  • "The director of a chorus or an orchestra; one who indicates to the performers the rhythm and the expression of a piece of concerted music by means of motions of the hands or of a baton. The office of conductor in the modern sense was not clearly distinguished from that of leader until about 1800; formerly the leader played an instrument, usually the harpsichord."
