A baritone is a type of classical male singing voice whose vocal range lies between the bass and the tenor voice-types. The term originates from the Greek βαρύτονος (barýtonos), meaning "heavy sounding". Composers typically write music for this voice in the range from the second F below middle C to the F above middle C (i.e. F2–F4) in choral music, and from the second A below middle C to the A above middle C (A2 to A4) in operatic music, but the range can extend at either end. Subtypes of baritone include the baryton-Martin baritone (light baritone), lyric baritone, Kavalierbariton, Verdi baritone, dramatic baritone, baryton-noble baritone, and the bass-baritone.
