Acid music is an umbrella term for electronic dance music styles that revolve around the distinctive "acid" timbre of the Roland TB‑303 bass synthesizer. Its hallmark is a twisting, resonant, and "squelching" bassline shaped by real‑time manipulation of the filter cutoff, resonance, accent, and slide. Emerging from the mid‑1980s Chicago house scene, acid rapidly propagated into related strains—most notably acid house, acid techno, acid trance, and acid breaks—while its 303 aesthetic seeped into broader techno and trance. The sound is minimalist but hypnotic: looping patterns, four‑to‑the‑floor drums, and evolving filter movements designed to induce dance‑floor trance. Culturally, acid music is inseparable from the DIY ethos of early house, iconic Chicago labels like Trax and DJ International, and pivotal artists such as Phuture. Its psychedelic name references the squelchy, mind‑bending quality of the 303 rather than any specific lyrical topic.
