This is one of Mozart’s longest and grandest concerti, and some of the writing could be said to pre-empt his 39th Symphony.
It is one of the pieces where he starts to use clarinets in place of oboes. The opening movement is strong, with a charming triad/octave figure in sequence with suspensions – you can see Mozart playing with the orchestration. There’s a real sense of dialogue between orchestra and soloist, and between wind and strings.
The second movement is similar to other slow movements in C minor by Mozart, and the final movement is a rondo that has the feel of the horn concerti and perhaps the more amusing of Mozart’s opera arias.
