Continuing on from my previous post, I've made an application that tests 3, 4, 5 and 6-note chords outside of the typical major/minor format. Inspired by a similar listing of chords in Elliott Carter's harmony book, this app gives answers in pitch-class format; i.e. 0, 1, 2 refers to three notes all separated by semitones, while 0, 4, 7 refers to a major triad.
Please make sure you follow the instructions from the previous post:
