Ambient trance is a fusion of trance’s hypnotic pulse with the spacious, atmospheric textures of ambient music. It favors long, evolving arrangements, subdued percussion, and immersive sound design over high-energy drops, creating a transporting, meditative flow. Typical tracks sit on a steady 4/4 grid with gentle, soft‑edged kicks and wide pads, using reverb, delay, and filtering to blur edges and suggest vast space. Melodies are often simple and slowly unfolding, while harmony leans toward modal or consonant progressions that sustain a calm, contemplative mood.

Art pop is a strand of pop music that treats the pop song as a canvas for high-concept ideas, experimental techniques, and cross-media aesthetics. It marries accessible melodies and hooks with the visual culture of art schools, the conceptual rigor of the avant-garde, and the studio-as-instrument ethos. Sonically, art pop favors eclectic instrumentation (synths, orchestral timbres, guitars, found sounds), unusual song forms, and sophisticated harmony. It often employs collage, musique concrète–like textures, and theatrical vocal delivery while still keeping a pop-facing surface. Beyond sound, art pop is deeply visual and conceptual: albums are framed as coherent artworks, stagecraft and video are integral, and lyrics tend toward intertextuality, character work, irony, and social commentary. The result is pop that is both immediate and idea-driven.

Juke is a fast, sample-driven club style from Chicago that runs around 150–160 BPM, built on jagged 808/909 drum programming, booming sub‑bass, and looped vocal chants. It keeps the raw, minimal, party‑starting energy of ghetto house but pushes the tempo and rhythmic syncopation much further. Tracks often rely on short, repetitive hooks and call‑and‑response phrases, claps on the backbeat, and tom/snare rolls that stutter and pivot around a steady 4/4 grid. Harmonic content is sparse—brief chord stabs, simple bass riffs, and plenty of negative space—so that dancers can lock into the drums. Juke is closely related to, and historically precedes, Chicago footwork; where juke is the more club‑aligned, chant‑heavy form, footwork became more abstract and battle‑oriented.

Downtempo is a mellow, groove-oriented branch of electronic music characterized by slower tempos, plush textures, and a focus on atmosphere over dancefloor intensity. Typical tempos range from about 60–110 BPM, with swung or laid-back rhythms, dub-informed basslines, and warm, jazz-tinged harmonies. Stylistically, it blends the spaciousness of ambient, the head-nodding rhythms of hip hop and breakbeat, and the cosmopolitan smoothness of lounge and acid jazz. Producers often use sampled drums, Rhodes or Wurlitzer electric pianos, guitar licks with delay, and field recordings to create intimate, cinematic soundscapes. The mood spans from soulful and romantic to introspective and dusk-lit, making it a staple of after-hours listening, cafes, and relaxed club back rooms.

Dubstep is a bass‑centric electronic dance music genre that emerged in South London in the early 2000s. It is typically around 140 BPM and is defined by a half‑time rhythmic feel, sub‑heavy basslines, sparse yet impactful drums, and a strong emphasis on space, tension, and sound system weight. Hallmark traits include syncopated kick patterns, snares on the third beat of the bar, swung/shuffly hi‑hats inherited from UK garage, and modulated low‑frequency bass (“wobbles”) shaped with LFOs, filters, and distortion. Influences from dub reggae (echo, delay, and minimalism), jungle/drum & bass (bass science and sound system culture), and 2‑step garage (rhythmic swing and shuffles) are central. The style ranges from deep, meditative “dub” aesthetics (often called deep dubstep) to more aggressive, midrange‑driven variants that later informed brostep and festival bass. Atmosphere, negative space, and subwoofer translation are as important as melody or harmony.

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.

Footwork (often called juke or Chicago juke) is a high‑velocity, sample‑driven form of electronic dance music that emerged from Chicago’s battle‑dance culture. Built around stuttering, off‑grid percussion at roughly 160 BPM, it uses chopped vocal snippets, booming sub‑bass, and rapid toms, claps, and snares arranged in highly syncopated patterns that are not locked to a constant 4/4 kick. Producers frequently slice fragments of rap, R&B, pop, and soul into call‑and‑response hooks that interact with dancers on the floor. The result is a tense, kinetic sound designed for competitive circles as much as for clubs and headphones.

Footwork jungle is a hybrid of Chicago footwork’s 160 BPM battle-ready minimalism and the UK’s early-’90s jungle breakbeat science. It marries chopped Amen/Think breaks, sub-heavy 808 bass, and halftime/duple-feel syncopation with footwork-style vocal chops, call‑and‑response samples, and spacious, rave‑born atmospherics. The result is music that can flex between heads‑down listening and high‑intensity dance movement, retaining jungle’s rolling momentum while adopting footwork’s off‑grid micro‑rhythm and negative space.

Future garage is a UK-born mutation of UK garage and dubstep that pivots from peak-time club energy toward intimate, headphone-focused listening. It is defined by shuffling 2‑step drum programming (swung hi‑hats, syncopated snares, ghost kicks), deep sine/sub bass, foggy pads, and the use of pitched, chopped R&B or soul vocal fragments as texture rather than lead melody. Producers often weave in field recordings (rain, street noise, vinyl crackle), generous reverb, and subtle sound-design to evoke a nocturnal, reflective atmosphere. Typical tempos hover around 130 BPM, with grooves that imply both half‑time glide and garage shuffle, and harmony that favors minor keys, suspended chords, and slow-moving, emotive progressions.

House is a dance music genre that emerged in Chicago in the early 1980s, defined by a steady four-on-the-floor kick drum, off-beat hi-hats, soulful or hypnotic vocals, and groove-centric basslines. Typical tempos range from 118–130 BPM, and tracks are structured in DJ-friendly 16–32 bar phrases designed for seamless mixing. Drawing on disco’s celebratory spirit, electro-funk’s drum-machine rigor, and Italo/Hi-NRG’s synth-led sheen, house prioritizes repetition, tension-and-release, and communal energy on the dancefloor. Its sound palette often includes 808/909 drums, sampled or replayed disco/funk elements, filtered loops, piano/organ stabs, and warm, jazzy chords. Over time, house diversified into many substyles—deep house, acid house, French house, tech house, progressive house, and more—yet it remains a global foundation of club culture, known for emphasizing groove, inclusivity, and euphoria.

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.

Microhouse is a sparse, detail‑oriented strain of house music that strips grooves down to their essentials and focuses on micro‑edits, subtle percussive textures, and small timbral changes over time. Typically hovering around 118–126 BPM, it favors dry 4/4 kicks, shuffled hi‑hats, sub‑bass pulses, and meticulously arranged glitches, clicks, and found sounds. Rather than big breakdowns, microhouse builds tension through repetition, negative space, and tiny variations, often borrowing the reductionist ethos of minimal techno and the textural play of glitch and IDM. The result is club music that feels intimate and hypnotic: danceable yet restrained, warm yet abstract, and deeply attentive to sound design and micro‑timing.

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.

Post-dubstep is a loosely defined wave of UK-born electronic music that grew out of dubstep but moved away from its rigid 140 BPM wobble-bass formula. It keeps the bass-weight, sound-system focus, and rhythmic syncopation of dubstep and UK garage, but folds in house and techno tempos, R&B vocal chops, ambient space, and experimental production. Typical tracks explore 120–135 BPM (not fixed at 140), use broken 2‑step/garage swing instead of 4/4, and favor detailed sound design over maximal drops. You’ll often hear hushed, intimate vocals (sampled or original), neo-soul/jazz-influenced chords, and micro-edited percussion with lots of negative space. The mood is frequently introspective, melancholic, and textural—more headphone-oriented than festival-leaning—yet still rooted in club culture.

Progressive electronic is a 1970s-born branch of electronic music that applies the exploratory ethos of progressive rock to synthesizers, sequencers, and studio-as-instrument techniques. It favors long-form structures, evolving textures, and thematic development over verse–chorus song forms. Hallmarks include analog synth timbres (Moog, ARP), step-sequenced ostinatos, spacious tape and plate reverbs, and gradual modulation of filters and envelopes. The music often embraces minimalistic repetition, cosmic and cinematic atmospheres, and a sense of narrative journey, connecting it to krautrock’s experimentalism and early ambient’s focus on tone and space.

Progressive house is a melodic, long-form strain of house music known for gradual builds, evolving textures, and a strong sense of tension and release. It favors hypnotic grooves, lush pads, and emotive chord progressions over abrupt drops. Typically sitting around 122–128 BPM in 4/4 time, tracks unfold over six to nine minutes, introducing small changes every few bars to keep momentum. The sound balances club-focused punch with cinematic atmosphere, making it equally at home in late-night dancefloors and long-form DJ sets.

UK garage is a British evolution of US garage/house that emerged in the mid-to-late 1990s around London’s pirate radio, record shops, and clubs. It is characterized by shuffling, syncopated rhythms, swung hi‑hats, crisp snares, and a pronounced sense of groove at roughly 130–138 BPM. The style blends house’s soulful chords and R&B vocals with jungle/drum & bass sound-system bass weight, often featuring chopped and time‑stretched vocal samples, organ/piano stabs, and warm Rhodes textures. Two major strands formed: 4x4 (straight four-on-the-floor with heavy swing) and 2‑step (broken kick patterns that avoid a constant four-on-the-floor). MC toasting and call‑and‑response vocals became a signature of the scene. Substyles include speed garage (darker, bass‑heavier, often with wobbly LFO bass) and 2‑step (sparser, more syncopated drums). UK garage’s club‑ready energy and vocal sensibility propelled it into the mainstream and laid the groundwork for grime, dubstep, bassline, and UK funky.

UK bass is a broad, club‑focused umbrella for post‑garage and post‑dubstep sounds that prioritise heavy low‑end, syncopated percussion, and experimental sound design. It is less a single rigid rhythm than a producer and DJ culture that centers sub‑bass weight and British club lineage at tempos commonly between 120–140 BPM. Drawing on UK garage, dubstep, grime, bassline, UK funky, house, techno, jungle, and dub, UK bass folds shuffling grooves, half‑time lurch, and broken‑beat swing into forward‑thinking arrangements. Labels and crews such as Hessle Audio and Night Slugs helped codify its aesthetic: tactile subs, punchy drums, sparse but impactful harmony, and club‑system dynamics that reward both dancers and deep listeners.
