Noise à Noise

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.

Classical music is the notated art-music tradition of Europe and its global descendants, characterized by durable forms, carefully codified harmony and counterpoint, and a literate score-based practice. The term “classical” can refer broadly to the entire Western art-music lineage from the Medieval era to today, not just the Classical period (c. 1750s–1820s). It privileges long-form structures (such as symphonies, sonatas, concertos, masses, and operas), functional or modal harmony, thematic development, and timbral nuance across ensembles ranging from solo instruments to full orchestras and choirs. Across centuries, the style evolved from chant and modal polyphony to tonal harmony, and later to post-tonal idioms, while maintaining a shared emphasis on written notation, performance practice, and craft.

Contemporary classical is the broad field of Western art music created after World War II. It embraces an array of aesthetics—from serialism and indeterminacy to minimalism, spectralism, electroacoustic practices, and post‑tonal lyricism—while retaining a concern for notated composition and timbral innovation. Unlike the unified styles of earlier eras, contemporary classical is pluralistic. Composers freely mix acoustic and electronic sound, expand instrumental techniques, adopt non‑Western tuning and rhythm, and explore new forms, from process-based structures to open and graphic scores. The result is a music that can be rigorously complex or radically simple, technologically experimental or intimately acoustic, yet consistently focused on extending how musical time, timbre, and form can be shaped.

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.

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.

Electro is an early 1980s machine-funk style built around drum machines (especially the Roland TR-808), sequenced basslines, and a futuristic, robotic aesthetic. It emphasizes syncopated rhythms, sparse arrangements, and timbres drawn from analog and early digital synthesizers. Vocals, when present, are often delivered via vocoder or rap-style chants, reinforcing a sci‑fi, cyborg persona. Electro’s grooves powered breakdance culture, and its sonic palette—crisp 808 kicks, snappy snares, dry claps, cowbells, and squelchy bass—became foundational to later techno and bass music.

Electroacoustic music is a broad art-music tradition that integrates recorded acoustic sound and electronically generated or processed sound into coherent musical works. It privileges timbre, gesture, texture, and spatialization over conventional melody-and-harmony song forms, often employing tape manipulation, synthesis, live electronics, and computer-based signal processing. Works are frequently composed for fixed media (stereo or multichannel loudspeakers) and may also involve live performers who are transformed in real time. Concert presentation typically emphasizes spatial diffusion and immersive listening, and the repertoire spans concert works, radio pieces, installations, and soundscape compositions.

Electronic is a broad umbrella genre defined by the primary use of electronically generated or electronically processed sound. It encompasses music made with synthesizers, drum machines, samplers, computers, and studio/tape techniques, as well as electroacoustic manipulation of recorded or synthetic sources. The genre ranges from academic and experimental traditions to popular and dance-oriented forms. While its sonic palette is rooted in electricity and circuitry, its aesthetics span minimal and textural explorations, structured song forms, and beat-driven club permutations. Electronic emphasizes sound design, timbre, and studio-as-instrument practices as much as melody and harmony.

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.

Field recording is the practice and genre of capturing sounds in situ—outside the studio—using portable recording equipment. It centers on documenting environments, human activities, wildlife, weather, machinery, rituals, and music as they actually occur, often with minimal intervention. As a listening genre, field recording foregrounds place and presence. Releases may present unprocessed, extended takes (e.g., a shoreline at dawn), or carefully edited sequences that map a soundwalk, a village festival, or a factory floor. The results range from documentary-style fidelity to abstract, immersive soundscapes that emphasize texture, spatiality, and the ecology of sound.

Glitch is an experimental electronic music genre that foregrounds the sounds of technological error—digital clicks, pops, clipping, buffer underruns, CD skipping, software crashes, and bit‑reduction. Rather than hiding artifacts, producers use them as primary musical material, often arranged through extreme micro‑editing and non‑linear sequencing. Texturally, glitch spans austere minimalism to warm, hazy ambience. Rhythms tend to be fragmented and asymmetrical, with sudden cuts, stutters, and silences that create tension and negative space. The palette commonly includes sine‑tone grains, granular clouds, filtered noise, and hyper‑detailed percussive fragments, sometimes sitting over subdued drones or dub‑inflected low end. The style emerged in the late 1990s around labels such as Mille Plateaux, influenced by IDM, minimal techno, and the aesthetics of failure in digital media. It later permeated pop and beat‑driven styles through sound‑design techniques that evoke imperfection and transience.

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.

IDM (often expanded as "Intelligent Dance Music") is a strand of experimental electronic music that applies the sound palette and production methods of club genres to listening-focused, often home-oriented works. It favors intricate rhythm programming, unusual time signatures, and richly textured sound design, blending ambient atmospheres with techno’s pulse, electro’s syncopation, and breakbeat’s fragmentation. The music often de-emphasizes the dancefloor in favor of headphone detail, algorithmic structure, and timbral exploration. The term itself is contentious—many artists rejected the "intelligent" label—yet it became a convenient tag for the early- to mid‑1990s cluster of Warp, Rephlex, and related scenes that foregrounded complexity, abstraction, and emotional ambiguity.

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.

Neofolk is a post-industrial offshoot that blends traditional acoustic folk instrumentation with the austere atmospheres, ritual rhythms, and poetic sensibilities of the industrial and post-punk underground. It often features intimate acoustic guitars, baritone or chant-like vocals, martial or processional percussion, drones, and sparse strings or harmonium. Thematically, neofolk is preoccupied with memory, myth, and modernity—drawing on pagan or pre-Christian motifs, Romantic poetry, war-time remembrance, esoteric philosophy, and nature mysticism. The sound tends to be minimal and deliberate, favoring modal harmony and restrained dynamics that sharpen lyrical focus and mood. While sometimes called “apocalyptic folk,” the label describes the tone rather than a single ideology, as artists span a wide range of personal and political stances.

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.

Non-music is an umbrella category for recorded audio whose primary purpose is not musical performance. It encompasses spoken word, speeches, interviews, poetry readings, comedy, audio documentaries, instructional recordings, field recordings, sound effects, and other forms of organized sound meant to inform, narrate, document, or entertain without relying on melody or conventional song structure. Rather than emphasizing harmony, rhythm, and instrumentation, non-music foregrounds voice, text, ambient sound, narrative flow, informational content, and sonic texture. Its aesthetics range from raw, unedited actuality to highly produced studio works, and its scope spans archival preservation, education, performance art, and mass entertainment.

Opera is a large-scale theatrical genre that combines music, drama, and visual spectacle, in which the story is primarily conveyed through singing accompanied by an orchestra. It unites solo voices, ensembles, and chorus with staging, costumes, and often dance to create a total artwork. Emerging in late Renaissance Italy and flourishing in the Baroque era, opera developed signature forms such as recitative (speech-like singing that advances the plot) and aria (lyrical numbers that explore character and emotion). Over the centuries it evolved diverse national styles—Italian bel canto, French grand opéra, German music drama—while continually experimenting with orchestration, harmony, narrative structure, and stagecraft.

Persian classical (musiqi-e asil) is the art-music tradition of Iran centered on the modal system called dastgāh and its body of canonical melodies known as the radif. Performances are typically intimate and improvisation-forward, unfolding through a succession of gusheh (short melodic pieces) within a dastgāh, guided by recognizable cadential gestures (forud) and a central tone (shāhed). Its sound world features nuanced microtonal inflections using koron (lowered) and sori (raised) accidentals, fluid rhythmic freedom in avāz (non-metric improvisation), and contrasting metered forms like pishdarāmad, chahārmezrāb, tasnif (song), and reng (dance). Core instruments include tar, setar, kamancheh, santur, ney, and tombak (tonbak), with the human voice employing elaborate ornaments (tahrir). The repertoire draws on classical Persian poetry (Hafez, Rumi, Saadi), creating a contemplative, mystical, and deeply expressive aesthetic.

Sound collage is a practice and genre that assembles disparate recorded sounds—speech, field recordings, musical fragments, noise, and media detritus—into a new, cohesive work. It treats recorded sound as raw material to be cut, layered, looped, juxtaposed, and transformed, often privileging texture, timbre, and context over conventional melody and harmony. Emerging from mid‑century tape and electroacoustic experiments, sound collage spans avant‑garde, popular, and club contexts, ranging from radical tape splices to sample‑dense pop and hip‑hop. Because it recontextualizes existing audio, it can be narrative, political, archival, or purely abstract—oscillating between documentary and dreamlike mosaic.

Speech is a non-music recording category focused on intelligible spoken language rather than melody, harmony, or meter. It encompasses political addresses, public announcements, news bulletins, commemorations, and other forms of formal oratory captured as audio. Unlike spoken word poetry or stand-up comedy, the emphasis in speech recordings is on clear rhetoric, message delivery, and documentary value. The production prioritizes intelligibility, natural prosody, and sonic transparency, often avoiding musical accompaniment so that content remains archival, reference-grade, and contextually faithful. From wax cylinders and shellac discs to radio tape, cassettes, digital broadcast, and streaming archives, speech has been a core use-case of audio media, preserving moments of civic life, cultural change, and history in their original voices.

Spoken word is a performance-centered genre where text—poems, monologues, stories, or manifestos—is delivered aloud with musicality in voice rather than through singing. It may be entirely a cappella or accompanied by sparse instrumentation (often jazz combos, ambient textures, or minimal electronics) that frames the cadence and rhetoric of the performer. The emphasis is on language: prosody, pacing, imagery, and argument. Pieces often explore personal narratives, social critique, and political themes, drawing on techniques such as internal rhyme, alliteration, and repetition. While recordings exist, the tradition is fundamentally live, prioritizing immediacy, audience engagement, and oratorical presence.

Terrorcore is an extreme offshoot of hardcore techno that emphasizes very high tempos, heavily distorted kick drums, and horror-themed aesthetics. Tracks typically run from roughly 190–230 BPM or faster, using clipped, overdriven 909-style kicks and harsh percussion to create a relentless, punishing sound. The genre draws on macabre imagery and sound design: eerie pads, atonal stabs, dissonant intervals, and samples from horror films, slashers, and news reports. Vocals—if present—are usually shouted, pitched-down, or sampled, serving texture more than narrative. Arrangement tends to be functional for dancefloors, with short breakdowns and abrupt, explosive drops that prioritize intensity over melodic development.

Modern classical is a contemporary strand of instrumental music that applies classical composition techniques to intimate, cinematic settings. It typically foregrounds piano and strings, is sparsely orchestrated, and embraces ambience, repetition, and timbral detail. Rather than the academic modernism of the early 20th century, modern classical as used today refers to accessible, mood-driven works that sit between classical, ambient, and film music. Felt pianos, close‑miked string quartets, tape hiss, drones, soft electronics, and minimal harmonic movement are common, producing a contemplative, emotionally direct sound that translates well to headphones, streaming playlists, and screen media.
