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
Horn Concertos (Mozart) Horn Concertos (Mozart) The Horn Concertos by Wolfgang Amadeus Mozart were written for his friend Joseph Leutgeb whom he had known since childhood. Leutgeb was a skilled player, as the works are very difficult to perform on the natural horn of the period, requiring lip trills, much hand-stopping, and rapid tonguing. In addition to the four works listed above, there are two incomplete concerto movements, K. 370b and the Concert Rondo, K. 371, both from 1781 and both in E-flat major, and a 91-bar fragment of the first movement for a concerto in E major (K. 494a), written in 1785
