G# Locrian

The G# Locrian mode (also written Ab) — G# A B C# D E F# — shown across the guitar neck.

Also written Ab Locrian. Ab and G# are the same pitch, though spelling it from Ab would need double accidentals (Ab Bbb Cb Db Ebb Fb Gb), which is why G# is the name in use.

Swipe the neck sideways to see the higher frets.

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

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