Big beat is an electronic music genre that usually uses heavy breakbeats and synthesizer-generated loops and patterns – common to acid house/techno. The term has been used by the British music industry to describe music by artists such as The Prodigy, the Chemical Brothers, Fatboy Slim, the Crystal Method, Propellerheads, Basement Jaxx and Groove Armada.

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.
