This file is byte-identical to the first copy the registry indexed. Same content hash, so the same checks give both the same grade.
listening-to-music from oaustegard/claude-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add oaustegard/claude-skills/listening-to-music@v0.2.0Pins v0.2.0 in mdr.lock. Pin the fingerprint instead.

Listen to generated music by measuring it and by reading it as sheet music: render Strudel code or record a Web Audio page through the real engine in headless Chromium, then read spectrograms, pYIN pitch lines, chroma, roughness and semitone-rub meters; engrave notes as a score with beat-by-beat harmony; transcribe a melody from audio; read MusicXML/MIDI/ABC or a score image into notes and into Strudel code. Use to check whether generated music sounds right or better (before/after a change)…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Listening to music
Claude hears nothing, but it can render audio in the real engine and measure it. Set up the loop
**render → look → measure → change one thing → re-render**, and keep a table of the numbers per
version. A version is better when a number you chose beforehand moves by more than the
take-to-take noise, and the spectrogram shows the same thing.
Requirements: Node with `playwright` and Chromium (preinstalled in Claude Code on the web),
Python with `librosa soundfile scipy matplotlib pillow`, and for sheet music
`music21 verovio mir_eval cairosvg`
(`pip install --break-system-packages librosa music21 verovio mir_eval cairosvg`). The first render installs `@strudel/web` into
`~/.cache/listening-to-music/`. All scripts live in `scripts/`; run them with `--help` or read the
docstring for options.
## 1. Render
```bash
S=/path/to/listening-to-music/scripts
node $S/render_strudel.mjs loop.js --out v1.wav --seconds 40 --warmup 4 # Strudel code
node $S/record_page.mjs page.html --click "#power" --out v1.wav --seconds 40 --warmup 8 \
--query "station=house" --eval "window.__fm.setSeed(7)" # any Web Audio page
```

How to install
mdr add oaustegard/claude-skills/listening-to-music@sha256:9958c55fc3f19189The line at the top of this page pins the label v0.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
