Violin Concerto in E major (Bach)

The 'Violin Concerto in E major, BWV 1042, by Johann Sebastian Bach is a concerto for violin, strings, and continuo in three movements:

1. Allegro, meter of , with ritornello.
2. Adagio, meter of 3
   4, with a ground bass.
3. Allegro assai, meter of 3
   8, with an overall structure of a rondo.

While there are two 18th-century scores, neither is autographed; however, Bach re-used the concerto as the model for his Harpsichord Concerto in D major, BWV 1054, found in his 1737–39 autographed manuscript of these works. The concerto is thought to have been written early in Bach's time in Weimar, when he was Konzertmeister at the Ducal Court.
