American gamelan is a movement within contemporary classical and experimental music in the United States that creates new repertoire for gamelan-style ensembles built or adapted outside Indonesia. It draws on the cyclical, layered textures of Javanese and Balinese gamelan while embracing American instrument-building, just-intonation tunings, and minimalist process techniques. Ensembles often use homemade metallophones, gongs, and resonators fabricated from aluminum, steel, and other materials, producing a shimmering, bell-like sonority that is at once Indonesian-inspired and distinctively American. Unlike traditional Indonesian genres tied to court, ritual, or theatre, American gamelan typically serves the concert stage and educational settings, favoring newly composed works, cross-cultural collaborations, and experiments that combine gamelan with Western instruments, voice, or electronics.

Experimental music is an umbrella term for practices that prioritize exploration, process, and discovery over adherence to established genre norms. It embraces new sound sources, nonstandard tuning systems, indeterminacy and chance operations, graphic and open-form scores, extended techniques, and technology-led sound design (tape, electronics, computers, and live processing). Rather than a single style, it is a methodology and ethos: testing hypotheses about sound, structure, and performance, often blurring boundaries between composition, improvisation, sound art, and performance art. Listeners can expect unfamiliar timbres, unusual forms, and an emphasis on how music is made as much as the resulting sound.
