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.

Jungle is a fast, breakbeat-driven electronic music genre that emerged in the UK in the early 1990s. It is characterized by heavily chopped and re-sequenced funk drum breaks (most famously the Amen, Think, and Apache breaks), deep sub-bass rooted in reggae and dub, and frequent use of ragga and dancehall vocals. Typically around 160–175 BPM, jungle emphasizes syncopation, polyrhythms, ghost-note snare articulations, and swung grooves. Production often features time‑stretching artifacts, pitch‑shifting, rewinds, sirens, and dub‑style effects, creating a kinetic, raw, and rhythmic sound world. While closely related to drum and bass, jungle retains a distinct identity through its reggae/dancehall influence, looser and more chopped breakbeats, rough-and-ready sample aesthetics, and sound system culture sensibility.

Breakcore is a high-intensity electronic music genre built around hyper-edited breakbeats, extreme dynamics, and a deliberately transgressive, collage-like approach to sampling. It prioritizes rhythmic complexity, abrupt structural shifts, and heavy sound design over smooth continuity. Typical tempos range from 160 to 220 BPM (and beyond), with the Amen break, Think break, and other classic breakbeats chopped into micro-fragments, re-sequenced, and processed with distortion, compression, and glitch edits. The palette freely fuses elements from jungle and drum and bass with gabber kicks, industrial noise, classical or choral snippets, ragga vocals, metal guitar samples, and odd-meter patterns. More than a single “sound,” breakcore is a methodology: confrontational energy, maximalist editing, and anti-formalist structures that often subvert dance-music expectations. It thrives in DIY scenes, warehouse parties, and netlabel cultures, where forward-pushing experimentation and boundary-blurring sampling are central values.

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.

Deathstep is an extreme, horror-laden branch of dubstep that fuses the genre’s half‑time lurch and sub‑heavy sound design with the aggression, timbral brutality, and macabre aesthetics of death metal and deathcore. Typically sitting around 140–150 BPM in half‑time, it emphasizes cavernous sub bass, serrated mid‑range growls, blast‑beat‑inspired kick runs, and cinematic, dread‑building intros. Vocals—when present—often borrow from extreme metal (growls, screams) or are sampled from horror cinema to intensify the sense of menace. Compared to brostep, deathstep is darker and more oppressive, prioritizing dissonance, chromatic motion, and percussive violence over anthemics. It thrives in underground labels and SoundCloud circles, with a visual language of decay, sci‑fi horror, and occult imagery.

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.

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.

Extratone is an extreme offshoot of speedcore in which the kick drum is driven so fast (often 600–3,000+ BPM) that successive hits fuse into a continuous tone. Producers shape the kick itself into a pitched oscillator and then "play" melodies and riffs with it. The result is a hyper‑compressed, relentlessly intense wall of sound that blurs rhythm and pitch. Tracks frequently alternate between tonal extratone passages and brief breakdowns, noise bursts, or experimental interludes, emphasizing shock value, sound design virtuosity, and endurance.

Flashcore is an experimental, ultra-fast offshoot of hardcore techno that pushes tempo, sound design, and structural abstraction to extremes. Emerging from the French underground at the end of the 1990s, it rethinks the function of the kick drum and meter, often abandoning dance-floor regularity for fractal, hyper-detailed rhythmic design. Typical tracks range from 250 BPM into the 1000 BPM realm, emphasizing micro-edits, granular textures, spectral processing, and noise-inflected timbres. Rather than building around verse–chorus or steady 4/4 grooves, flashcore pieces are usually through‑composed, textural, and dynamic, borrowing ideas from IDM, noise, and electroacoustic music while retaining the intensity of speedcore and industrial hardcore. The aesthetic is cybernetic and futurist: cold, metallic palettes; atonal or cluster-based harmony; and a focus on tension, disorientation, and controlled chaos. It is both a club-born and art-forward practice, sitting at the intersection of hardcore rave culture and advanced sound art.

Gabber is a Dutch-born branch of hardcore techno characterized by extremely fast tempos, relentless 4/4 kicks, and an aggressive, distorted sound palette. It typically runs between 160–190+ BPM, features heavily overdriven 909-style kick drums that also serve as the bass, terse minor-key synth stabs (including classic "hoover" timbres), and short, shouted vocal samples or MC hype. Culturally, gabber is tied to early-’90s Rotterdam club culture, Thunderdome compilations and events, bomber jackets and trainers, and the high-energy hakken dance. The aesthetic is raw, industrial, and maximal, prioritizing impact, speed, and dancefloor intensity over harmonic complexity.

Gothic (often shortened to goth in a musical context) is a dark, atmospheric strain of post‑punk that emphasizes minor-key harmonies, bass-led grooves, and a brooding, romantic sensibility. It blends the stark urgency of punk with art-rock textural experimentation, icy new-wave synths, and lyrical themes drawn from gothic literature, existentialism, and melancholic introspection. Signature traits include chorus- and reverb-drenched guitars, prominent melodic basslines, steady drum-machine patterns, baritone or ethereal vocals, and a production aesthetic that favors space, echo, and nocturnal ambience. While closely associated with the UK goth subculture, the style quickly spread internationally, influencing parallel scenes such as dark wave, deathrock, and later gothic metal.

Hardcore techno is a high‑tempo, aggressively produced branch of techno characterized by distorted, punchy four‑on‑the‑floor kicks, abrasive sound design, and relentless rhythmic drive. Typical tempos range from about 160 to 190 BPM (and can go even faster in some scenes), creating an intense, physically demanding dance experience. The style emphasizes saturated 909‑style kick drums with clipped/transient "click" and long distorted tails, industrial textures, harsh stabs (including classic "hoover" tones), alarming FX, and short shouted or sampled vocals. Harmony is sparse and often minor, with dissonant intervals or horror/industrial atmospheres. The overall aesthetic is raw, dark, and functional for large rave systems, designed to evoke catharsis and high energy on the dancefloor.

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.

Psycore is an extreme, hyper-fast offshoot of psychedelic trance that emphasizes relentless tempo, dissonant sound design, and wildly intricate rhythmic edits. It typically runs at 170–220+ BPM, pushing beyond darkpsy and hi‑tech into a maximal, chaotic aesthetic. Rather than melodic themes, psycore focuses on texture, timbre, and kinetic motion: FM/PM-sculpted leads, metallic percussions, stuttered bass hits, and constantly mutating effects dominate the mix. The atmosphere is nocturnal, surreal, and often unsettling, designed for deep-night dancefloor intensity and altered-state listening.

Speedcore is an extreme offshoot of hardcore techno and gabber characterized by extremely high tempos, typically 240–350 BPM and often far beyond. Its core is a relentlessly driving 4/4 kick, heavily distorted and clipped into a percussive bass-tone that dominates the spectrum. The style emphasizes aggression and intensity over melody or harmony, drawing on industrial sound design, harsh noise textures, and horror-tinged sampling. Although many tracks are dark and abrasive, some scenes (especially in Japan’s j-core community) blend speedcore tempos with bright, anthemic leads and pop-cultural sampling. Speedcore is both a club style and a studio-centric craft: producers sculpt the kick drum as the central instrument, layering saturation, compression, EQ, and pitch envelopes to achieve the trademark pounding continuum.

Splittercore is an ultra-extreme offshoot of speedcore characterized by blistering tempos—typically 500–1000+ BPM—and relentlessly clipped, staccato kick drums that sound like rapid-fire bursts. The name reflects the signature “split” feeling of ultra-short, overdriven kicks that carve through the mix like shards. Tracks are usually short, brutally loud, and intentionally abrasive, favoring distortion, bitcrushing, and hard clipping over conventional dynamics. Rhythms are programmed at microscopic subdivisions (1/64–1/256 notes and beyond), often with glitchy fills, sudden start–stop edits, and occasional breakcore-style sample splices. Melodic content, when present, tends to be simple rave stabs, shrill leads, or horror/industrial atmospheres, deployed as punctuation between kick barrages. Culturally, splittercore grew from the gabber/speedcore party circuit and DIY netlabel ecosystems, later flourishing online via forums, trackers, and sharing platforms. It sits on the continuum between terrorcore and extratone, pushing speedcore’s velocity to its percussive limit while remaining kick-defined (unlike extratone’s tonal blur).

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.

Hard dance is an umbrella term for a family of high-energy club styles that fuse the drive of techno with the euphoria of trance and the punch of house. Emerging from the UK club circuit in the mid-to-late 1990s, it is characterized by tough 4/4 kicks, bold lead synths, acid lines, and big breakdowns that resolve into emphatic drops. Tempos typically sit around 135–150 BPM, with arrangements built for DJ mixing and peak-time momentum. The name commonly covers UK hard house, hard trance, hard NRG, and adjacent sounds that emphasized harder percussion, rolling basslines, and euphoric hooks while remaining distinctly dancefloor-focused.
