Drone is a minimalist music genre defined by sustained tones, long durations, and extremely gradual change. Harmony is often static or centered on a single fundamental with subtle overtone shifts, while rhythm tends toward stasis or very slow pulses. Sound sources range from acoustic instruments (e.g., strings, organ, bagpipes, shruti box, tambura) to electronics (sine waves, oscillators, feedback, tape loops, and later digital synthesis and processing). Many composers favor just intonation or other alternative tuning systems to emphasize beating patterns, psychoacoustic effects, and the internal life of sound. Although drone as a sonic principle is ancient and global, the modern experimental genre cohered in the 1960s through the New York minimalists and related avant‑garde circles, then spread into ambient, experimental, and heavy music scenes. The focus is less on melody and more on timbre, resonance, and the phenomenology of listening.

Experimental vocal is a boundary‑pushing approach to voice that treats the human vocal tract as a full-spectrum instrument. It privileges timbre, texture, and technique over conventional melody and lyric, foregrounding breath, phonemes, and raw sound just as much as sung notes. Artists employ extended vocal techniques such as overtone singing, multiphonics, shrieks, growls, glottal stops, ululation, whistle register, inhaled phonation, tongue clicks, and non-lexical glossolalia. These are often combined with live electronics, tape and granular processing, looping, and spatialization to expand the voice beyond its natural limits. While it overlaps with avant‑garde classical, sound art, and performance art, experimental vocal is not bound to any single tradition. It can be stark and ritualistic, viscerally intense, or meditative and textural, ranging from solo explorations to choral sound masses and multimedia works.
