Barbershop is a style of music that has become one of the most recognizable both in and out of the music community. However, what makes a particular arrangement “barbershop” and not jazz, doowop, or any other form of acappella music? Technically, barbershop harmony is made up of four voices. Three of the voices harmonize to the melody, normally sung by the lead part. The tenor harmonizes above the lead, while the bass sings the lowest harmonizing notes. The baritone part provides ‘in-between’ notes, like the ‘barbershop’ seventh, that gives barbershop its original and rich sounds.
