If more than one pitch shares the same chordStep such as the third in (C, E-, E, G), then only the first will appear in the dictionary. The dictionary will be ordered by the order of pitches in the Chord. More efficient than calling [getChordStep(x) for x in range(1, 8)] which would be O(n^2) on number of pitches. Requires `root()` to be defined. >>> ch = chord.Chord('C4 E4 G4 B4 C5 D5') >>> chord.tools.allChordSteps(ch) {1: , 3: , 5: , 7: , 2: } )rootdiatonicNoteNumpitches)rroot_dnnout_map thisPitchdiatonicDistances /Users/tedpeters/Documents/Projects/Claude Projects/Misc Tools/notename-sheets/.venv/lib/python3.11/site-packages/music21/chord/tools.py allChordStepsrs^*vvxx'H&(GY22 &6AQF!K 7 * *(1G$ % N__main__)rrrr ) __doc__ __future__rtypingt TYPE_CHECKINGmusic21rrr__name__mainTestrrr!s#"""""?< zNNNGr
