Barbershop vocal harmony as codified during the barbershop revival era (1930s–present) is a style of a cappella or unaccompanied vocal music characterized by consonant four-part chords for every melody note in a predominantly homophonic texture. Each of the four parts has its own role: generally the lead sings the melody the tenor harmonizes above the melody the bass sings the lowest harmonizing notes and the baritone completes the chord usually below the lead.
