Principal (music)

The principal musician in an orchestra or other large musical ensemble is the leader of the group of musicians playing that instrument. Every instrumental group (or section) has a principal who is generally responsible for leading the group and playing orchestral solos. The violins are divided into two groups, first violin and second violin, each with its principal. The principal first violin is called the concertmaster (or "leader" in the UK) and is considered the leader of not only the string section, but of the entire orchestra, subordinate only to the conductor and the chamber tone (A natural) of the principal oboe, who tunes the orchestra and is responsible for general intonation.
