Acid techno is a harder, more driving offshoot of acid house that blends the squelching lines of the Roland TB-303 with the pounding rhythms and industrial edge of 1990s techno. It favors relentless 4/4 kicks, hypnotic 16th‑note bass patterns with accent and slide, and aggressive resonance sweeps that create a distinctive, corrosive timbre. Emerging largely from the UK free-party and squat-rave scenes, acid techno emphasizes raw energy, immediacy, and live hardware performance. Compared with acid house, it is faster, tougher, and more percussive; compared with mainstream techno, it leans heavily on the 303 as the central hook and motif. Typical tempos range from about 135 to 150 BPM, with arrangements built for long, tension-and-release transitions, filter rides, and layered drum machine grooves tailored to large, physically immersive sound systems.

Ambient house blends the spacious textures and meditative pacing of ambient music with the gentle propulsion of house. It typically features a soft four-on-the-floor kick, airy pads, dub-style effects, and environmental samples that create an immersive, blissed-out soundscape. Tempos are often moderate (roughly 100–120 BPM), with subdued percussion, warm sub-bass, and sparse melodic motifs that prioritize atmosphere over dance-floor intensity. The result is a style suited both to late-night listening and to the "chill-out rooms" that historically complemented more energetic club spaces.

Ambient techno blends the spacious, atmospheric qualities of ambient music with the pulse and structure of techno. It favors subtle four-on-the-floor rhythms, soft-edged percussion, and long-evolving pads and drones over aggressive beats or hooks. Tracks typically unfold slowly across extended lengths, privileging texture, timbre, and psychoacoustic space. The bass is warm and rounded, delays and reverbs are dubby, and harmonic movement is minimal or modal, creating a hypnotic, contemplative flow suited to both attentive listening and late-night dancefloors. Compared with ambient house, ambient techno tends to be more austere and less pop-sample oriented; compared with dub techno, it is often less explicitly rooted in reggae-derived rhythms and may embrace more beatless passages.

Bleep techno (often called "bleep & bass") is a sparse, bass‑heavy strain of early UK techno that emerged in northern England at the turn of the 1990s. It is defined by ultra‑deep sub‑bass inspired by dub reggae sound systems, clean and punchy 808/909 drum programming, and distinctive short "bleep" motifs made from simple waveforms (sine or square). Tempos typically sit around 120–125 BPM, with plenty of negative space, precise quantization, and minimal harmonic content. The style fuses Detroit techno’s futurism with British soundsystem culture, yielding a cool, minimal, machine‑funk aesthetic designed to move large rooms with physical low‑end rather than dense arrangements.

Breakbeat is an electronic dance music style built around syncopated, sampled drum "breaks" rather than a straight four-on-the-floor kick. Producers chop, loop, and rearrange classic drum breaks (such as the Amen, Apache, and Think breaks) to create swung, shuffling rhythms with strong backbeat accents. Emerging from the UK rave continuum, breakbeat draws heavily on hip hop’s sampling culture and electro’s machine-funk, while adopting house/acid-house sound design and club-focused arrangements. Tempos most commonly sit between 125–140 BPM (though broader ranges occur), featuring heavy sub-bass, crunchy snares, and edits/fills that propel dancefloors without relying on a 4/4 kick. As a scene, "breaks" spans everything from big-room, party-leaning grooves to techy, nu skool textures and regional variants like Florida breaks. It also functions as a foundational rhythmic vocabulary that informed jungle and drum and bass, and it underpins much of modern bass music.

Chopped and screwed is a hip-hop remix technique and regional style that slows songs down dramatically—often to around 60–70 BPM—and lowers the pitch, creating a syrupy, heavy-lidded feel. DJs then "chop" the audio by cutting, repeating, and stuttering phrases, adding backspins, brakes, and pauses to exaggerate groove and space. Pioneered in Houston, Texas by DJ Screw in the early 1990s, the sound is closely tied to car culture (SLABs) and the codeine-lean aesthetic. While originally rooted in mixtapes of Southern rap, the approach has since been applied to R&B, pop, and even electronic music, becoming a widely imitated post-production sensibility across the internet era.

Deep house is a subgenre of house music characterized by warm, soulful textures, jazz-influenced harmony, and understated, hypnotic grooves. It typically runs around 115–124 BPM, favoring subtle swing, syncopated percussion, and rounded, mellow basslines over aggressive peaks. Sonically, deep house draws on extended chords (7ths, 9ths, 11ths), Rhodes and M1 organ timbres, airy pads, and tasteful use of reverb and delay to create a spacious, emotive atmosphere. Vocals, when present, often reference soul and gospel traditions, delivering intimate, reflective themes rather than big-room hooks. The style emerged in the mid-to-late 1980s as producers fused Chicago house rhythms with jazz-funk, soul, and garage house sensibilities, resulting in a smoother, deeper take on the house blueprint.

Drill is a subgenre of hip hop that emerged on Chicago’s South Side in the early 2010s. It is defined by stark, menacing production; booming 808 sub‑bass with frequent pitch slides; skittering hi‑hats; and sparse, minor‑key melodies built from pianos, synth pads, strings, bells, or eerie soundscapes. Vocals are typically deadpan or urgent, with ad‑libs punctuating lines. Lyrically, drill foregrounds raw street reportage—survival, trauma, crews, and contested territory—often delivered with bleak realism. Tempos in original Chicago drill tend to sit around 60–75 BPM (often felt in double‑time), while later UK and New York scenes adopt 130–145 BPM grids with off‑kilter snare placement and distinctive sliding 808 patterns. The overall aesthetic prioritizes weighty low end, rhythmic tension, and an uncompromising mood.

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.

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.

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.

Glitch pop is a strain of pop music that foregrounds digital errors and micro-edits as expressive hooks, fusing the tuneful structures of mainstream pop with the textural play of experimental electronica. Producers chop, stutter, and time-stretch vocals; sprinkle in clicks, cuts, and buffer-skip artifacts; and use bit-crushing or granular resynthesis alongside bright synths and catchy choruses. Despite its love of sonic fragmentation, the genre remains song-first: verses and choruses are clearly defined, melodies are memorable, and harmonies tend to be consonant. The friction between pristine songwriting and intentionally broken sound design creates a delicate, intimate, and often melancholic shimmer that feels both futuristic and warmly human.

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.

J-core is a Japanese take on hardcore techno that fuses high-BPM club structures with otaku culture, game/anime sampling, and brightly melodic writing. It typically sits in the 160–200+ BPM range, using pounding four-on-the-floor kicks, gabber-style distorted low-end, or layered breakbeats. The style is defined by hyper-melodic leads (often supersaws), euphoric trance harmonies, and chopped/processed voice clips from anime, games, denpa songs, or Vocaloid. Aesthetically it leans kawaii/cute but can swing toward intense, chaotic, or even speedcore extremes. J-core flourished in Japan’s doujin scene and rhythm-game ecosystem, with circles and labels releasing compilations and event-driven tracks.

Lo-fi is a music aesthetic and genre defined by an embrace of audible imperfections—tape hiss, clipping, room noise, distorted transients, and uneven performance—that would be treated as errors in high-fidelity recording. Emerging from the DIY ethos of American indie and punk scenes, lo-fi turns budget constraints and home-recording limitations into a signature sound. Songs are often intimate, direct, and unvarnished, prioritizing immediacy and personality over polish. Typical lo-fi recordings use 4-track cassette or similarly modest setups, simple chord progressions, and understated vocals, spanning rock, folk, pop, and experimental approaches while retaining a homemade warmth and nostalgic patina.

Midwest emo is a regionally rooted branch of emo that emerged in the American Midwest during the 1990s. It is distinguished by clean, interlocking "twinkly" guitar lines, melodic bass counterpoint, and dynamic, often understated drumming. The style blends the confessional lyricism and DIY ethos of emo with the delicacy and clarity of indie rock, plus the rhythmic and harmonic playfulness of math rock. Vocals tend to be intimate and conversational, while arrangements favor open guitar voicings (add9/sus2), arpeggios, and intricate two‑guitar interplay over high‑gain distortion. While associated with college towns and basement shows, Midwest emo’s influence has spread widely, shaping subsequent waves of emo and inspiring cross‑genre borrowing from indie rock to emo rap.

Minimal synth is a sparse, DIY strand of early electronic music built around a small palette of analog synthesizers, drum machines, and austere melodies. It favors economy: short, hook-like motifs; rigid, metronomic rhythms; and cool, detached vocals that sit in stark relief against the electronics. The sound is defined by dry drum machine patterns (often 2–4 bar loops), monophonic basslines, simple minor-key harmonies, and limited effects—typically delay and reverb used tastefully rather than lavishly. Emerging from post-punk and new wave’s experimental fringes, it captured a mood that was simultaneously intimate and mechanical, melancholic yet danceable. Originally circulated on cassettes and 7" singles via small independent labels, minimal synth has since become a collectors’ and archivists’ favorite, with a 2000s revival highlighting how its disciplined restraint and analog textures anticipated later retro-synth and underground electronic movements.

Minimal techno is a stripped-down, precision-focused branch of techno that emphasizes space, repetition, and subtle change over time. It typically uses a small palette of elements—kick, hi-hats, sparse percussion, a bass pulse, and a few tonal stabs or textures—and relies on micro-variations, dynamics, and timbral modulation to create movement. Rather than dense layering, minimal techno foregrounds negative space and groove, often highlighting the interplay between a hypnotic 4/4 kick and minimal percussive details. The result is a deep, immersive club sound where patience, restraint, and nuance are central to the aesthetic.

Nightcore is an internet-born editing style that speeds up and pitch‑raises existing songs—typically by around a third in speed—so the vocals become brighter and more youthful and the groove turns more urgent. Practically, a classic nightcore edit accelerates a pop, Eurodance, or trance source by roughly 20–35% (the canonical meme is ~35%), which also lifts the pitch by about five and a half semitones—similar to playing a 33⅓‑rpm record at 45 rpm. The result is euphoric, hook‑forward, and highly kinetic, and it is often presented with anime or fan‑art visuals that emphasize its internet‑native identity.

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.

Outsider house is a strain of house music that embraces lo‑fi production, raw textures, and a DIY ethos. Instead of the sleek, club‑polished sound of mainstream house, it foregrounds tape hiss, distortion, and gritty machine funk to create a hazy, intimate atmosphere. Often associated with early‑2010s labels and scenes that prized hardware jams and cassette aesthetics, outsider house sits at the fringes of house and techno while retaining steady 4/4 rhythms for dancefloor use. Tracks tend to be hypnotic and repetitive, with detuned pads, muffled drums, and understated basslines that feel both nostalgic and nocturnal.

Plunderphonics is a sample-based music practice in which new compositions are made entirely or predominantly from pre‑existing recordings. Rather than using short, unrecognizable snippets as texture, plunderphonic works foreground recognizable materials—pop hits, classical excerpts, commercials, voice-overs—and transform them through juxtaposition, layering, pitch-shifting, time-stretching, and collage. Coined by Canadian composer John Oswald in the mid‑1980s, the term names both a technique and a critical stance that questions authorship, originality, and ownership in the age of reproducible media. Plunderphonics often functions as cultural commentary or satire, drawing attention to how meaning changes when familiar sounds are recontextualized. Stylistically, it ranges from dense cut‑up cacophony to groove-oriented rearrangements that remain danceable and accessible.

Pop punk blends the speed and attitude of punk rock with the melody, hooks, and songcraft of pop. It features bright, concise songs driven by crunchy power-chord guitars, punchy drums, and catchy vocal lines that often favor gang shouts and harmonies. Lyrically, pop punk tends to focus on adolescence, relationships, boredom, suburbia, and self-deprecating humor, delivered with a mix of earnestness and wit. Production ranges from raw and DIY to radio-ready polish, but the core is always immediacy: big choruses, tight structures, and energetic performances.

Speed garage is a fast, bass-heavy strain of UK garage that emerged in the late 1990s. It is defined by a driving 4/4 kick, a distinctly swung/shuffled groove, and massive sub‑bass lines that borrow weight, timbre, and attitude from jungle and drum and bass. Typical tracks sit around 132–138 BPM, feature chopped and timestretched R&B or diva vocal snippets, organ house stabs, filter sweeps, and rude‑boy/dancehall samples. Compared with other UK garage styles, speed garage is tougher and more direct: straight four-on-the-floor drums, aggressive bass riffs, and sound system energy designed for big club rigs and rewind culture.
