Reductionism is a form of improvised music that developed towards the end of the 20th century, centered in Berlin, London, Tokyo, and Vienna.
[1] The key characteristics of the music include microtonality, extended techniques, very soft and quiet dynamics, silence, and unconventional sounds and timbres.
[1] Some of the names associated with reductionism are Radu Malfatti,[2] Toshimaru Nakamura, Axel Dörner and Rhodri Davies.
The London-based movement has been described as New London Silence.
