Greg Stephens,old son.
I shall refer to tutor books I have in my possession,How to play Folk Fiddle by Geoff Bowen ,and DADGAD Guitar Book bySarah Mcquaid,both these tutors refer specifically to tunes as being in Dorian,Aeolian, Mixolydian.,or major.
I am not out Of kilter with the rest ofthe world,But in agreement with people that know their subject.
If you wish to believe that all three of us are wrong,that is your problem.Dick Miles
