F# Aeolian

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

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

Swipe the neck sideways to see the higher frets.

F# Aeolian is the natural minor — same seven notes, same order. The mode name describes which chord you treat as home, not a different set of notes.

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