Mode
E Lydian
The E Lydian mode — E F# G# A# B C# D# — shown across the guitar neck.
Swipe the neck sideways to see the higher frets.
E Lydian is the major scale with one note changed — the #4, 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.
