Ambient is a form of electronic and electroacoustic music that prioritizes tone, atmosphere, and texture over conventional song structures and rhythmic drive. It typically features slow-moving harmonies, sustained drones, gentle timbral shifts, and extensive use of space and silence. Rather than drawing attention to itself through hooks or beats, ambient is designed to be as ignorable as it is interesting, rewarding both background listening and focused immersion. Artists often employ synthesizers, samplers, tape loops, field recordings, and subtle acoustic instruments, with reverb and delay creating a sense of place. Substyles range from luminous, consonant soundscapes to darker, more dissonant atmospheres.

Ambient noise wall (ANW) is a microgenre of noise music that blends the monolithic, unchanging "wall" aesthetics of harsh noise wall with the hushed, enveloping qualities of ambient and drone. Instead of abrasive, high-intensity textures, ANW typically presents a subdued, steady-state roar, hush, or rumble that remains largely static over long durations. The focus is on immersion, timbral depth, and the perception of minute internal movements within an ostensibly unvarying sound mass. Dynamics are minimal, rhythm and melody are absent, and pieces often run for extended lengths, encouraging deep listening and spatial awareness. Typical sources include filtered white/pink/brown noise, room tone, tape hiss, HVAC hums, and distant environmental recordings—shaped with narrow EQ bands, gentle saturation, and compression to form a soft yet impenetrable “wall.” Releases often appear on cassette/CDr with minimalist artwork to reinforce the austere, environmental character of the music.

Atmospheric black metal is a branch of black metal that emphasizes immersive, expansive soundscapes and mood as much as raw aggression. It typically blends tremolo‑picked guitars, blast beats, and harsh vocals with sustained synthesizer pads, reverbs, field recordings, and long-form, meditative song structures. The genre often evokes images of nature, wintry or forested environments, and cosmic vastness. Production ranges from lo‑fi, foggy textures to clear but distant mixes that preserve a sense of space. Harmonically, it leans on minor and modal colors, drones, and repeating motifs to create a trance-like intensity rather than riff-showmanship. Where traditional black metal can be claustrophobically fierce, atmospheric black metal opens the sonic frame—slower passages, ambient interludes, and dynamic arcs are common—so that ferocity and serenity coexist within the same piece.

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.

Blackened crust is a hybrid of black metal’s icy tremolo riffing and harsh shrieks with crust punk’s d-beat drive, power-chord urgency, and politically charged ethos. The style favors raw, abrasive production, minor-key and dissonant harmonies, and tempos that lurch between breakneck blast beats and galloping d-beat/skank rhythms. Guitar tones often lean on buzzy fuzz or chainsaw-like distortion (e.g., HM-2-inspired), while vocals range from caustic hardcore bellows to black metal rasps. Lyrically, it typically inherits crust’s anti-authoritarian, anti-fascist, and socially critical perspective, delivered with black metal’s bleak atmosphere.

Blackened death metal fuses the ferocity, low‑tuned heft, and technical riffing of death metal with the icy tremolo lines, blast‑driven urgency, and occult atmosphere of black metal. The result is a dense, aggressive sound marked by relentless speed, layered guitars, and a stark, often ritualistic mood. Vocals typically alternate between cavernous death growls and rasping black‑metal shrieks. Drums emphasize blast beats, double‑kick barrages, and sudden tempo pivots, while guitars move between chromatic death‑metal riffing and long, minor‑key tremolo phrases. Lyrical themes commonly draw on Satanism, occultism, anti‑cosmic or apocalyptic narratives, and blasphemous or esoteric imagery. Production ranges from raw and abrasive to highly polished and symphonic, depending on the artistic intent.

Chiptune (also called chip music or 8-bit music) is a style of electronic music created with, or emulating, the programmable sound generator (PSG) and FM chips found in vintage game consoles and home computers such as the NES/Famicom, Game Boy, Commodore 64 (SID), Amiga, Atari ST, and others. The sound palette is defined by simple waveforms (square/pulse, triangle, saw, noise), rapid arpeggios that imply chords on limited channels, pitch bends, duty-cycle modulation, and crunchy noise percussion. These constraints lend chiptune its bright, percussive, and highly melodic character, often evoking early video-game aesthetics. While originally utilitarian—music for games and computer demos—the approach evolved into a standalone art form. Contemporary chiptune spans pure hardware-authentic tracks and hybrid productions that blend chip timbres with modern synthesis, drums, vocals, and mixing techniques.

Dark ambient is a subgenre of ambient music that emphasizes ominous, brooding atmospheres, sub-bass rumbles, and textural noise over melody and rhythm. It often evokes feelings of isolation, cosmic dread, sanctified ritual, or post-industrial decay, prioritizing mood and immersion above traditional song structure. Typical sound design includes layered drones, heavily processed field recordings, metallic resonances, dissonant tone clusters, and cavernous reverbs. The music tends to evolve slowly over long durations, with subtle timbral shifts and spectral motion substituting for harmonic progression or beat-driven momentum.

Death industrial is a bleak, slow-moving offshoot of post-industrial music that fuses the oppressive electronics of power electronics with the cavernous atmospheres of dark ambient. It favors heavy, corroded textures, throttled dynamics, and a ritualistic sense of pace over conventional song structures. Typical tracks revolve around grim loops of rumbling low-end, metallic drags, and asphyxiating drones, punctuated by sparse, reverberant percussion and eruptions of saturated noise. Vocals—when present—are usually shouted, whispered, or processed into inhuman growls, often conveying themes of death, decay, pathology, and abjection. The production aesthetic embraces tape hiss, feedback, clipping, and analog grime, creating a sense of claustrophobic physicality.

Death metal is an extreme subgenre of heavy metal defined by heavily distorted, low‑tuned guitars, rapid and complex riffing, blast beat drumming, and harsh guttural vocals. Its harmonic language favors chromaticism, dissonance, and tremolo-picked lines that create an ominous, abrasive atmosphere. Lyrically, death metal often explores dark or transgressive themes—mortality, mythology, anti-religion, psychological horror, and the macabre—sometimes with philosophical or social commentary. Production ranges from raw and cavernous to hyper-precise and technical, reflecting the genre’s many regional scenes and substyles. From the mid‑1980s Florida scene (Tampa) and parallel developments in the US, UK, and Sweden, death metal evolved into numerous branches including brutal death metal, technical death metal, melodic death metal, and death‑doom, each emphasizing different aspects of speed, complexity, melody, or heaviness.

Depressive black metal (often abbreviated DSBM) is a bleak, slow- to mid‑tempo branch of black metal that foregrounds introspective melancholy, nihilism, and themes of isolation, self‑destruction, and mental anguish. Musically it blends raw, lo‑fi black metal timbres—tremolo‑picked minor‑key riffs, thin and reverb‑soaked guitars, and frigid drum patterns—with the weight and space of doom metal and the ambience of dark ambient. Vocals are typically anguished, high‑pitched wails, desperate shrieks, or murmured/whispered confessions rather than triumphal grimness. Clean guitar interludes, sparse piano, synth pads, and repetitive hypnotic motifs are common, creating a numbed, dirge‑like atmosphere. Compared with traditional second‑wave black metal, DSBM is less aggressive and more inward‑facing, favoring minimalist, slowly evolving arrangements and mournful melody over speed or technical display.

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 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.

Harsh noise is an extreme form of noise music characterized by dense, high-volume, full-spectrum distortion that largely rejects melody, harmony, and conventional rhythm. It focuses on texture, saturation, and the psychoacoustic impact of sound. Rather than songs, works are often evolving blocks of feedback, amplified object sounds, and overloaded electronics, shaped into walls, bursts, or streams of sonic pressure. The aesthetic foregrounds physical intensity, unpredictability, and timbral complexity, often presented at ear-splitting sound-pressure levels. Although related to industrial and power electronics, harsh noise minimizes the role of beat and voice, emphasizing raw noise generation and continuous timbral sculpting. The scene is deeply DIY, thriving on small-run tapes, CDrs, and underground performance spaces.

Harsh noise wall (often abbreviated HNW) is an extreme substyle of noise that focuses on producing a monolithic, static "wall" of sound with virtually no perceivable change over long durations. The texture is typically broadband, high-gain, and unrelentingly loud, emphasizing sheer density and timbral grain over dynamics, rhythm, or melody. Aesthetically, HNW tends toward minimalism and austerity: the piece begins and, for the most part, remains the same until it ends. This reduction of musical events is intentional, directing the listener’s attention to micro-level fluctuations in the sound mass, bodily perception, and the temporal experience of endurance. Releases are commonly issued in long-form formats and often feature stark visual presentation and conceptual themes of anonymity, erasure, or anti-performance.

Melodic black metal blends the cold, tremolo-picked fury of second‑wave black metal with the twin‑guitar harmonies, lead motifs, and songcraft associated with melodic death metal. It retains rasped vocals, blast beats, and a bleak atmosphere, but favors clearer production, memorable guitar themes, and dramatic minor‑key progressions over lo‑fi abrasion. The result is a sound that is simultaneously aggressive and epic, often evoking wintery landscapes, nihilism, myth, and existential grandeur.

Metal (often used to mean heavy metal in its broad, umbrella sense) is a loud, guitar-driven style of rock defined by high-gain distortion, emphatic and often martial rhythms, and a dense, powerful low end. It foregrounds riff-based songwriting, dramatic dynamics, virtuosic guitar solos, and commanding vocals that range from melodic wails to aggressive snarls and growls. Harmonically, metal favors minor modes, modal color (Aeolian, Phrygian), chromaticism, and tritone-inflected tension, while thematically it explores power, mythology, the occult, social critique, fantasy, and existential subjects. While adjacent to hard rock, metal typically pushes amplification, distortion, precision, and thematic intensity further, forming a foundation for many specialized subgenres.

Noise is an experimental music genre that uses non-traditional sound sources, distortion, feedback, and extreme dynamics as primary musical materials. Instead of emphasizing melody, harmony, or conventional rhythm, it focuses on texture, density, timbre, and the physical presence of sound. Practitioners sculpt saturated walls of sound, piercing feedback, metallic clatter, contact-mic scrapes, tape hiss, and electronic interference into works that can be confrontational or meditative. Performances often highlight process and immediacy—improvisation, body movement, and site-specific acoustics—while recordings can range from lo-fi cassette overload to meticulously layered studio constructions. Though rooted in early avant-garde ideas, the genre coalesced as a distinct practice in the late 1970s and 1980s, especially through Japan’s ‘Japanoise’ scene, and subsequently influenced numerous styles across industrial, punk-adjacent, and experimental electronic music.

Old school death metal (OSDM) is the formative, raw strain of death metal that took shape in the mid-to-late 1980s. It emphasizes downtuned, palm-muted riffing, tremolo-picked lines, and thunderous drums that shift between blast beats, skank beats, and mid-tempo stomps. Vocals are guttural and cavernous, projecting themes of mortality, horror, occultism, and decay. Production is intentionally unvarnished: guitars are thick and abrasive, drums are natural and roomy, and mixes privilege heaviness and atmosphere over precision. US bands typically favored tight, chug-heavy riff chains and chromatic menace, while the Swedish branch popularized the infamous “buzzsaw” guitar tone driven by the Boss HM-2 pedal. Song structures often unfold as riff-suites rather than strict verse–chorus forms, creating an inexorable, subterranean momentum.

Poetry (as a recorded genre) centers on the spoken or performed recitation of verse, foregrounding voice, diction, rhythm, and imagery over conventional song structure. Performances may be entirely unaccompanied or framed by sparse accompaniment such as piano, strings, jazz combos, drones, or subtle sound design. Unlike broader spoken word, which can include storytelling, monologues, and comedy, poetry recordings focus on literary verse—metered, rhymed, or free—delivered with attention to prosody and poetic form. Releases range from archival readings by canonical poets to contemporary performance sets recorded in studios, classrooms, libraries, and clubs. The listening experience often emphasizes intimacy and textual clarity: microphones capture breath, cadence, and silence, while arrangements (if any) remain secondary to the poem’s language and pacing.

Power electronics is an extreme offshoot of industrial and noise music characterized by high-gain feedback, piercing oscillators, abrasive drones, and confrontational, often shouted or screamed vocal performances. The music typically rejects conventional rhythm, melody, and harmony, favoring raw, atonal textures sculpted with distortion, EQ, and dynamics. Lyrical content is deliberately transgressive—fixated on power, control, taboo, and violence—presented either as provocation, critique, or uncomfortable reportage. Performances are frequently intense and minimalist: a few analog synths or tone generators, a mixer pushed into clipping, a microphone, and a handful of pedals can fill the spectrum with searing noise. The aesthetic is stark, ascetic, and confrontational rather than dance-oriented, aligning it more with performance art than club culture.

Symphonic black metal fuses the speed, tremolo-picked riffing, and shrieked vocals of black metal with orchestral writing, choirs, and cinematic arrangements. It expands the genre’s raw ferocity into a grand, theatrical sound that can feel both infernal and majestic. Keyboards or full orchestras handle strings, brass, and choral parts that support or counterpoint the guitars, while blast beats and double‑kick patterns drive the intensity. Harmonically, it leans on minor modes, chromatic motion, and diminished sonorities, often evoking Romantic and late‑Romantic classical drama. Lyrical themes tend toward the occult, mythology, Gothic romance, and horror, and productions range from deliberately grim to highly polished, integrating extreme metal power with film‑score scale.

Ambient folk blends the acoustic intimacy of folk with the spacious sound design of ambient music. Fingerpicked guitars, soft vocals, and organic instruments are layered with drones, reverb-drenched pads, and field recordings to create a hushed, immersive atmosphere. The style favors slow tempos, minimal percussion, and modal or diatonic harmonies, often allowing chords to ring while textures evolve gradually. The result is music that feels pastoral and introspective, equally suited to close listening and quiet, reflective spaces.

Cascadian black metal is a regional strain of atmospheric black metal associated with the Pacific Northwest of North America, named after the Cascadia bioregion. It emphasizes long, immersive song forms; organic, reverb‑washed guitar layers; and a deep engagement with wilderness, seasonality, and eco‑spiritual or animist themes. Musically it blends second‑wave black metal tremolo riffing and blast beats with passages of ambient/drone, post‑rock crescendos, and occasional acoustic or folk interludes. Field recordings of rain, wind, streams, and forest ambience are common, and production tends to favor a raw yet warm, “natural” sound over clinical polish.

Post-black metal is a modern evolution of black metal that blends its tremolo-picked guitars, blast beats, and harsh vocals with the cinematic crescendos and textural depth of post-rock and shoegaze. Often brighter and more melodic than traditional black metal, it favors expansive song structures, reverb-drenched guitar layers, and a mix of screamed and ethereal clean vocals. Harmony tends toward consonant, suspended, and add9/maj7 voicings, creating a bittersweet, nostalgic atmosphere rather than pure abrasion. The style overlaps with, and is sometimes called, blackgaze; however, “post-black metal” is the broader umbrella, encompassing influences from post-rock, indie rock, ambient, and post-metal alongside shoegaze.

USBM (United States Black Metal) is the American branch of black metal, marked by a wide stylistic spectrum that runs from raw, lo‑fi ferocity to expansive, atmospheric and genre‑blurring forms. While it preserves the core elements of black metal—tremolo‑picked guitars, blast beats, and shrieked vocals—it often emphasizes individualism, existential or nature‑focused themes, and an experimental approach that draws from punk, ambient, post‑rock, and noise. Regional currents are notable: the Pacific Northwest (often dubbed “Cascadian”) favors long, immersive songs and environmental/nature themes; other hubs (California, the Midwest, the Northeast, and Texas) contributed raw, depressive, and progressive strains that helped define a distinctly American identity within black metal.

Progressive black metal is a style of black metal that retains the genre’s core extremity—tremolo-picked riffing, harsh vocals, blast beats, and bleak atmospheres—while integrating progressive music traits. It commonly features longer song structures, frequent tempo and meter changes, expanded harmonic vocabulary, and a wider palette of textures (clean guitars, keyboards, jazz-influenced chords, or post-rock dynamics). Compared with orthodox black metal, it often prioritizes compositional development and narrative flow over strict minimalism, while still aiming for a cold, dramatic, or transcendent emotional impact.
