The Circle of Fifths

Lydian Mode is a variation on the typical major scale. It also has a “happy” colour to it.

To play lydian mode on the piano, you can just play all the white notes, starting on an F
The mode consists of notes with the intervals: T-T-T-S-T-T-S
As an example, make sure that you have E at the top of the circle. You can see that in order to play an E lydian scale, you can just play a B major scale, but centring around the F.
To see what notes are in an E lydian scale, make sure that B is at the top of the circle. B major has lots of sharps: F#, C#, G#, D#, A#
Top play a song in E lydian, you would play all of the chords from the key of Bmajor, but centring around the E: E, F#, G#m, A#dim, B, C#m, D#m
