Barbershop harmony is a style of unaccompanied singing with three voices harmonizing to the melody. The lead sings the melody; the tenor harmonizes above the lead; the bass sings the lower harmonizing notes; the baritone provides in-between notes, either above or below the lead to make dominant-type chords ("barbershop sevenths"). This arrangement of voices gives barbershop a distinctive, full sound.
