A piano sextet is a composition for piano and five other musical instruments, or a group of six musicians who perform such works. There is no standard grouping of instruments with that name, and compared to the string quartet or piano quintet literature, relatively few such compositions exist. The best-known piano sextet is probably Chausson's Concert, widely regarded as one of the masterpieces of the French chamber music literature (for example, the critic Jean Gallois describes it as "superb").
The following is an incomplete list of piano sextet composers and their works in this genre:
Ernest Chausson (1855–1899), Concert in D major, Op. 21, composed 1891, for piano, violin, and string quartet
Aaron Copland (1900–1990), Sextet, composed 1938, for piano, clarinet, and string quartet
Ernő Dohnányi (1877–1960), Sextet for string trio, clarinet, horn, and piano
Louise Farrenc (1804–1875), Sextet in C minor, op. 40, for piano and wind quintet
