Originally for 2 Clarinets and Bassett Horn. From editor/arranger William Conable: “Starting around 1783 Mozart became friends with the virtuoso clarinetist Anton Stadler (1753-1812) and wrote a number of pieces for him, including the clarinet concerto and the the clarinet quintet. It can be assumed that the 5 divertimenti for two clarinets and basset horn, of which this is the first, were written for him and his brother Johann (also a clarinetist), as well as the Adagio, which was probably a Masonic ritual piece. Both of these works sound very good for cello ensemble. The parts vary in difficulty: the lower parts are relatively easy, while the upper ones can be quite challenging.”
