Clarinet–viola–piano trio

The Austrian composer Wolfgang Amadeus Mozart was the first to write for this combination of instruments with his "Kegelstatt" Trio, K. 498 (1786).

German composers Robert Schumann and Max Bruch also wrote early pieces for the clarinet, viola and piano; the combination has been increasingly written for during the modern era.

The combination of viola and clarinet is distinguished by the tone quality of the instruments rather than by the register (i.e. the height of the pitch), as with a violin compared with a 'cello'.

German composers Robert Schumann (1810–1856) and Max Bruch (1838–1920) also wrote for the clarinet, viola and piano.

Works scored for clarinet, viola, and piano have gained increasing popularity in the modern era.
