Tone List

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.

Black metal is a form of extreme metal defined by fast tempos, tremolo‑picked guitar lines, blast‑beat drumming, shrieked or rasped vocals, and a deliberately raw, icy production aesthetic. Harmonically, it favors minor and modal collections (especially Aeolian and Phrygian), open-string drones, parallel fifths and fourths, tritones, and sparse or suspended chord voicings over blues-derived harmony. Arrangements often employ layered guitars, long-form song structures, and enveloping reverb to create a bleak, otherworldly atmosphere. The genre’s visual and thematic language is equally distinctive: corpse paint, monochrome artwork, and lyrics exploring anti-dogma, nature, pagan myth, cosmic nihilism, and misanthropy. While some scenes have been associated with controversy and extremism, the musical identity centers on sound, atmosphere, and aesthetics rather than any single ideology.

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.

Minimalism is a style of Western art music that emerged in the United States during the 1960s, characterized by the use of very limited musical materials, steady pulse, and extensive repetition. Composers often build pieces from short cells or motifs that are repeated and slowly transformed through additive or subtractive processes, phase shifting, and gradual changes in harmony, texture, or register. Harmony is typically consonant (often modal or diatonic), though just intonation and extended drones are also common. The result is music that foregrounds process, clarity, audibility of structure, and a hypnotic sense of stasis and flow. Typical ensembles include keyboards, mallet percussion, strings, winds, voices, and electronics or tape. Minimalism influenced a wide array of later styles, from ambient and new age to post-minimalism and minimal techno.

Overtone singing (also called overtone chanting, harmonic or diphonic singing) is a vocal technique in which a single singer produces two clearly perceivable pitches at the same time: a low fundamental drone and a high, flute‑like melody formed from the harmonic series. By precisely shaping the vocal tract (tongue position, lip rounding, soft‑palate height, and jaw opening), the singer selectively amplifies individual overtones above a continuous drone. Regional styles include Tuvan and Mongolian khöömei (with substyles such as sygyt, khöömei, and kargyraa), as well as Tibetan Buddhist and other Inner/Central Asian chant practices. Modern practitioners also employ the technique in ambient, experimental, choral, and meditative music. Timbrally, overtone singing ranges from bright, whistling tones to deep, growling textures. Musically it often centers on drones, pentatonic figures, and melodies that trace the natural harmonic series rather than equal‑tempered scales.

Throat singing is an umbrella term for several vocal practices found across the world in which singers deliberately excite and filter the harmonic (overtone) series above a sustained fundamental, often with a distinctly guttural or pressed tone. The result is the perception of more than one pitch at the same time: a drone-like low note plus a whistling, flute‑like harmonic melody. While best known from Inner Asia (e.g., Tuva and Mongolia), related practices also appear among Inuit communities in the Arctic (katajjaq), the Ainu (rekuhkara), and in parts of Siberia and elsewhere. Techniques and aesthetics vary by region, but common elements include a stable drone, overtone selection using precise shaping of the vocal tract, and close ties to landscape, animal mimicry, and ritual or communal functions.
