• analyze_chord ~253 tokens

Pass `scale` to read a minor key

  Instrument-ready voicing in a style; pass previousNotes for a voice-leading score.
• reharmonize ~132 tokens
  Reharmonize a progression. Techniques: tritone_sub, ii_v_insertion, modal_interchange, diminished_passing, secondary_dominant, chain_of_dominants, coltrane_changes, backdoor (or auto).
