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.

Afro-Cuban jazz (often historically called Cubop) is a fusion of Afro-Cuban rhythmic traditions and North American jazz harmony, melody, and improvisation. It sets jazz writing and soloing inside the matrix of the clave, combining straight-eighth Afro-Cuban grooves (mambo, rumba, son montuno, danzón) with big-band and bebop vocabulary. Hallmarks include piano montunos (guajeos), tumbao bass lines, horn mambos and moñas (syncopated riffs), and a percussion section of congas, bongos, timbales, cowbell, and claves. The result is music that is harmonically sophisticated yet dance-driven, balancing arranged horn passages with open sections for improvisation, and emphasizing call-and-response and layered polyrhythms.

Alternative pop is a strand of pop music that keeps the melodic accessibility of mainstream pop while foregrounding unconventional songwriting, left‑field production, and an indie or art‑driven sensibility. It often blends acoustic and electronic timbres, juxtaposes intimate vocals with textural sound design, and favors mood, concept, and experimentation over radio‑formula structures. Hooks remain central, but they may sit within atypical forms, lo‑fi palettes, off‑kilter rhythms, or cinematic arrangements. Lyrically, alternative pop tends toward introspection, ambiguity, and subcultural reference points, addressing identity, technology, and contemporary alienation as frequently as classic pop themes like romance.

Alternative rock is a broad umbrella for guitar-based rock that emerged from the independent and college-radio scenes as a counterpoint to mainstream, commercial rock. It blends the energy and ethos of punk with the textural and songwriting experiments of post-punk, new wave, jangle pop, and noise rock, often foregrounding introspective or socially aware lyrics. Across its many strains—from the melodic minimalism of college rock to the loud-quiet-loud dynamics of grunge and the artful experimentation of Radiohead-era modernism—alternative rock prioritizes authenticity, sonic individuality, and a do-it-yourself approach. Its sound ranges from chiming, chorus-laden clean guitars to abrasive distortion and feedback, supported by straightforward rock rhythms or off-kilter grooves, and production that can be either raw and live-sounding or polished yet unconventional.

Filmi is the song tradition of Indian cinema, encompassing Hindi, Tamil, Telugu, Bengali, and other regional film industries. It is built for on-screen storytelling and "playback" singing, where actors lip-sync to pre-recorded vocals. Stylistically, filmi blends raga-informed melodies from Hindustani and Carnatic classical music with Indian folk forms, devotional currents (ghazal, qawwali, bhajan), and an evolving palette of Western popular idioms—big band, jazz, rock, disco, synth-pop, and EDM. Arrangements often feature lush orchestration, prominent melodic hooks, and dramatic modulations, supporting narratives of romance, devotion, comedy, and spectacle. As one of the most-heard musical practices in South Asia and its diaspora, filmi has defined the sound of commercial Indian culture for nearly a century while continually adapting to technology, audience taste, and cross-cultural exchange.

Funk metal is a high-energy fusion that marries the syncopated grooves and slap-driven bass of funk with the distorted riffs, power, and aggression of heavy metal and hard rock. Characterized by percussive guitar work (often using wah/envelope filtering and muted strums), tight, syncopated drum patterns, and virtuosic, popping/slapping electric bass, the style favors rhythmic interplay and punchy dynamics over dense harmonic movement. Vocals range from soulful singing to shouted chants or half-rapped cadences, with lyrics that can be humorous, satirical, or socially observant. The result is music that is both danceable and heavy, inviting mosh-pit intensity while retaining the elastic, body-moving feel of funk.

Happy hardcore is a fast, euphoric branch of the early UK rave continuum characterized by brisk tempos, 4/4 kicks, bright piano stabs, supersaw leads, and pitched-up “chipmunk” vocals. It emphasizes major-key harmony, catchy melodies, and ecstatic breakdowns, aiming for maximum uplift on the dancefloor. Compared to darker hardcore and gabber, happy hardcore favors feel-good hooks, singalong choruses, and sentimental atmospheres while retaining the relentless energy and drive of hardcore techno.

Hard rock is a loud, riff-driven style of rock music built around heavily amplified electric guitars, a powerful rhythm section, and assertive vocals. Songs typically center on memorable, blues-based guitar riffs, strong backbeats, and energetic, often shouted or belted choruses. The genre emphasizes power, groove, and visceral impact over intricate harmony or extended improvisation. Distortion, power chords, pentatonic melodies, and call‑and‑response between vocals and guitar are core traits, while lyrical themes often explore rebellion, lust, swagger, escape, and cathartic release.

Hardcore hip hop is a confrontational, uncompromising strain of rap defined by aggressive vocal delivery, hard-hitting drum programming, and stark, sample-driven production. It prioritizes intensity over gloss, often minimizing melody in favor of dense drum breaks, sirens, noise textures, and dissonant stabs. Lyrically, it spans street reportage, social realism, political critique, and battle-ready braggadocio. The aesthetic foregrounds rawness—distorted drums, clipped samples, shouted hooks, and posse energy—while drawing deeply from funk and soul breakbeats, DJ techniques, and the boom-bap tradition.

Heavy metal is a loud, guitar-driven style of rock defined by heavily distorted riffs, thunderous drums, and powerful vocals. Its musical language emphasizes minor modes, modal (Aeolian, Phrygian) riffing, and energy over groove, often featuring virtuosic guitar solos and dramatic dynamic contrasts. Emerging from late-1960s blues rock and psychedelic experimentation, heavy metal codified a darker, heavier sound with bands like Black Sabbath, Deep Purple, and Led Zeppelin. The genre values weight, intensity, and grandeur—whether through plodding, doom-laden tempos or galloping, high-energy rhythms—paired with themes that range from personal struggle and social critique to fantasy, mythology, and the occult.

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.

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.

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

Nu metal is a hybrid style that fuses the weight and riff-centric attack of heavy metal with hip‑hop rhythms, turntablism, funk bounce, and the angst‑laden melodicism of alternative rock. It favors down‑tuned, percussive guitar work, punchy bass lines, and groove‑heavy drum patterns over extended solos. Vocals often switch rapidly between rapped verses, shouted/screamed passages, and soaring melodic choruses. Production tends to be glossy yet bass‑forward, frequently incorporating DJ scratches, samples, electronic textures, and syncopated, hip‑hop‑influenced beats. Lyrical themes commonly explore alienation, trauma, social pressure, and catharsis. The result is an accessible but aggressive sound that emphasizes groove, dynamics, and hook‑writing as much as heaviness.

Rock is a broad family of popular music centered on amplified instruments, a strong backbeat, and song forms that foreground riffs, choruses, and anthemic hooks. Emerging from mid‑20th‑century American styles like rhythm & blues, country, and gospel-inflected rock and roll, rock quickly expanded in scope—absorbing folk, blues, and psychedelic ideas—while shaping global youth culture. Core sonic markers include electric guitar (often overdriven), electric bass, drum kit emphasizing beats 2 and 4, and emotive lead vocals. Rock songs commonly use verse–chorus structures, blues-derived harmony, and memorable melodic motifs, ranging from intimate ballads to high‑energy, stadium‑sized performances.
