Clarinet–violin–piano trio

A clarinet–violin–piano trio is a standardized chamber musical ensemble made up of one clarinet, one violin, and one piano participating in relatively equal roles, or the name of a piece written for such a group. An example of a clarinet–viola–piano trio existed several hundred years before the clarinet–violin–piano trio; Mozart composed the Kegelstatt Trio in the 18th century, and the Romantic composer Max Bruch composed a suite of eight pieces for this combination, as well as a double concerto for viola, clarinet, and orchestra.
