Barbershop specialty is a term used to describe the unique style of singing that is typically found in barbershop quartets. HARMONY is a key element of this style, which is characterized by four-part close HARMONY singing with a strong emphasis on the melody. The four parts are lead, tenor, baritone, and bass, and each part has its own distinct role in creating the overall sound. The lead sings the melody, the tenor harmonizes above the lead, the baritone harmonizes below the lead, and the bass provides the foundation for the group. This style of singing is often accompanied by a cappella singing, which is singing without any instrumental accompaniment.
