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 G below middle C to the G above middle C (G₂ to G₄) 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.
