Definition of Acid house

Acid house is an electronic music-oriented subgenre of house music, which emphasizes a repetitive, hypnotic and trance-like style, with samples or spoken lines rather than sung lyrics. Acid house's characteristic electronic "squelch" sounds were developed by mid-1980s DJs who were experimenting with the Roland TB-303 electronic synthesizer-sequencer. Acid house spread to the United Kingdom, Australia and continental Europe where it was played by DJs in the early rave scene. By the late 1980s, copycat tracks and acid house remixes brought the style into the mainstream, where it influenced other pop and dance styles.
