House is a genre of electronic dance music characterized by a repetitive four-on-the-floor beat and a typical tempo of 120-130 beats per minute as a re-emergence of 1970s disco.[11] It was created by DJs and music producers from Chicago’s underground club culture and evolved slowly in the early/mid 1980s as DJs began altering disco songs to give them a more mechanical beat.[1] By early 1988, House became mainstream and supplanted the typical 80s music beat.[12]
House was created and pioneered by 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 initially expanded internationally, to London, then to other American cities, such as New York City, and ultimately a worldwide phenomenon.[13]
