README

music-workflow-skills

**Claude Code skills that turn a recording into a band chart and an Ableton Live set — including the odd meters, modes and drones that other analysis tools flatten into 4/4 major/minor.**

Give Claude a song and its lyrics. It finds the pulse, sweeps for the meter, separates stems, transcribes the bass, names the mode, reads the chords, times the lyrics, and writes a chart a band can play from — then, if you want, rebuilds it in Live with the right time signature. Everything runs offline on an Apple Silicon Mac, and every step is a script with tests.

The skills

Skill	Use when
`song-analysis`	A recording has to become tempo, meter, key/mode, stems, bass line, chords per bar, timed lyrics, sections, or a band chart
`song-to-ableton`	You want a song rebuilt, covered or reinterpreted in Live — analysis feeding the build
`bass-transcribe`	You played bass (or sang a line) and want it as MIDI, a Live clip or a tab
`ableton-mcp`	Driving Live over MCP: tracks, clips, notes, devices, mixing, time signature — and the gotchas
`ableton-arrangement`	Arranging in Live: sections, bass and drum patterns in any meter, FX chains, dynamics

Why it's different

It finds meters it was never told about. Instead of choosing between 3/4 and 4/4, it sweeps every cycle from 2 to 25 pulses on the drum, bass and harmonic stems. 7/8, 11/8 and 5/4 come back with their grouping — 11/8 as 6+5, beat 1 counted from the kick.
It asks instead of guessing. When the evidence can't decide — two equally strong accents, a 2-bar phrase that could be one bar, an eighth-note pulse that doubles the DAW tempo — it stops and tells Claude exactly what to ask you.
It measures modes. Tonic from what the bass sustains, mode from bar-by-bar duels of
