Mode
F Phrygian
The F Phrygian mode — F Gb Ab Bb C Db Eb — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
F Phrygian is the natural minor with one note changed — the b2, Gb. 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.
