Brandenburg Concertos Piccolo concertato, 2 Violini, una Viola col Basso Continuo. "Instrumentation": two corni da caccia (natural horns), three oboes, bassoon, violino piccolo, two violins, viola, cello, basso continuo "Duration": about 22 minutes This concerto is the only one in the collection with four movements. The concerto also exists in an alternative version, Sinfonia BWV 1046a, which appears to have been composed during Bach's years at Weimar. The Sinfonia, which lacks the third movement entirely, and the Polacca from the final movement, appears to have been intended as the opening of the cantata "Was mir behagt, ist nur die muntre Jagd", BWV
Organ concertos, Op. 4 (Handel) of his oratorios Esther and Athalia. During this period Handel prepared the 16 movements of the four organ concertos HWV 290-293, of which 10 are reworkings of previous compositions with the remaining 6 largely newly composed. HWV 292, completed in March 1735, contains the most new material, although even there the ritornello of the first movement is a borrowing from Act 1 of Alcina. It featured in the April performances of Athalia at Covent Garden. The other concertos were first heard in March, HWV 290 and 291 in Esther and HWV 293 in Deborah. Handel completed Alexander's Feast in January
