Doo-Wop is a style of vocal music that emerged in the 1940s and became popular in the 1950s. It features a group of singers harmonizing, often with a lead vocalist, and is characterized by its simple melodies and catchy rhythms. The genre often includes nonsensical syllables and repetitive phrases, creating a distinctive sound. The roots of Doo-Wop can be traced back to African American vocal traditions and rhythm and blues. Notable groups like The Platters and The Drifters helped popularize the genre, which has influenced many later styles of music, including Motown and R&B.
