord, Flute and Violin in A minor, BWV 1044
Though this is a triple concerto, the harpsichord has the most prominent role and greatest quantity of material: there are several cadenzas and virtuosic passages; the scoring is identical to that of Brandenburg concerto no. 5, BWV. 1050, though the character is quite different. The first and third movements are adapted from the prelude and fugue in A minor for solo harpsichord, BWV. 894, which have been developed with added tutti sections. The middle movement is from the trio sonata for organ in Dm, BWV. 527, which has been expanded to four voices; only the solo instruments play, and the flute and violin share the melody and accompaniment, switching roles on the repeat of each half. It is scored for harpsichord solo, violin solo, flute solo, violin I/II, viola and continuo (cello, violone) and it lasts around 22 minutes.
