Mode
A Phrygian
The A Phrygian mode — A Bb C D E F G — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
A Phrygian is the natural minor with one note changed — the b2, Bb. 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.
