G Locrian

The G Locrian mode — G Ab Bb C Db Eb F — shown across the guitar neck.

Swipe the neck sideways to see the higher frets.

G Locrian is the natural minor with the b2 and b5 — Ab and Db. Those are the notes that give it its character.

The tool shows this from its parent key, Ab major, with G marked as where Locrian begins, the same seven notes centered on Ab.
