Acid house is a subgenre of house music developed around the mid-1980s by DJs from Chicago. The style is defined primarily by the squelching sounds and basslines of the Roland TB-303 electronic bass synthesizer-sequencer, an innovation attributed to Chicago artists Phuture and Sleezy D circa 1986.

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. It originated in the Black queer community in Chicago. 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. By early 1988, House became mainstream and supplanted the typical 80s music beat.
