Chamber Music is traditionally music played by a small group of musicians (usually between three and nine players). The "chamber" refers to the practice, particularly common in the nineteenth century, of performing such music in a chamber (small hall) or room in order to do justice to the intimate character and finer nuances that characterize such music. Today the practice of performing such music in large concert halls is commonplace. There is no conductor involved in chamber music and the individual performers each play a solo part as opposed to an orchestra or band where a group of musicians may all play the same part. Experts in the field of classical music largely agree that chamber music is one of the most sophisticated forms of music because it requires a most delicate sense of ensemble work as well as superior musicality of all the individuals involved.
