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, just play all the white notes on a piano, starting on F.
• Lydian mode consists of notes with the following intervals: T-T-T-S-T-T-S
• As an example, make sure that “E” is at the top of the circle. You can see that in order to play E lydian mode, you simply need to play a B major scale, but concentrating on the E.
• To see what notes are in an E lydian scale, first put E at the top of the circle and look at the note in the Lydian position — that is B, so E lydian is achieved by using the B major scale. Then move B to the top of the circle and you can see what notes are in E lydian, because they are the notes from the B major scale: E, F#, G#, A#, B, C#, D#.
• To play chords in E lydian, first put E at the top of the circle and look at the note in the Lydian position — that is B, so you play chords from the key of B major. Then move B to the top of the circle and you can see those chords, which are the chords for E lydian: E, F#, G#m, A#dim, B, C#m, D#m.
• Play any major scale but start on (concentrate on) the 4th note in order to achieve a lydian scale.
• E lydian is relative to (contains all the same notes as) B major (or B ionian).
