About this skill

Score Composer

Use this when the work must exist as music, not only as a generative MP3.

The score is the canon. Lyria and Suno are performance/promo lanes. Sheets and tabs compile from the score. Never transcribe a generative MP3 and call that the work.

Trigger

Activate when the user asks to:

  • compose piano, chamber, orchestra, or guitar works;
  • produce high volume of actual pieces;
  • write sheets, tabs, melody/rhythm in correct formats;
  • generate with Google Lyria next to Suno or live playing;
  • get a high-quality MP3 from simulation or human emotion.

Pipeline

brief → motif/form → compact score.txt → validate → compile
     → MusicXML / MIDI / ABC / piano sheet / guitar tab
     → choose ONE audio lane

1. Write the composition, not the prompt

Before any generation:

  • Listener moment and emotional contract.
  • Motif: 3–6 notes the piece cannot lose.
  • Form: bar counts, not vibes.
  • Key, meter, tempo, negative space.
  • One image system. One turn.

Then encode the piece in the compact DSL at:

~/agentic-music-producer-os/catalog/<slug>/score.txt

@title Window Latch
@kind piano
@key D minor
@time 4/4
@tempo 68
@thesis ...
@motif descending A-F-D
@form 16-bar miniature

[Piano]
1 RH: A4q F4q D4h
1 LH: D3h A2h

Durations: w h q e s plus optional .
Rests: rq rh
Chords: [D5A4]q
Voices: RH LH P for monophonic parts.

2. Validate and compile

python ~/agentic-music-producer-os/scripts/score_cli.py validate catalog/<slug>/score.txt
python ~/agentic-music-producer-os/scripts/score_cli.py compile catalog/<slug>/score.txt --preview --mp3

Required artifacts:

File Job
.musicxml Canon for MuseScore / Dorico / Sibelius
.mid Live play, DAW, sample library
.abc Compact interchange
.piano.txt Immediate readable piano sheet
.tab.txt Guitar melody tab
lyria-prompt.md Timed Lyria packet
suno-bridge.md Existing Suno lane, one Create only

Publication-quality PDF: open the MusicXML in MuseScore 4 and export. Do not claim a PDF exists unless MuseScore or LilyPond actually wrote it.

3. Audio lanes (pick one; do not blur them)

  1. Live human — highest emotion. Print the sheet or send MIDI to a keyboard.
  2. High simulation — MIDI into Pianoteq / NotePerformer / Spitfire / MuseScore + good soundfont. This is the honest "highest quality simulation."
  3. Local preview MP3 — --preview --mp3 additive piano. Proof of hearing only.
  4. Lyria 3 — Google generative performance. Audio is 44.1 kHz stereo. It will not match the score note-for-note.
  5. Suno — promotional/vocal/commercial. Existing one-Create policy. Load suno-prompt-architect + music-taste-review first.

Lyria models:

  • lyria-3-clip-preview — 30s MP3, iterate here first
  • lyria-3-pro-preview — full piece, MP3 or WAV
python ~/agentic-music-producer-os/scripts/lyria_cli.py status
python ~/agentic-music-producer-os/scripts/lyria_cli.py packet catalog/<slug>/build/lyria-prompt.md --wav
# only after explicit "generate with Lyria" AND a Gemini key in the process
python ~/agentic-music-producer-os/scripts/lyria_cli.py generate catalog/<slug>/build/lyria-prompt.md --out catalog/<slug>/build --authorize

Never paste API keys. Load GEMINI_API_KEY from Infisical/registry. Never invent a take.

4. Volume factory

Greatest volume of works means many validated scores, not many unreviewed MP3s.

Cadence for a session:

  1. Choose a series thesis (example: 12 piano nocturnes, one motif family).
  2. Write 1 complete miniature (8–32 bars) per cycle.
  3. Validate + compile before the next piece.
  4. Keep only pieces whose motif, turn, and ending are distinct.
  5. Batch-render MIDI later through the high-simulation lane.
python ~/agentic-music-producer-os/scripts/score_cli.py catalog

5. Taste for scores

Hard vetoes:

  • no motif;
  • bar lengths wrong;
  • unplayable piano stretches or guitar melody off the instrument;
  • named-artist imitation;
  • claiming Lyria/Suno audio is the score;
  • claiming concert-hall MP3 quality from the local preview synth.

A piece is done when:

  • validate is clean;
  • MusicXML + MIDI + sheet + tab exist;
  • the ending is authored;
  • the next move is one audio lane, named.

Report

Return:

  1. title + one-sentence thesis;
  2. catalog path;
  3. verified artifact paths only;
  4. which audio lane is next;
  5. no quality claim without a real file and, for "high quality," the actual renderer used.
