Clarinet trio
A clarinet trio is a chamber musical ensemble that consists of a clarinet and two other instruments. Most commonly, the clarinet is combined with a piano and a bowed string instrument, such as a viola, a cello or a violin. In Western classical music, the clarinet-viola-piano trio, clarinet-cello-piano trio and clarinet-violin-piano trio have proven most popular, but many other combinations exist, with or without piano. A musical work for any of these ensembles is also called a clarinet trio.
