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.

Vocal jazz is a jazz tradition in which the human voice is treated as an instrument—matching the phrasing, articulation, and timbral nuance of horns or piano. Singers often improvise melodically and rhythmically, including using scat singing (nonsense syllables) to emulate instrumental solos. At the same time, many vocal‑jazz performances favor traditional, pop‑leaning song structures and clear lyric delivery, reducing the overall role of extended improvisation compared with small‑group instrumental jazz. Repertoires frequently draw from Tin Pan Alley and Broadway standards (the Great American Songbook), rendered with swing, ballad, or Latin feels.

Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.
