Squelching 303s and hypnotic beats ignite the dancefloor. 122–133 BPM.
Acid House is a subgenre of house music that emerged in Chicago in the mid-1980s. It is characterized by the repetitive, squelching sound of the Roland TB-303 bass synthesizer, often combined with a 4/4 drum machine beat and hypnotic vocals or samples. The genre was pivotal in the development of rave culture and electronic dance music.

The classic anthems and current essentials that define Acid House.
Acid House is characterized by a driving, repetitive 4/4 beat with a prominent kick drum on every beat, hi-hats on the off-beats, and a clap or snare on beats 2 and 4. The signature element is the squelching, resonant, and often distorted sound of the Roland TB-303 bass synthesizer, which is programmed with sliding notes and accent patterns to create a hypnotic, psychedelic effect. The overall sound is minimal, raw, and energetic, with occasional vocal samples or spoken word snippets adding to the atmosphere.
Acid House originated in Chicago, USA, around 1984, pioneered by DJs and producers like Phuture, who first used the Roland TB-303 bass synthesizer to create a distinctive squelching sound. The genre quickly spread to the UK, where it became synonymous with the late-1980s 'Second Summer of Love' and the rise of rave culture.
Musically, Acid House is built on a 4/4 kick drum pattern, off-beat hi-hats, and a snare or clap on beats 2 and 4. The TB-303 is the star, programmed with resonant, sliding, and accent patterns that create a hypnotic, psychedelic effect. Vocals are often sparse, consisting of sampled phrases or spoken word, and the overall vibe is repetitive and trance-inducing.
Culturally, Acid House represented a shift towards a more inclusive, hedonistic party scene, emphasizing unity and peace (PLUR). It also sparked a fashion and drug culture (notably MDMA) that defined the late 80s and early 90s. The genre's influence is immense, laying the groundwork for techno, trance, and modern electronic music.
How Acid House is built — drum pattern, swing, and the sounds you need.
To produce Acid House, start with a simple 4/4 drum pattern using a Roland TR-808, TR-909, or similar drum machine. Keep the kick on every beat, hi-hats on eighth notes, and a clap on beats 2 and 4. Add a TB-303 or emulation for the bassline; program it with a repetitive pattern, using the accent, slide, and filter controls to create the characteristic squelch. Use a low-pass filter with resonance to shape the sound. Keep the arrangement minimal, with subtle changes every 8 or 16 bars. Add occasional vocal samples or synth stabs for variation. The BPM should be around 125-130. Swing is minimal; the feel is straight and driving.
