House is a music genre characterized by a repetitive four-on-the-floor beat and a typical tempo of 120 beats per minute. It was created by DJs and music producers from Chicago's underground club culture in the early/mid 1980s, as DJs began altering disco songs to give them a more mechanical beat.

House was pioneered by African American DJs and producers in Chicago such as Frankie Knuckles, Ron Hardy, Jesse Saunders, Chip E., Joe Smooth, Steve "Silk" Hurley, Farley "Jackmaster" Funk, Marshall Jefferson, Phuture, and others. House music expanded to other cities such as London, then New York City and became a worldwide phenomenon.
