Funky, Bouncy Lick
Well there is nothing Lydian about the jam track or the lick. It's E Mixolydian.
If it had been E Lydian Dominant, it would have had an A# in there. Had it been A Lydian, it would have had a D# in there.
I recommend viewing this as E Mixolydian instead of A Major, because the key center is E, not A.
I'm here to help.
Funny you should mention more lessons on this concept. I understand the key center as the identity and would play the jam that way, but sometimes I need to see the scale from a different vantage point so that I don't get too myopic about the Root. BUT, I am not sure if anybody else at MGA is reading this and scratching their heads, and hopefully not thinking "that Clayton's a fool." 😦
Does anybody else here want more info on this 2 minute lesson or the concept from the Master?
