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

}🟢resolve_chord(chord)
Resolve a chord to spelled notes, frequencies, MIDI, and recommended scales.

}🟢generate_voicing(chord, style, octave, voices, previousNotes, ...)
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(progression, technique, key)
Reharmonize a progression. Techniques: tritone_sub, ii_v_insertion, modal_interchange, diminished_passing, secondary_dominant, chain_of_dominants, coltrane_changes, backdoor (or auto).
