Barbershop quartets

A barbershop quartet is a vocal ensemble of four singers who harmonize a cappella, meaning without instrumental accompaniment. They typically sing in four parts: lead, tenor, baritone, and bass, creating a rich, full sound with precise harmony. Their style emphasizes a "ringing" chord quality, blending voices seamlessly to produce a warm, resonant tone. Originating from early 20th-century American barber shops, these groups perform popular songs with a focus on vocal skill, tight harmonies, and dynamic expression, often engaging audiences with their lively performances and nostalgic musical style.
