F# Aeolian (Gb Aeolian) on Guitar
Aeolian is the natural minor scale — the plain sad one, the shadow twin of the major scale. The notes of F# Aeolian are F#, G#, A, B, C#, D, E. Its characteristic note is D — the flat 6th — the one note that gives this minor-type scale its colour.
It is the sound of most minor-key rock and pop: "Stairway to Heaven", "Losing My Religion", every power ballad. The flat 6th is what separates it from Dorian — where Dorian lifts, Aeolian sinks.
F# Aeolian across the whole neck
Over the drone, walk the flat 6th down to the 5th and feel it settle — that sigh is the natural minor signature.
