harmony — a reasoning module

Four-part writing marked as a harmony teacher marks it, as a DKE Python module you compile into your own store. You record an exercise's voices, key and chords; it names every consecutive fifth and octave, crossed voice, spacing fault, note outside a voice's range or the key, and the reading of every chord, and withdraws each mark when you correct the note it rests on. It checks a melody's rhythm against its bars, and calculates equal-tempered frequencies, cents, set classes, twelve-tone matrices and Euclidean rhythms.
