Chamber Music America defines chamber music as music for small ensembles in which players perform one to a part, generally without a conductor.

Historically, the term chamber music was restricted to Western classical music for small ensembles, such as the string quartet. Today, however, chamber music comprises many different musical styles and genres.

At the heart of this art form is a spirit of collaboration. Democratic in essence, chamber music demands that each individual engage in a close musical dialogue with the other performers. Their collective musical instinct, experience, knowledge, and talent guide the process of interpreting, rehearsing, and performing.
