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

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.

Drum and bass (DnB) is a fast, rhythmically intricate form of electronic dance music centered on breakbeats at roughly 160–180 BPM and powerful, sub‑heavy basslines. It grew out of the UK’s early ’90s rave and jungle scenes, combining chopped funk breaks (most famously the Amen break), dub and reggae sound‑system aesthetics, hip‑hop sampling, and techno’s futurist sound design. Across its many substyles—liquid funk’s soulful harmonies, techstep and neurofunk’s cold, machine‑like bass engineering, jump‑up’s hooky bass riffs, atmospheric DnB’s pads and space—drum and bass remains a DJ‑oriented, dancefloor‑driven genre that prizes tight drum programming, deep low end, and precise arrangement for mixing.

Minimal drum and bass is a stripped-down branch of drum and bass that emphasizes space, restraint, and precision over maximal density. Rather than thick layers of breaks and bass, it uses skeletal drum patterns, heavyweight sub-bass, and micro-detailed sound design to create tension and depth. Typical tempos sit around 170 BPM, but the rhythmic feel often alternates between full-time and halftime, with ghost notes, syncopated hi-hats, and carefully placed percussive accents. Production draws on the aesthetics of minimal techno and dub techno—dry, focused transients balanced with dubwise delays and reverbs that are tightly EQ’d to preserve headroom. The result is music that feels spacious, hypnotic, and controlled, yet still club-ready.

Techstep is a dark, stripped‑down branch of drum and bass that emerged in the UK during the mid‑to‑late 1990s. It favors rigid, two‑step drum patterns, stark sci‑fi atmospheres, and heavily processed "Reese"-style basslines over the funkier break-chopping of earlier jungle. The aesthetic is cold, mechanical, and dystopian: metallic snares, tightly quantized rhythms, and industrial textures combine with minor, dissonant stabs and eerie pads. Typical tempos sit around 170–175 BPM, with emphasis on sub‑bass weight, tension, and precision rather than melodic complexity.

Bass music is an umbrella category that emphasizes heavy, foregrounded low‑frequency content—whether a booming kick drum, a sub‑bassline, or both. It spans electronic dance music and hip hop lineages from the 1980s onward and is less about one fixed rhythm than about putting the bass spectrum at the center of the mix. Producers typically sculpt the bass using synthesizers, samplers, and drum machines—famously the Roland TR‑808—along with modern soft synths and sub‑enhancement tools. Because it is a broad label, bass music can range from half‑time hip hop swing to four‑on‑the‑floor house pulses and breakbeat frameworks, but in every case the arrangement, sound design, and mix are built to make the low end the driving force.
