The Bop-Chords were an American doo-wop group from Harlem, New York, active in the mid-1950s. Known for their distinctive harmonious style, they were led by Ernest Harriston, who later changed his name to Ernest Warren, and included William Dailey, Ken Hamilton, Leon Ivey, and Morris Smarr. Their most influential work, "Castle in the Sky," remains a classic example of the doo-wop genre. Despite their short-lived career, the Bop-Chords made a significant contribution to the development and popularity of doo-wop music.
