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
Brandenburg Concertos of a trio sonata for two violas and continuo, although the cello has a decorated version of the continuo bass line. In the last movement, the spirit of the gigue underlies everything, as it did in the finale of the fifth concerto. Because King Frederick William I of Prussia was not a significant patron of the arts, Christian Ludwig seems to have lacked the musicians in his Berlin ensemble to perform the concertos. The full score was left unused in the Margrave's library until his death in 1734, when it was sold for 24 groschen (as of 2014, about US$24)
