Mode Chord Viewer

Input

Single: C, D, Eb, F# — Multi: [[C,D,E],[F#,G,A]]. Right hand octave 4, left hand octave 3.
Interval offsets from each mode step. e.g. [[0,2,4]] = 1st+3rd+5th. [[0,2],[1,3]] = two chords per step.
Same format. Offsets wrap to the next octave when they exceed the mode length.
