The different types of orchestras include chamber orchestra, symphony orchestra, and philharmonic orchestra. An orchestra contains string, woodwind, brass, and percussion instruments. A chamber orchestra typically has fewer than fifty musicians. An orchestra is directed by a conductor although some modern orchestras do not use a conductor. The early history of orchestras can be traced back to Ancient Egypt which were groups of musicians that gathered for funerals, holidays, or festivals. Well known orchestras include the New York Philharmonic, London Philharmonic, and the London Symphony.
