Mode
F Mixolydian
The F Mixolydian mode — F G A Bb C D Eb — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
F Mixolydian is the major scale with one note changed — the b7, Eb. That single note is what the mode sounds like; lean on it and the colour is obvious, avoid it and you are just playing major.
