Chord Shapes — Loog
Start from a root note: the full quality list unfolds as GBE neck shapes.
The Loog chord reference, shape first: pick a root, then any of 21 qualities, and get every charted grip on the GBE grid with frets, fingers, and audio.
Loog strings are guitar strings 3-2-1 (G-B-E) — every shape here is the top of the matching guitar shape, so it all transfers when you move up to six strings.
