Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Tools (4)
🟢analyze_chord(chord, key, scale, convention)
Parse a chord into root, quality, intervals, and (with a key) roman numeral + function. Numerals use the jazz convention by default (Cmaj7 in Am = ♭IIIΔ7); both jazz and classical numerals are always returned in `numerals`, and other valid readings in `alternatives`. Pass `scale` to read a minor key as harmonic or melodic minor.
