Palette

Every chord on every chromatic scale degree, for every key. Rows are keys (circle of fifths). The 108 columns are organised first by scale degree (1, b2, 2, b3, 3, 4, b5, 5, b6, 6, b7, 7) and then by chord quality on that degree (major, minor, dim, 7, maj7, m7, m7♭5, sus2, sus4).

This is not a chord progression — left to right is sorted by chord-quality structure, not by musical function. It's a sprawling chord dictionary, indexed by key. Most of these chords are notdiatonic to the row's key; reading horizontally is for spotting patterns, not for playing.
