Tomo Fujita Guitar Wisdom

Is anyone else having trouble keeping up with what is going on in Theory 07 Lydian? I understand Lydian is just #4 and I understand that A Lydian has a D# instead of D, but the rest of the lesson is going pretty fast between examples of practical uses of A Lydian.

I couldn't tell if the John Mayer style was to illustrate using a #4 chord in a progression, or using the Lydian mode to create a melody over a chord progression. For now I am going to move on remembering Lydian is #4, but please share if there's more to be gleaned from this lesson!

I've been working on the theory section, too, and so far I've learning and practicing ionian, mixolydian, lydian in C, F, G (so far) aeolian, and dorian scales in A, C, E in two octaves scales with note names, intervals and solfege in as many areas of the fretboard and I'm trying to hear the differences in quality or colour as I do them, like contrasting them with each other.

I have to admit that I too get lost with the examples at times as I think I don't know enough yet to apply them at this time. So, far I've only been able to connect the #4 with the b5 in the blues scale and am trying to add that to improv sessions but that's about it. I'm not even sure if that is correct haha.

What are you thinking of while doing lydian?
