Doowop music is a genre that emerged in the 1940s and became popular in the 1950s and early 1960s. It is characterized by vocal harmonies, simple melodies, and a strong rhythm. Groups often performed a cappella or with minimal instrumental accompaniment, creating a unique sound that highlighted their vocal abilities. The lyrics of doowop songs typically focus on themes of love and relationships. Notable doowop groups include The Platters, The Drifters, and The Five Satins. This genre laid the groundwork for later styles of music, influencing rock and roll and rhythm and blues.
