Clarinet–viola–piano trio
A clarinet–viola–piano trio, often titled "Trio for Clarinet, Viola and Piano" is a work of chamber music that is scored for clarinet, viola, and piano; or is the designation for a musical ensemble of a group of three musicians playing these instruments. This combination of instruments differs from other combinations, as the viola and the clarinet share approximately the same musical range, but not the same tone quality. The Austrian composer Wolfgang Amadeus Mozart was the first to write for this combination of instruments with his "Kegelstatt" Trio, K. 498 (1786). which helped to popularize the clarinet in classical music. 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. Description
A clarinet–viola–piano trio, or trio for clarinet, viola and piano is a work of chamber music written for a musical ensemble consisting of a viola player (or violist), a clarinettist, and pianist. The term clarinet, viola and piano trio is also used as a description of these musicians. This combination of instruments differs from the traditional piano trio instrumentation—for piano, violin and violoncello—and other combinations, such as for clarinet–violin–piano trio and the clarinet–cello–piano trio, as the viola and the clarinet share roughly the same musical range. 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'. The Austrian composer Wolfgang Amadeus Mozart was the first to write for this combination of instruments with his "Kegelstatt" Trio, K. 498 (1786). Mozart's Trio, along with his Clarinet Quintet, K. 581 (1789) and Clarinet Concerto, K. 622 (1791), were written when the clarinet was a relatively newly invented instrument. The three compositions featured the clarinet and were responsible for popularizing the instrument's use in chamber and orchestral works. German composers Robert Schumann (1810–1856) and Max Bruch (1838–1920) also wrote for the clarinet, viola and piano. Repertoire

Trios from concertos for viola or clarinet 
Although not originally intended as a chamber music work, the works of several composers who have written concerti for viola and clarinet have been arranged for a trio with the orchestral part condensed and arranged for piano. Notably, the Double Concerto for viola, clarinet and orchestra, Op. 88 (1911) of Max Bruch has been arranged for viola, clarinet and piano. Other concertos with these solo instruments include a concerto by Aulis Sallinen and Alternatim (1997) by Luciano Berio. Transcriptions
