Music not intended for the church, theatre, or concert hall. Now it generally implies a performing group of small size. The Italian is musica da camera; the German, Kammermusik. Schubert's "Trout" Quintet is an example of chamber music.
Music written for a small number of musicians, such as a string quartet, to be played in a room rather than a concert hall.
Music played by small ensembles, such as a string quartet, with one performer to a part.
