Suno Control Plan: The Rinse Light

Created after: `composition-brief.md` Created before: `guide-track.json`, MIDI, MP3 render, and `suno-prompt.md`

What Must Suno Obey?

72 BPM circular launderette pulse.
A minor tonal centre with F major chorus warmth and E suspended pressure.
Close dry female alto vocal.
Almost-spoken verse entrances.
A recognisable title-hook contour on "let the rinse light turn."
Chorus 2 must feel harmonically changed, not copied.
Final chorus must delay the title phrase rather than simply get bigger.
Sparse room-scale sound: muted acoustic pulse, low fluorescent hum, intimate vocal.

Which Source Leads?

Primary lead: lyrics and section tags. The story is object-led and must remain clear.

Secondary lead: vocal phrasing guide. It controls the title-hook contour, breath timing, changed harmonic return, and delayed final refrain.

Support lead: style prompt. It defines sonic world and exclusions.

Not leading today: custom model, My Taste, Extend, Cover, publishing, or any platform action. Dakota Vale voice can be selected only if John explicitly approves private Suno generation.

Guide Type Decision

Chosen type: vocal phrasing guide.

What would break without it: Suno may produce a fluent sparse folk song but flatten the study's actual lesson: repeated refrain transformed by harmonic timing and delayed entrance.

What Should Suno Be Free To Invent?

Natural final vocal timbre and expressive detail.
Guitar voicings and production texture.
Subtle bass support if it does not become full band.
Washer-room ambience and mix depth.
Minor melodic ornamentation around the guide.

What Must Be Excluded?

Real artist/reference names.
Obvious imitation of studied artists.
Dramatic crime-story reveal.
Glossy pop catharsis.
Full drum kit or stomp rhythm.
Cinematic synth swell.
Choir or arena ending.
