Onkyo (also called onkyō-kei) is a Japanese approach to experimental, electroacoustic improvisation that centers on extremely quiet dynamics, sparse gestures, and the amplification of minute sonic events. Rather than focusing on melody, harmony, or pulse, it treats sound itself—hiss, hum, feedback, room tone, and the grain of instruments—as the primary material. Performers often use no-input mixing boards, sine-wave samplers, laptops, contact microphones, and extended instrumental techniques to reveal fragile textures and near-silences. Long stretches of space and restraint invite deep listening, making the acoustic qualities of the venue and the audience’s presence integral to the music.

Avant-garde music is an umbrella term for boundary-pushing practices that challenge prevailing norms of harmony, rhythm, timbre, form, and performance. It privileges experimentation, conceptual rigor, and a willingness to reframe what counts as music at all. Historically tied to early 20th‑century artistic modernism, avant-garde music introduced atonality, the emancipation of noise, and new forms of notation and process. It embraces indeterminacy, extended techniques, electronics, spatialization, and multimedia performance, treating sound as material to be sculpted, questioned, and reinvented.
