Barbershop is a four-part, a cappella vocal harmony style built around a lead melody with tenor, baritone, and bass parts that lock chords to create "ringing" overtones. Its hallmark sound emphasizes dominant-seventh-rich harmony, homophonic textures, and expressive devices such as swipes, echoes, and tag endings. The repertoire traditionally draws on late-19th- and early-20th-century American popular songs, with lyrical themes that are romantic, sentimental, or humorous. Performance values center on unified vowels, precise tuning (often approaching just intonation), balanced resonance, and coordinated interpretation.
