The Onkyo music movement or Onkyokei (音響系 Onkyōkei) (translation: "reverberation of sound") is a form of free improvisation, emerging from Japan in the late 1990s. Onkyō (translation: "sound, noise, echo") places much more emphasis on sound texture than on musical structure, distilling elements of techno, noise, and electronic music into a unique hybrid. The Off Site, a venue in Tokyo, is home to the Onkyo music movement, which is characterized by improvisation, minimalism, and "quiet noise". Onkyo improvisation, "explores the fine-grained textural details of acoustic and electronic sound".
