Scale Boxes — Terz Guitar

Choose a root note — the boxes for all 24 types are drawn with roots flagged.

The Terz Guitar scale reference, position first: choose a root and one of 24 types, and get boxes drawn on the GCFA#DG grid with the roots flagged in every one.

The GCFA#DG grid is fourths with one major third at A#–D, so every box crossing that pair shifts up a fret — the maps draw the kink where it happens instead of pretending the neck is regular.
