Decay Music

Reductionism is a strand of experimental, improvised music that emerged in the late 1990s, coalescing in scenes around Berlin, London, Tokyo, and Vienna. It focuses on extremely quiet dynamics, the creative use of silence, and the cultivation of subtle, unconventional timbres. Hallmarks include microtonality, extended and non-standard techniques, high amplification at very low volumes, and attention to minute sonic events such as friction, breath, electrical hum, and resonant artifacts. Rather than narrative arcs or traditional rhythm/harmony, the music prioritizes space, texture, and the act of listening itself.

Process music is a movement in which a composition is generated by a clearly defined procedure or rule-set. Sometimes this procedure is made audible—so the listener can follow the gradual changes as they unfold—and sometimes the process remains hidden behind the surface of the sound. Typical processes include phasing (two identical patterns drifting out of sync), additive or subtractive procedures (expanding or contracting a pattern by fixed steps), iterative feedback (repeating an operation so the output becomes the next input), permutations, stochastic or probabilistic rules, or instruction-based performance systems. The aesthetic ranges from hypnotic and pulse-driven to fragile and static, but the core idea remains: the music arises from the process.
