Barbershop Harmony is a unique style of a cappella singing that emphasizes four-part vocal harmony. It originated in the late 19th century in the United States, where singers would gather in barbershops to entertain each other. The music typically features a lead singer, a tenor, a baritone, and a bass, creating rich, resonant chords that are pleasing to the ear. This genre is characterized by its close harmonies and often upbeat, nostalgic songs. Barbershop quartets and choruses perform at competitions and community events, celebrating camaraderie and the joy of singing together. The style has a timeless appeal, bringing people together through music.
