Abstract hip hop is a deliberately experimental, left-field branch of hip hop that emphasizes mood, texture, and unconventional structures over radio-oriented hooks. Beats are often off-kilter, skeletal, or rhythmically unstable, with heavy use of negative space, collage-like sampling, noise, and ambient wash. Production draws from IDM, illbient, trip hop, and dub, favoring granular edits, tape hiss, vinyl crackle, and detuned or atonal timbres. Vocals, when present, lean toward stream‑of‑consciousness poetics, surreal imagery, dense internal rhyme, and non-linear narrative, frequently eschewing traditional verse–chorus formats. The result is a challenging but evocative sound world—introspective, cinematic, and sometimes abrasive—that reshaped the possibilities of underground hip hop in the late 1990s and 2000s.

Acid jazz is a groove-focused fusion that blends the rhythmic drive of 1970s funk and soul with jazz harmony, improvisation, and DJ culture. Emerging from the UK club scene in the late 1980s, it revived crate-dug "rare groove" aesthetics and reintroduced live instrumentation—Hammond organ, Rhodes, horns, and tight rhythm sections—into contemporary dance music. Stylistically, acid jazz favors mid-tempo, syncopated rhythms, vamp-based structures, extended chords, and concise solos, often paired with warm, analog-leaning production. It sits between dancefloor energy and lounge sophistication, bridging DJs, bands, and studio producers while maintaining a polished, urban, and feel-good mood.

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.

ASMR (Autonomous Sensory Meridian Response) as a music/audio genre focuses on close‑miked, low‑intensity sounds designed to induce relaxation, tingling sensations, and sleep. It typically features whispered speech, soft tapping, brushing, fabric rustling, paper crinkles, page turning, and gentle environmental ambiences arranged with extreme intimacy and spatial detail. Production emphasizes very low noise floors, high gain, slow pacing, and extensive stereo or binaural imaging so that sounds feel physically "near" the listener. Unlike song‑based genres, ASMR is usually non‑metrical, largely aperiodic, and minimally harmonic, prioritizing texture, dynamics, and psychoacoustic immersion over melody and rhythm.

Bedroom pop is an internet-native, DIY strain of pop and indie music characterized by intimate vocals, gentle melodies, and home-recorded production. Artists typically write, record, and mix their songs in domestic spaces using affordable software and minimal gear. Sonically, it blends indie pop and dream pop with lo-fi textures, soft rock chords, and understated electronic beats. The focus is on a confessional, diaristic tone—often whispery or close-mic’d—paired with warm saturation, tape hiss, and nostalgic timbres. Distribution thrives on platforms like YouTube, SoundCloud, and Bandcamp, where self-released tracks can spread virally.

Boogie (often called boogie-funk or post-disco) is a mid‑tempo, synth-forward strain of R&B that emerged as disco’s luminous sheen gave way to sleeker, funkier production. It centers on rubbery basslines (often synth-bass), crisp handclaps and clattering drum-machine patterns, jazzy/modern-soul chord voicings, and hook-laden vocals that celebrate nightlife, romance, and empowerment. Typically sitting around 100–115 BPM, boogie blends the rhythmic insistence of funk with disco’s dancefloor sensibility, replacing full orchestras with analog synths, electric pianos, and early drum machines for a glossy yet warm sound.

Boom bap is a foundational East Coast hip hop style defined by hard, punchy drums—“boom” for the kick and “bap” for the snare—laid under sample-based loops from jazz, soul, and funk records. It typically runs around 85–96 BPM, favors gritty, minimally processed textures (often associated with SP‑1200 and early Akai MPC samplers), and foregrounds lyrical skill: multisyllabic rhyme schemes, internal rhymes, storytelling, street reportage, and battle bars. DJ techniques such as scratching and cut‑choruses are common, and arrangements emphasize head‑nod grooves, sparse basslines, and tight bar structures that give MCs room to “sit in the pocket.”

Chillout is a broad, downtempo-oriented style of electronic music designed for relaxation, decompression, and after-hours listening. It emphasizes spacious atmospheres, gentle grooves, and warm timbres over intensity or virtuosity. Emerging from the “chill-out rooms” of UK and Ibiza clubs, the sound blends ambient pads, soft 4/4 or broken-beat rhythms, and melodic fragments drawn from lounge, jazz, bossa nova, and Balearic traditions. Typical tempos range from about 70–110 BPM, with extended chords, subtle basslines, and abundant reverb and delay to create a sense of depth and calm. Though often used as an umbrella for related styles (ambient, downtempo, trip hop, lounge), chillout retains a distinct focus on mood: it privileges texture, space, and gentle momentum, making it a staple for late-night sets, beach bars, and home listening alike.

Chillwave is a late-2000s microgenre of electronic pop characterized by hazy, retro-tinged synthesizers, lo‑fi textures, understated drum machines, and heavily processed, dreamlike vocals. Its sound evokes sun-faded nostalgia, often referencing 1980s synth-pop and soft rock atmospheres filtered through cassette hiss, chorus, and reverb. Built by bedroom producers during the blog era, chillwave prizes mood over virtuosity: gentle major-seventh harmonies, loop-friendly motifs, and sidechain‑pumped pads create a warm, gauzy drift. Visual and conceptual aesthetics—VHS artifacts, pastel palettes, palm trees, and memories of an endless summer—are integral to its identity.

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.

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.

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.

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.

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.

Electronica is a broad, largely 1990s umbrella term for a spectrum of electronic music crafted as much for immersive, album‑oriented listening as for clubs and raves. It gathers elements from techno, house, ambient, breakbeat, IDM, and hip hop production, emphasizing synthesizers, drum machines, samplers, and studio experimentation. The sound can range from downtempo and atmospheric to hard‑hitting and breakbeat‑driven, but it typically foregrounds sound design, texture, and mood over strict dance‑floor utility. In the mid‑to‑late 1990s the term was used by labels and press—especially in the United States—to market and introduce diverse electronic acts to mainstream rock and pop audiences.

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.

Experimental electronic is an umbrella term for electronic music that foregrounds exploration and innovation over convention. It treats the studio, computer, and synthesizer as laboratories, using techniques such as tape manipulation, modular and software synthesis, feedback systems, granular and spectral processing, algorithmic/generative composition, circuit-bending, and field recording. Rather than regular song forms or dancefloor functionality, it prioritizes timbre, texture, space, and process. Structures may be nonlinear or open-form; harmony is often non-functional or drone-based; rhythm can be free, irregular, or machine-deconstructed. The style overlaps with electroacoustic music, sound art, industrial, ambient, and noise while continually interfacing with club culture and contemporary art contexts.

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.

Folk is a song-centered acoustic tradition rooted in community storytelling, everyday life, and social history. It emphasizes clear melodies, simple harmonies, and lyrics that foreground narrative, protest, and personal testimony. As a modern recorded genre, folk coalesced in the early-to-mid 20th century in the United States out of older ballad, work song, and rural dance traditions. It typically features acoustic instruments (guitar, banjo, fiddle, mandolin, harmonica), strophic song forms, and participatory singing (choruses, call-and-response).

Folktronica blends traditional folk instrumentation and songcraft with electronic production techniques. Acoustic guitars, fiddles, banjos, and hand percussion coexist with samplers, drum machines, granular synthesis, and digital processing. The style often favors intimate, pastoral moods, gently syncopated beats, and textural sound design built from field recordings and tape hiss. It draws on the melodic simplicity and modal flavors of folk while adopting the rhythmic subtlety and timbral experimentation of downtempo, IDM, and ambient music.

Freak folk is a 2000s revival and mutation of psychedelic and traditional folk that embraces eccentric vocals, surreal lyrics, and homespun, experimental arrangements. It blends fingerpicked acoustics and hand percussion with harps, harmoniums, toy instruments, and found sounds, often recorded in lo‑fi, intimate settings. Aesthetically, it is earthy yet otherworldly: pastoral melodies, drones, and modal harmonies coexist with whimsical, childlike timbres and mystical imagery. The scene is closely associated with the New Weird America movement, valuing communal creativity, DIY production, and a porous boundary between folk tradition and avant‑garde exploration.

French house, often called the "French touch," is a sample-centric substyle of house music known for filtering and looping fragments of 1970s–1980s disco, boogie, and funk. It features a steady four-on-the-floor kick, syncopated and swung hi-hats, punchy sampled basslines, and a distinctive "pumping" feel created by heavy sidechain compression. Production commonly emphasizes warm, saturated textures and filter sweeps—automated low‑pass and high‑pass filters that open and close across loops—to create tension and release on the dancefloor. Vocoder or talkbox-tinted vocals, brief earworm hooks, and concise, groove-first arrangements are typical, with tempos usually between 120–128 BPM. The sound is closely associated with Parisian labels and crews from the mid-to-late 1990s and early 2000s, and it helped re-popularize disco aesthetics within contemporary dance music.

Funk is a rhythm-forward African American popular music style that centers on groove, syncopation, and interlocking parts. Rather than emphasizing complex chord progressions, funk builds tight, repetitive vamps that highlight the rhythm section and create an irresistible dance feel. The genre is marked by syncopated drum patterns, melodic yet percussive bass lines, choppy guitar "chanks," punchy horn stabs, call‑and‑response vocals, and a strong backbeat. Funk’s stripped-down harmony, prominent use of the one (accenting the downbeat), and polyrhythmic layering draw deeply from soul, rhythm and blues, jazz, gospel, and African rhythmic traditions. From James Brown’s late-1960s innovations through the expansive P-Funk universe and the slicker sounds of the 1970s and 1980s, funk has continually evolved while seeding countless other genres, from disco and hip hop to house and modern R&B.

Future funk is an internet-born dance microgenre that fuses the sample-heavy ethos of vaporwave with the upbeat grooves of disco, funk, and Japanese city pop. Producers typically chop and pitch up catchy hooks from late-1970s and 1980s records, loop them over four-on-the-floor drums, and apply filter sweeps and sidechain compression in the spirit of French house. The result is a sparkling, high-energy sound that feels both retro and forward-looking. Visually and culturally, the scene leans into neon-soaked, anime-tinged aesthetics and nostalgic party energy, turning classic pop and boogie flavors into compact, danceable edits tailored for the web era.

Hard bop is a mid-1950s evolution of bebop that grounds modern jazz in the earthy sounds of blues, gospel, and rhythm and blues. It keeps bebop’s small-group virtuosity and improvisational focus, but favors punchy, riff-based themes, singable melodies, and a stronger, groove-forward swing. Typically performed by quintets or sextets (trumpet, tenor sax, piano, bass, and drums), hard bop emphasizes driving ride-cymbal swing, walking bass, and piano comping with bluesy voicings and percussive “block-chord” figures. Its compositions often use 12-bar blues, rhythm changes, and 32-bar AABA song forms, and may feature call-and-response horn writing and shout-chorus style interludes. The style is closely associated with the East Coast and the Blue Note/Prestige sound: tight arrangements, soulful heads, and extended, expressive solos.

Hip hop is a cultural and musical movement that emerged from Black, Latino, and Caribbean communities, centering around rapping (MCing), DJing/turntablism, sampling-based production, and rhythmic speech over beats. It prioritizes groove, wordplay, and storytelling, often reflecting the social realities of urban life. Musically, hip hop is built on drum-centric rhythms (from breakbeats to 808 patterns), looped samples, and bass-forward mixes. Lyrically, it ranges from party anthems and braggadocio to political commentary and intricate poetic forms, with flow, cadence, and rhyme density as core expressive tools. Beyond music, hip hop encompasses a broader culture, historically intertwined with graffiti, b-boying/b-girling (breakdance), fashion, and street entrepreneurship, making it both an art form and a global social language.

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.

Indie pop is a melodic, DIY-rooted branch of alternative music that blends the immediacy of pop songwriting with the independence and aesthetics of underground scenes. It typically features jangly, clean-toned guitars, tuneful bass lines, compact song structures, and intimate, literate lyrics that balance sweetness with subtle melancholy. The sound often leans toward bright chord progressions, earworm choruses, and understated production, favoring charm and personality over gloss. Culturally, indie pop is tied to small labels, fanzines, and community radio, with influential scenes and imprints such as Postcard, Sarah, and Creation laying the groundwork for its global diffusion.

Indie rock is a guitar-centered rock music movement defined as much by its independent production and DIY ethos as by specific sonic traits. Early practitioners worked outside major-label systems, distributing music via small labels, college radio, and fanzines, which fostered a culture of experimentation and community. Sonically, indie rock ranges from jangly, melodic songs to abrasive noise-leaning textures, from lo-fi home recordings to meticulously arranged studio works. Hallmarks include inventive song structures, literate or introspective lyrics, and a willingness to blend elements of punk, post-punk, folk rock, and psychedelia. Over time, the term has come to describe both an approach to making music and the broad cluster of styles that grew from the independent rock underground.

Instrumental is music created and performed without sung lyrics, placing the expressive weight on melody, rhythm, harmony, and timbre produced by instruments. As an umbrella practice it appears in many cultures, but its modern identity cohered in Baroque-era Europe when purely instrumental forms such as the sonata, concerto, and dance suites began to flourish. Since then, instrumental thinking—developing motives, structuring form without text, and showcasing timbral contrast—has informed everything from orchestral music and solo piano repertoire to post-rock, film scores, and beat-driven electronic styles. Instrumental works can be intimate (solo or chamber) or expansive (full orchestra), narrative (programmatic) or abstract (absolute music). The absence of lyrics invites listeners to project imagery and emotion, making the style a natural fit for cinema, games, and contemplative listening.

Instrumental hip hop is a producer-driven form of hip hop that foregrounds beats, textures, and sampling rather than rapping. It typically centers on loop-based drum patterns, chopped samples from soul, jazz, funk, and library records, and a head‑nodding groove designed for deep listening as much as for DJs and MCs. The style emphasizes rhythm, timbre, and mood—swinging drums, dusty vinyl crackle, and melodic fragments treated as musical motifs. While rooted in classic boom bap aesthetics, instrumental hip hop ranges from minimal and meditative to densely collaged and psychedelic, reflecting both crate-digging traditions and studio experimentation.

Jazz is an improvisation-centered music tradition that emerged from African American communities in the early 20th century. It blends blues feeling, ragtime syncopation, European harmonic practice, and brass band instrumentation into a flexible, conversational art. Defining features include swing rhythm (a triplet-based pulse), call-and-response phrasing, blue notes, and extended harmonies built on 7ths, 9ths, 11ths, and 13ths. Jazz is as much a way of making music—spontaneous interaction, variation, and personal sound—as it is a set of forms and tunes. Across its history, jazz has continually hybridized, from New Orleans ensembles and big-band swing to bebop, cool and hard bop, modal and free jazz, fusion, and contemporary cross-genre experiments. Its influence permeates global popular and art music.

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.

Lo-fi hip hop is a mellow, sample-driven offshoot of hip hop that emphasizes warm, imperfect textures, simple loops, and relaxed grooves over virtuosic rapping or dense production. Producers often foreground tape hiss, vinyl crackle, and bit-depth artifacts to evoke a cozy, worn-in feeling that complements the genre’s minimal, repetitive structures. Built from boom-bap drum programming, jazzy chord progressions, and short melodic motifs, lo-fi hip hop typically functions as instrumental background music for reading, studying, or unwinding. Its aesthetics are closely tied to internet culture—especially 24/7 livestreams and anime-inspired visuals—making it one of the most recognizable “ambient hip hop” sounds of the streaming era.

Mallsoft is a subgenre of vaporwave that magnifies the sound and ambience of shopping malls, corporate lobbies, food courts, and retail soundtracks. It often loops, slows, and filters archival easy listening, smooth jazz, or library music to simulate the dreamlike experience of wandering an empty mall. The style foregrounds spatial illusion and consumer nostalgia: wide reverbs, distant PA announcements, and fountain or escalator noise create a glossy yet uncanny, hyper-commercial environment. Rather than rhythmic drive, mallsoft prioritizes mood, texture, and the sensation of endless browsing in a perpetually pristine retail space.

New age is a largely instrumental, mood-driven genre that emphasizes calm, spacious textures and a sense of spiritual or contemplative uplift. It blends gentle electronic timbres, acoustic instruments, and global/folk influences to create immersive soundscapes intended for relaxation, meditation, and introspection. Hallmarks include slow tempos or free time, long sustaining pads, modal and consonant harmonies, nature field recordings, and unobtrusive rhythms. The music often avoids dramatic tension in favor of openness and continuity, conveying themes of inner peace, nature, and the transcendent.

New jack swing is a late‑1980s fusion of contemporary R&B vocal harmony and melodies with hip‑hop’s drum programming, sampling aesthetics, and street attitude. It is defined by swung, hard‑hitting drum‑machine grooves (often with gated snares), bright synth stabs and bass, and a slick, dance‑oriented production style. Producers and vocal groups combined rap verses or talk‑style ad‑libs with smooth, hook‑forward choruses, making the sound equally suited for radio and choreography‑heavy performances. The style dominated U.S. pop and R&B charts from the late 1980s into the early 1990s, influencing mainstream pop as well as the first waves of K‑pop and shaping the trajectory of 1990s contemporary R&B.

New wave is a post-punk, pop-forward movement that blends the immediacy of punk with glossy pop hooks, danceable rhythms, and an art-school sensibility. Defined by crisp, often chorused guitars, prominent bass, steady four-on-the-floor or disco-inflected drums, and increasing use of synthesizers and drum machines, it channels irony and modernist themes into tight, radio-ready songs. Vocals tend to be cool or arch, lyrics frequently explore urban life, technology, alienation, and romance, and production is bright, spacious, and stylized. While stylistically diverse—from guitar-jangle and power-pop sheen to synth-driven minimalism—new wave is unified by its emphasis on craft, melody, and a sleek, contemporary aesthetic that helped bridge punk’s DIY energy with mainstream pop and dance culture.

Old school hip hop is the earliest commercially recorded era of hip hop, emerging from Bronx block parties in the late 1970s and reaching its peak in the early to mid‑1980s. It centers on DJs isolating and extending the "break" of funk and disco records while MCs deliver party-rocking rhymes, crowd call‑and‑response, and braggadocio over steady 4/4 grooves. The sound is rhythm-first: looped breakbeats, handclaps, simple bass ostinatos, and—by the early 1980s—Roland TR‑808 patterns and rudimentary synthesizer lines, especially on electro-influenced tracks. Lyrically, it ranges from playful party chants to early social commentary. Culturally, it’s inseparable from the four elements—DJing, MCing, b‑boying, and graffiti—and from the DIY energy of park jams and sound-system culture.

Pop is a broad, hook-driven style of popular music designed for wide appeal. It emphasizes memorable melodies, concise song structures, polished vocals, and production intended for radio, charts, and mass media. While pop continually absorbs elements from other styles, its core remains singable choruses, accessible harmonies, and rhythmic clarity. Typical forms include verse–pre-chorus–chorus, frequent use of bridges and middle-eights, and ear-catching intros and outros. Pop is not defined by a single instrumentation. It flexibly incorporates acoustic and electric instruments, drum machines, synthesizers, and increasingly digital production techniques, always in service of the song and the hook.

Post-rock is a style that uses traditional rock instrumentation—guitars, bass, drums, and often piano or strings—to create expansive textures, evolving soundscapes, and dynamic arcs rather than conventional verse–chorus songs. It emphasizes timbre, atmosphere, and gradual development: clean or lightly overdriven guitars drenched in delay and reverb, cyclical ostinatos, layered crescendos, and pronounced quiet–loud dynamics. Vocals, if present, are often sparse, wordless, or treated as another textural layer. The genre draws heavily from ambient, minimalism, krautrock, progressive and space rock, shoegaze, noise rock, and experimental practices, yielding music that can feel cinematic, contemplative, and emotionally cathartic.

R&B (Rhythm and Blues) is a vocal- and groove-centered popular music tradition that blends blues tonality, jazz harmony, and gospel-inflected singing with a steady backbeat. It emphasizes expressive lead vocals, call-and-response, lush harmonies, and danceable rhythms. From its 1940s roots in African American communities to its later evolutions, R&B has continually absorbed and reshaped surrounding sounds—from jump blues and swing in the early days to soul, funk, hip hop, and electronic production in the contemporary era. Today, R&B ranges from intimate, slow-burning ballads to club-ready tracks, all tied together by a focus on feel, melody, and vocal performance.

Soul is a genre of popular music that blends the spiritual fervor and vocal techniques of African‑American gospel with the grooves and song forms of rhythm & blues and the harmonic palette of jazz and blues. It is defined by impassioned, melismatic lead vocals; call‑and‑response with backing singers; handclaps and a strong backbeat; syncopated bass lines; and memorable horn or string riffs. Typical instrumentation includes drum kit, electric bass, electric guitar, piano or Hammond organ, horns (trumpet, saxophone, trombone), and sometimes orchestral strings. Lyrically, soul ranges from love and heartbreak to pride, social commentary, and spiritual yearning. Regionally distinct scenes—such as Detroit’s Motown, Memphis/Stax, Muscle Shoals, Chicago, New Orleans, and Philadelphia—shaped different flavors of soul, while the style’s emotional directness and rhythmic drive made it a cornerstone of later funk, disco, contemporary R&B, and hip hop.

Synthwave is a retro-futurist electronic genre that revives and reimagines the sound, texture, and visual culture of 1980s film scores, television themes, arcade games, and synth-pop. Characterized by analog-style synthesizers, arpeggiated basslines, neon-soaked melodies, and gated-reverb drums, it blends nostalgia with cinematic drama. Substyles include the uplifting, driving "outrun" sound, the softer and romantic "dreamwave/chillsynth," and the heavier, horror-tinged "darksynth." Typical sound palettes reference instruments like the Roland Juno series, Yamaha DX7, Oberheim and Prophet polysynths, with drum machines such as the LinnDrum, TR-707, and 909 (or their modern emulations).

Trap is a subgenre of hip hop that emerged from the Southern United States, defined by half-time grooves, ominous minor-key melodies, and the heavy use of 808 sub-bass. The style is characterized by rapid, syncopated hi-hat rolls, crisp rimshot/clap on the backbeat, and cinematic textures that convey tension and grit. Lyrically, it centers on street economies, survival, ambition, and introspection, with ad-libs used as percussive punctuation. Production is typically minimal but hard-hitting: layered 808s, sparse piano or bell motifs, dark pads, and occasional orchestral or choir samples. Vocals range from gravelly, staccato deliveries to melodic, Auto-Tuned flows, often using triplet cadences.

Trip hop is a downtempo, atmospheric fusion of hip hop rhythm and sampling techniques with the textures of dub, soul, jazz, and ambient music. Emerging from the Bristol scene in the early 1990s, it favors slow, head‑nodding breakbeats, deep bass, and cinematic sound design. The style is characterized by moody harmonies (often in minor keys), woozy tape- and vinyl-derived timbres, and liberal use of delay and reverb. Vocals frequently alternate between intimate, breathy singing and spoken word/rap, and lyrical themes tend toward noir, introspective, and melancholic subjects. Strings, Rhodes pianos, turntable scratches, and field recordings are common, creating a shadowy, filmic vibe.

Underground hip hop is a loosely defined movement within hip hop culture that prioritizes artistic integrity, lyrical depth, and experimental or non-commercial production over mainstream trends. It is often associated with independent labels, DIY distribution, and regional scenes that cultivate distinctive aesthetics and voices. Musically, underground hip hop favors sample-rich, boom-bap or off-kilter drum programming, gritty textures, and unconventional song structures. Lyrically, it emphasizes complex wordplay, social commentary, personal storytelling, and abstract or avant-garde imagery. Culturally, it values community, crate-digging, and innovation, maintaining a skeptical stance toward commercial pressures.

Vaporwave is an internet-born microgenre and visual aesthetic that repurposes late‑20th‑century commercial sound—mu zak, smooth jazz, soft rock, synth‑pop, city pop, and corporate training tapes—into hazy, slowed, and looped collages. Its sound foregrounds pitched‑down samples, heavy reverb, tape hiss, vinyl crackle, and dreamy pads to evoke a mood between satire and sincere nostalgia. Beyond music, vaporwave is inseparable from its graphic language: Greco‑Roman busts, Japanese text, retro operating systems, chrome logos, palm trees, neon gradients, and “mall culture” architecture. The result feels like a haunted shopping mall: part critique of consumer capitalism, part wistful memory of media and retail spaces from the 1980s–2000s. Tempos are typically slow (roughly 60–90 BPM), harmonies tend toward lush seventh and extended chords, and rhythms range from barely perceptible loops to minimal, gated drum programming. Many tracks are short, vignette‑like studies in texture and mood.

Wave is an internet-born electronic genre that emerged in the mid‑2010s, blending half‑time trap rhythms with ambient pads, emotive minor‑key harmony, and dubstep-informed sound design. It favors atmosphere and mood over maximal aggression, often pairing wide, reverb‑washed textures with weighty 808 subs and sparse melodic leads. Tracks typically sit around 120–140 BPM with a half‑time feel (60–70 BPM perceived), featuring crisp hi‑hat flicks, roomy snares on beat three, and long, cinematic builds and breakdowns. Vocals, when present, tend to be ethereal phrases or chopped one‑shots used as textures rather than full verses. While rooted in online communities and labels/collectives, Wave gradually crossed over to physical club spaces, maintaining a balance between headphone introspection and dancefloor momentum.

Wonky is a lopsided, synth-forward strain of experimental hip hop and UK bass that emerged in the late 2000s. It is defined by off-grid, swaggering drum programming, rubbery sub-bass, and brightly detuned, pitch-bent lead synths that feel as if they wobble in and out of time. Producers often work around 70–80 BPM (or 140–160 BPM in half-time), using heavy swing, microtiming, and syncopation to create a drunken, stumbling groove. Sonically, it blends the head-nod of instrumental hip hop with the sound design sensibilities of IDM, the sub-weight of dubstep, and the neon melodicism associated with Bristol’s "purple" sound. The result is music that is both club-ready and headphone-detailed: playful yet moody, maximal in color but minimal in arrangement, and distinctly characterized by elastic rhythms and glossy, detuned synth textures.

Indie (short for “independent”) began as music made and released outside the major-label system, where a DIY ethos shaped everything from songwriting and recording to artwork and touring. As a sound, indie is eclectic but often features jangly or overdriven guitars, intimate or understated vocals, melodic basslines, and unvarnished production that foregrounds authenticity over gloss. It spans rock, pop, and folk while welcoming electronic textures and lo‑fi aesthetics. Lyrics typically focus on personal observation, small details, and wry self-awareness rather than overt virtuosity or spectacle. Beyond style, indie describes a culture: small labels and stores, college/alternative radio, fanzines/blogs, community venues, and scenes that value experimentation, individuality, and artistic control.

Soundtrack is music created to accompany and enhance visual media such as film, television, and video games. It includes original scores (instrumental or vocal music composed specifically for the picture) and, at times, curated compilations of pre-existing songs. Stylistically, soundtrack is a meta-genre that can encompass orchestral symphonic writing, jazz, electronic and synth-driven textures, choral forces, popular song, and experimental sound design. Its defining trait is functional storytelling: themes, motifs, harmony, rhythm, and timbre are shaped by narrative needs, character psychology, pacing, and editing. Common features include leitmotifs for characters or ideas, modular cues that can be edited to picture, dynamic orchestration for dramatic range, and production approaches that sit well under dialogue and sound effects. Because it must synchronize to picture, soundtrack often uses clear dramatic arcs, tempo maps, and hit points.

Rap is a vocal music style built on the rhythmic, rhymed, and often improvised spoken delivery of lyrics over a beat. It emphasizes flow, cadence, wordplay, and narrative, and is commonly performed over sampled or programmed drum patterns and loops. Emerging from block parties and sound-system culture in the Bronx, New York City, rap became the core vocal expression of hip hop culture alongside DJing, breakdancing, and graffiti. While it is closely linked to hip hop, rap as a technique and genre has also crossed into pop, rock, electronic, and global regional scenes. Musically, rap favors strong drum grooves (breakbeats, 808 patterns), sparse harmony, and loop-based structures that foreground the MC’s voice. Lyrically, it spans party chants and battle brags to intricate internal rhymes, social commentary, reportage, and autobiography.

Bass music is an umbrella term for a family of UK-born electronic styles that foreground powerful low-end frequencies and broken, syncopated rhythms. Emerging in the late 2000s as the borders between dubstep, UK garage, grime, and drum & bass blurred, it emphasizes sub-bass design, percussive swing, and sound-system impact. Rather than a single formula, bass music describes a fluid scene where producers pull from 2-step shuffle, jungle breakbeats, dub space, and house tempos to create tracks that are equally at home on underground dance floors and on headphones. Hallmarks include heavy mono sub at 40–60 Hz, half-time/ off-kilter grooves, skeletal arrangements, and judicious use of delay, reverb, and modulation.

Beat (also called beat music or the Mersey sound) is a British pop/rock style that emerged in the early 1960s, blending American rock and roll, rhythm & blues, and skiffle into tight, upbeat songs with a strong backbeat. Typical beat records feature jangling electric rhythm guitars, prominent two- and three-part vocal harmonies, concise melodic hooks, and danceable 4/4 grooves. Lyrics are usually direct and youthful, often about love, friendship, dancing, and everyday life. The style became central to the British Invasion, with bands from Liverpool and across the UK topping charts worldwide and reshaping global pop and rock.

New Weird America (NWA) is a loosely defined early‑2000s U.S. movement that revived and mutated psychedelic and folk traditions through a DIY, experimental lens. It blends psych folk, free folk, drone, and outsider Americana with lo‑fi recording aesthetics, extended improvisation, and a surreal, pastoral sensibility. Rather than a strict genre, NWA describes a network of artists, collectives, and small labels who favored open tunings and acoustic timbres alongside noise, field recordings, tape hiss, and communal performance practices. The results range from intimate, childlike songs to sprawling trance‑drone ritual, all united by a fascination with the “old, weird” folk imaginary filtered through contemporary indie and experimental cultures.

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.

Chill beats is a mellow, predominantly instrumental hip‑hop offshoot defined by relaxed tempos, loop‑based arrangements, and a warm, nostalgic sound palette. Producers favor vinyl crackle, tape hiss, gentle side‑chain swells, and soft saturation that evoke the feel of bedroom recordings and vintage media. Musically, it leans on boom‑bap drum sensibilities, jazzy seventh and ninth chords, and short, ear‑worm motifs rather than extended melodies or virtuosic solos. Tracks are concise, hypnotic, and unobtrusive—crafted to sit comfortably in the background while still rewarding close listening. Aesthetically it is closely tied to online culture: anime and study visuals, cozy/nighttime urban imagery, and continuous livestream “radio” formats popularized the style. The genre’s purpose‑built calmness has made it a go‑to soundtrack for studying, reading, coding, and winding down.

Chillhop is a mellow, sample-driven offshoot of instrumental hip hop that emphasizes laid‑back grooves, jazzy harmony, and warm, nostalgic textures. Producers favor boom‑bap-inspired drums, soft sidechain swells, tape hiss, and vinyl crackle to evoke a relaxed, intimate mood. Typically sitting around 70–92 BPM, tracks use loop‑based structures, Rhodes or piano chords with extended harmonies, and sparse melodic motifs on guitar, vibraphone, saxophone, or synths. The result is music designed for focus and calm—commonly associated with “beats to relax/study to”—that blends the rhythmic DNA of hip hop with the smoothness of downtempo and jazz.

Tropical (often called música tropical) is a broad Latin American dance‑music umbrella that grew from Afro‑Caribbean styles and big‑band arrangements. It emphasizes lively, percussion‑driven grooves, syncopated horn lines, piano montunos, tumbao bass patterns, and call‑and‑response vocals. The feel ranges from elegant ballroom danzón and bolero to the high‑energy drive of mambo, cha‑cha‑chá, salsa, cumbia, and merengue. While repertoire and instrumentation vary by substyle and country, a shared rhythmic DNA—rooted in the clave and Afro‑diasporic percussion—unites Tropical music across the Caribbean and the Americas.

Experimental folk blends the storytelling, acoustic instrumentation, and modal harmonies of traditional folk with exploratory techniques drawn from the avant‑garde, psychedelia, and electroacoustic practice. It privileges texture, timbre, and atmosphere as much as song form: drones, field recordings, tape hiss, non‑standard tunings, and extended techniques sit alongside fingerpicked guitars, dulcimers, harps, and hand percussion. Structures are often loose or through‑composed, rhythms may drift or fracture, and harmony can alternate between simple pentatonic/modal materials and stark dissonance. Lyrically, the style leans toward myth, landscape, folklore, and dream logic—frequently intimate and diaristic, yet surreal. Production ranges from lo‑fi, room‑microphoned immediacy to collage‑like studio assemblage, emphasizing a sense of place and the raw grain of sound.

Synthesizer (as a genre tag) refers to music that foregrounds the electronic synthesizer as the primary sound source, celebrating timbre design, sequenced patterns, and the tactile possibilities of analog and digital electronics. It spans from early modular explorations and Moog/Buchla demonstrations to Berlin School sequences, space-age textures, and virtuosic keyboard reinterpretations of classical and popular repertoire. Emphasis is placed on sound design (oscillators, filters, envelopes, modulation), repeating motifs, and textural development, often with minimal lyrics or none at all. While the instrument is used across countless styles, the "synthesizer" category highlights works where the identity, techniques, and sonorities of the synth itself are the core aesthetic focus.

Jazztronica is a hybrid style that fuses the improvisational language, harmony, and timbres of jazz with contemporary electronic music production and rhythms. It often balances live instrumentation—such as saxophone, keys, bass, and drums—with programmed beats, sampling, and synthesis. Producers and bands in this genre draw from jazz-funk, acid jazz, and fusion, then layer in elements of downtempo, house, hip hop, broken beat, and IDM. The result ranges from head‑nod, beat‑driven tracks to club‑leaning grooves and cinematic, atmospheric pieces. Hallmarks include extended jazz chords, swung or syncopated drum programming, elastic basslines (both electric and synthesized), and textural sound design that supports improvisation and groove.
