Mode
A Dorian
The A Dorian mode — A B C D E F# G — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
A Dorian is the natural minor with one note changed — the 6, F#. That single note is what the mode sounds like; lean on it and the colour is obvious, avoid it and you are just playing minor.
