A chamber orchestra is a small ensemble of musicians that typically consists of 10 to 40 members. Synonyms for the term include small orchestra, mini orchestra, and pocket orchestra. Other options include string ensemble, string orchestra, and string quartet. The term "chamber" refers to the fact that the group is small enough to perform in a chamber or small room, rather than requiring a large concert hall like a full-sized symphonic orchestra. Some other possible synonyms include ensemble, consort, and band. Regardless of the name or size, a chamber orchestra is known for playing beautiful music with precision and artistry.
