Does this indicate that, when you count backwards to grab a ‘tone-Pitch’, below ‘Tonic, you enter into a different ( flat ) key?
C, Db, Eb, F, G, Ab, Bb,-C- D, E, F, G, A, B, C.
8/1,2,3,4,5,6,7, ’1′, 2,3,4,5,6,7,8/1
Hi again Donn.
I struggle to answer you with a valid answer because I still can’t quite figure out your way of thinking. Somehow, somewhere, you’ve got this mixed up, but I can’t figure out what it is.
Here’s where I’m confused. You are trying to find the parent major scale but I think you might be counting the same thing twice, if I understand you correctly.
Let’s look at the first part of you question, “going from C Ionian to Dorian” Do you mean going to “C” dorian, or “D” dorian?
If “D” then you already know the PMS, it’s C Ionian (C major)
If you mean C Dorian, then you’ve already figured out the answer, it’s Bb major / Ionian.
For some reason you are jumping from key to key and I can’t work out why you are doing so, or thinking that you should need to.
Your question suggests changing keys. I need to figure out why you are wanting to. Have you got a particular chord progression that you are trying to work out the key of?
Each of the modes and major scales have independent tonal / key centres. It seems to me that you are trying to combine them somehow when they don’t need to be. Unless a piece of music has key changes then you have no need to relate the different modes and scales to each other.
We need to get to the bottom of this confusion 🙂
