FAITHFUL take of the row's style — PLAYFUL BELL AMBIANCE in B♭ major pentatonic, 88 BPM, the FOXFIRE family (§7.4). Dusk magic over the bog: a warm pad floor with caveCelesta sparks, EACH ECHOED ONCE ACROSS THE STEREO FIELD (the celesta panned ~100 left, its echo ~160 right), and a mischievous pentatonic pluck that imitates a spark then OUTRUNS it. Per §7.4's locked instance note, the major-pentatonic recontext rounds FOXFIRE's 7-flicker into the 6 (the 7th snaps to G), so the lights read softer and rounder — mischief, lights that might lead you off the path. Fully diatonic to the pentatonic (Bb C D F G — no E or A, so no tritone/leading tone, only glow); no chromaticism. CALM (ch0-3) is bed only: soft pad chords, an inner-voice rock, the sub once per two bars, and a few low facet glints with their single echoes — watching the lights. ACTIVITY L1 (ch4-5) is the bell spark + its single stereo echo — the design's defining gesture. ACTIVITY L2 (ch6-7) ADDS NEW MATERIAL, not volume: the chase pluck first imitates the spark's 5-6 lift then darts up the pentatonic in fast sixteenths, OUTRUNNING the bell, plus a soft counter-glint arp; the spark also broadens (augment×2) in A2 while the chase keeps overtaking it. DANGER is SUBTRACTIVE per the §3 note: the bed THINS (the warm inner/facet voices are removed, leaving only a hollow low pad pedal — warmth gone) as ch8-11 ADD a low pulse. DANGER L1 (ch8-9) is unease/the approach: a slow kick heartbeat under the cold pedal with a sparse guttering boom — real material, not near-silence. DANGER L2 (ch10-11) is a GENUINE intensity jump for active flee: a driving doubled kick, closer booms on the bar, and tightening hat ticks, the section a notch faster (96 BPM) — the lanterns going out one by one, the ground gone soft. Dread is abstract (warmth subtracted, pulse and density rising); no foley of mud/water/insects (that's the game's SFX/ambient soundscape, not the score).
