audio-only jungle tracks built bottom-up from AC instruments — chopped breakbeats, deep dub sub, reggae skank, dub sirens. fast drums, half-time feel: the kit sprints, the groove saunters, the MC rides loose over the top.

opens on sunbreak as the first sub-format — sunlit / golden jungle, daytime-block-party energy rather than dark-club menace. warmer pads, melodic sub, playful skank. three variants ship together so the lane has range to prove itself.

these are beats for fía to rap over — the lane ships the instrumental; fía is the MC. the .txt next to each .np is a light spanish toast cue-scaffold (call-and-response stubs, section hooks), not a finished lyric. her voice is performance on top of the composition, recorded live, not synthesized.

the hybrid break #

jungle is, classically, built on a sample — the Amen break. pop's posture is bottom-up: compose from AC's own instruments, no top-down sampling. so the break here is a hybrid (per @jeffrey, 2026-05-16):

the groove is the AC percussion kit (percussion.mjs — the same kick/snare/hat/ride web + native notepat play) sequenced into chopped-Amen-style syncopation: displaced kicks, backbeat snare, ghost snares, busy shuffled hats, rolled phrase-end fills
a synthesized break-stab — a short bitcrushed/flanged snare-roll burst — fires at phrase ends as the genre nod, the chopped-tape texture, without ever sampling the Amen

no Winstons. no loop. it won't sound exactly like a chopped Amen — it sounds like AC playing jungle. that's the honest version of the form, and it's the research question the lane exists to answer.

format spec — sunbreak #

length: ~1:20–1:30
tempo: 165 BPM (range 160–175), felt in half-time (~82 perceived) so the toast sits loose over sprinting drums
key: sunlit — minor pentatonic with a major-third warmth (A / D / E roots by default). golden, not menacing
structure: intro (4) → roll-in (8) → drop 1 (16) → dub-break (8) → drop 2 (16) → out (4) bars
bed:
- break — hybrid AC-kit breakbeat, chopped + shuffled, half-time felt
- break-stab — synthesized bitcrush/flange snare-roll burst at phrase ends (the genre nod)
- sub — deep dub/reggae sub bass, long roots + offbeat push, ducked under the kick
- pad — warm golden chord pad (sinepower), slow attack
- skank — reggae offbeat chord stab (sinepower stab), the block-party bounce
- siren — sparse dub-siren / airhorn nods, AC pitch-swept synth
vocal: fía — live spanish ragga toast over the top. instrumental ships standalone; the toast is added by her, not by the renderer
output: single mp3 per track in out/<slug>.mp3. no video

variants #

three takes on sunlit jungle, one renderer, selected per-track:

jungleton — jungletón: jungle break with reggaeton / dembow tresillo woven into the kick + sub. spanish toast sits native. the live 2025 latin-club niche (Parzubanil)
raggasol — classic ragga jungle, sunlit: chopped break, dub sub, reggae skank, sirens. the purest jungle DNA, warmed up
rodando — liquid / rollers: rolling (not frantic-chopped) break, lush golden pads, musical chords. the most melodic — room to sing-rap

arrangement notation #

same convention as the dance + chillwave lanes — section markers as comments gate which bed layers fire:

# intro 4 [break-thin, sub]
A2:_*4 ...

# drop 1 16 [break, break-stab, sub, skank, pad, siren]
A4:_*2 C5:_*2 ...

# dub-break 8 [sub, siren, no-break]
...

bracket flags pass through to bin/render.mjs. unflagged sections inherit the style defaults.

pipeline #

bin/render.mjs — single-command renderer. mirrors the chillwave renderer: parse the .np score + section flags, layer the hybrid break / sub / pad / skank / siren, mix + peak-normalize → mp3.

node bin/render.mjs --slug raggasol
node bin/render.mjs --slug jungleton --style jungleton --bpm 168
node bin/render.mjs --slug rodando --layer break    # solo a layer
node bin/render.mjs all                              # render all three

one-command deliverable — --cover runs the whole chain: audio → colored-pencil illustration (gen-illy.mjs, gpt-image-2) → typographic cover composite (../dance/bin/cover.mjs --illustration) → cover art + ID3 tags muxed into the mp3 in one pass. the illustration is cached, so only the first run pays the gpt-image-2 cost; --force-art regenerates it. if the illy can't be made (no API key / offline) it falls back to the geometric cover.

node bin/render.mjs all --desktop --cover            # the full thing
node bin/render.mjs --slug raggasol --cover --force-art

cover illustration prompts live at <slug>.illy.txt (the rough-tooth / no-outline / 15°-hatch colored-pencil style, one sunlit sound-system emblem per track — no figures).
