Disco emerged in the late 1960s from genres like soul and funk. It became popular in dance clubs in the mid-1970s and was characterized by a dance-oriented pop sound. Key elements included vocals, a four-beat rhythm, and orchestral instruments. Popular performers included Donna Summer, Bee Gees, and Chic. Producers played an important role in developing the disco sound through techniques like remixing. Disco peaked in popularity in the late 1970s but then declined in the early 1980s, though it influenced later genres like house and techno.
