Scale Boxes — Guitarrón
Choose a root note — the boxes for all 24 types are drawn with roots flagged.
The Guitarrón scale reference, position first: choose a root and one of 24 types, and get boxes drawn on the ADGCEA grid with the roots flagged in every one.
The grid under these maps is the standard one, so the boxes are the boxes guitarists already know — the ADGCEA grid.
