BWV 1059 is a fascinating fragment of a harpsichord concerto by Johann Sebastian Bach. The existing material consists of just the first 10 measures of the first movement. Scholars believe this concerto is likely a reworking of a lost oboe concerto, as its material was later reused by Bach in movements of his Cantata BWV 35. The key of D minor and the concerto's structure are typical of Bach's mature instrumental style from his time in Leipzig.
An incomplete harpsichord concerto reconstructed using movements from Cantata BWV 35, reflecting Bach's reuse of material across sacred and secular works.
