Barbershop music, with its close unaccompanied four-part harmonies and ringing chords, is an American folk art that has found its way around the world. Barbershop harmony’s four voice parts are still called by their traditional names – tenor, lead, baritone and bass – whether referring to men’s or women’s vocal groups. One of the distinctive qualities of barbershop harmony is that the melody, sung by the lead voice, is below the tenor harmony.
