Mode
F Dorian
The F Dorian mode — F G Ab Bb C D Eb — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
F Dorian is the natural minor with one note changed — the 6, D. 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.
