chamber music, music composed for small ensembles of instrumentalists. In its original sense, chamber music referred to music composed for the home, as opposed to that written for the theatre or church. Since the “home”—whether it be drawing room, reception hall, or palace chamber—may be assumed to be of limited size, chamber music most often permits no more than one player to a part. It usually dispenses with a conductor. Music written for combinations of stringed or wind instruments, often with a keyboard (piano or harpsichord) as well, and music for voices with or without accompaniment have historically been included
