Reductionism is a strand of experimental and improvised music that pursues extreme restraint, quiet dynamics, and a focus on micro‑sound. Rather than foregrounding melody, harmony, or steady pulse, it prioritizes timbre, texture, and the audibility of small gestures, room tone, and silence.
Performances typically unfold at very low volumes with sparse events and long stretches of near‑inaudibility. Players use extended techniques, feedback, contact microphones, inside‑piano preparations, sine tones, and no‑input mixers to reveal subtle sonic details. Silence is treated as musical material, and the performance space itself becomes part of the instrument.
The result is a heightened, forensic listening situation in which the smallest action—bow hair noise, cable hum, breath through a mouthpiece—can reorganize the entire sound field.

Reductionism arose in the late 1990s from intersections of free improvisation and electroacoustic practice. Musicians in Berlin, London, and Tokyo began to pursue radically quiet, sparse, and timbre‑centric improvisation, reacting against gestural free jazz exuberance and against formalist minimalism by stripping materials to micro‑events and silence.
Reductionism treats silence as an active material, foregrounds environmental sound, and favors near‑static forms with long durations. It commonly uses no‑input mixing boards, contact mics, sine‑wave oscillators, and fragile instrumental noises. The aesthetic encourages very low dynamics and defers “virtuosic display” in favor of disciplined listening and small, consequential gestures.
Through specialist labels, small venues, and festivals, the approach spread internationally during the 2000s. It influenced lowercase, informed strands of electroacoustic improvisation, and permeated parts of sound art and microsound culture. While sometimes criticized as austere or exclusionary, it had a lasting impact on how improvisers, composers, and listeners conceive silence, space, and attention in music.
