Stamitz wrote symphonies, symphonies concertantes, and concertos for clarinet, cello, flute, oboe, bassoon, basset horn, violin, viola, viola d'amore and different combinations of these instruments. Some of his clarinet and viola concertos are particularly admired. He also wrote duos, trios and quartets. Two operas, "Der verliebte Vormund" and "Dardanus", are now lost. Stylistically, his music resembles that of Mozart or Haydn and is characterized by appealing melodies, although his writing for the solo instruments is not excessively virtuosic. The opening movements of his orchestral works, which are in sonata form, are generally followed by expressive and lyrical middle movements and final movements in the form of a rondo.
