He wrote a large amount of chamber music, including over one hundred string quintets for two violins, viola and two cellos (a type which he pioneered, in contrast with the then common scoring for two violins, two violas and one cello), a dozen guitar quintets, not all of which have survived, nearly a hundred string quartets, and a number of string trios and sonatas (including at least 19 for the cello). His orchestral music includes around 30 symphonies and 12 virtuoso cello concertos.
