このMCPでできること

Performs deterministic music theory operations including analysis, voicing, reharmonization, and conducting.

analyze_chord
Parse a chord into root, quality, intervals, and (with a key) roman numeral + function.

入力スキーマ
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['chord'], 'properties': {'key': {'type': 'string'}, 'chord': {'type': 'string'}}}
conduct_band
Arrange a 4-piece band from a natural-language prompt. Returns conductor tempo/groove, 4 lanes of note events, lead sheet, and base64 MIDI. Audio render (Csound → WAV) stays on local thiri-conductor-mcp / POST /v2/render.

generate_voicing
Instrument-ready voicing in a style. Tension symbols voice by seat substitution (arranging practice, not stacking): 9/b9/#9 replace the root, #11/13/b13 replace the 5th, the 3rd and 7th are untouched guide tones. Pass voices: 5 to promote the implied 9 of an 11/13 chord; pass previousNotes for a voice-leading score.

reharmonize
Reharmonize a progression. Techniques: tritone_sub, ii_v_insertion, modal_interchange, diminished_passing, secondary_dominant, chain_of_dominants, coltrane_changes, backdoor (or auto).
