Violin Concerto no. 2 in E major, BWV 1042

The E major concerto also exists as a harpsichord concerto in D, BWV 1054, one of the arrangements Bach made in Leipzig in the 1730s; the violin version is the original. Its first movement uses an almost symmetrical da capo design rare in the concerto literature of the period, and its slow movement is a passacaglia — the bass line repeats unchanged beneath the solo violin from beginning to end. The finale is a rondo, the only one in Bach's surviving concertos.
