For a Lydian sound on Cmaj7, think:
- C major pentatonic
- G major pentatonic
- D major pentatonic
Together, these shapes reveal the sound of C Lydian:
C, D, E, F#, G, A, B
Root pentatonic
C major pentatonic:
C, D, E, G, A
This is the most stable color.
Fifth pentatonic
G major pentatonic:
G, A, B, D, E
This brings out:
- 5
- 6
- 7
- 9
- 3
Second pentatonic
D major pentatonic:
D, E, F#, A, B
This is the one that clearly reveals the #11.
Put the three together
One practical routine
- Loop Cmaj7.
- Play one bar of C pentatonic.
- Play one bar of G pentatonic.
- Play one bar of D pentatonic.
- Listen for the moment the #11 appears.
One thing to listen for
If the line sounds like plain major, bring out the D pentatonic more clearly. That is usually the fastest way to reveal the Lydian color.
