OK, I'm right back where I started, then.

Please correct me if I'm wrong, but isn't E Phrygian made up of the same notes as, say, E Dorian?

So, if I decide to solo using E Dorian vs. E Phrygian, does this not mean that I'm using the same notes anyways? How does this affect my solo? Someone mentioned something regarding the tonal center, or the note that the solo resolves to, but in the course of a solo, not each passage necessarily resolves to the same note.

BTW, if my persistence in this discussion is starting to frustrate anyone, please feel free to stop responding, and my sincere apologies!
