ummmm....what is your point again? this thread started with someone asking what mode to play over a simple chord progression, I'm pretty sure I answered that, but for some reason your talking about the idea of modalization. Important yes, from a theory point of view but entirely useless from a practical standpoint. Sure Mixolydian and Lydian Dominant are closely related from an step pattern perspective, but they are completely oposite from a melodic one. Fact is that I could play a Lydian Dominant over any minor chord and achieve varying levels of moods and atmosphere, but a C7b5 is the "best" choice for this type a scale. I guess were saying the same thing just different ways, which is cool...........not everybody learns the same way. Cheers
