Mode
B Mixolydian
The B Mixolydian mode — B C# D# E F# G# A — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
B Mixolydian is the major scale with one note changed — the b7, A. 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.
