Prior to the jazz course I did an Edinburgh Uni course on the fundamentals of music theory, a course I recommended to Steve Gardham I think. That covered modes in a different manner the C Ionian, D Dorian manner. I passed with over 90%. So to whoever it was who thought I didn't have much grasp of modes, I found you patronising. Checked and it was Steve Shaw. Get your coat, Steve :)

True I am not au fait with the stuff critiquing the whole concept or with the various historical views of modes, but what I do know is adequate for this thread, even if not always perfectly applied.
