Key & Tempo:
- Key: A minor (can be adapted to D minor or Dorian on request)
- Tempo: 70 BPM (range 60–80 BPM recommended)
Short Mix Structure (2:30) — clear section markers for editing and narration:
Intro (0:00–0:20) — Atmosphere and space
- Low ambient pad/drone (sub 60–250Hz) opens with slow filter sweep; airy low-mid rumble sits under everything (-18 dB). Long reverb tails on ambient layer.
- Occasional processed bowed cello pulses (A1–A2) bowed and lightly distorted/filtered, slow rhythm: quarter-note pulses with soft saturation to add texture.
- Very sparse reverse-reverb hits (filtered under 800Hz) to imply motion and tension.
- Leave 200–4000 Hz clear for voice; high shelving only on top air elements.
Core Loop (0:20–1:30) — Main motif and subtle pulse
- Foundation: pad drone (sub) + soft processed bass pulses (low bowed cello or analog sub) playing root and occasional chromatic approach notes.
- Pulse: brushed snare/clicks on off-beats and very soft low-transient kick (sampled, low sustain). Keep percussion -20 to -26 dB; transient suppressed.
- Melodic hints: filtered electric piano / toy piano (high-pass at ~300Hz) plays sparse 2–4 bar motifs. Motif example (A minor space, use minor 2nds/diminished color):
Motif A (2 bars): A4 (eighth), A#4/Bb4 (minor 2nd, sixteenth), E5 (dotted eighth), C5 (quarter) — leave silence after phrase.
Motif B (2 bars response): E4 (half), D#4/Eb4 (diminished inflection, dotted quarter), C5 (eighth) — space to breathe.
- Occasional high, bell-like synth hits with long decay appear every 8–12 bars (pan wide, -10 to -12 dB).
- Use call-and-response: motif plays on the left; distant muted bell echoes on the right with heavy reverb.
- Keep motifs sparse; most bars contain space for narration.
Tension Build (1:30–2:10) — subtle rise, still voice-friendly
- Increase reverb tails slightly and introduce a filtered riser under 200–800Hz (low-pass sweep then open slightly) to create implied motion without clashing with voice.
- Add suspended or diminished harmonic color: introduce Csus2 → A minor (add b5 approaches) in low pads.
- Bring in a complementary processed lead (very low-volume) that repeats a short diminished 2-bar figure; treat with heavy convolution reverb and low-pass to keep it ethereal.
- Percussion: very light shuffle on brushes or soft clicks increases slightly in density but remains low-transient and low-volume (-22 to -28 dB).
Outro (2:10–2:30) — release and fade
- Remove percussion at ~2:18 so the final 8–12 seconds are ambient drone + a single toy-piano motif drenched in reverb.
- Low-pass automation filters the pad down; final 6–8s are sub-pad + long reverb bell tail fading out for easy editorial crossfade.
Extended Mix (4:00) — more variations, longer tension arc
- Intro 0:00–0:20 same, then Core Loop repeats with subtle variations x2 (0:20–2:00).
- Tension Build extended 2:00–3:20: slowly introduce secondary motifs, slightly more frequency movement under 200–800Hz, additional bowed-cs
