G likes to create issues. I'm thinking the key here will be an interval based system.

Trying to think of where to start, here are the intervals for all the chords we currently use. Each chord's intervals are based off the starting note. 1=semitone, T=tonic

Chords Major Triad = T, 4, 7 Minor Triad = T, 3, 7 Major 7 = T, 4, 7, 11 Minor 7 = T, 3, 7, 10 Dim triad = T, 3, 6

Scales: Major = T, 2, 4, 5, 7, 9, 11 Natural Minor = T, 2, 3, 5, 7, 8, 10
