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

Considering that the ‘Bb, is a ‘whole-tone’ down from ‘Tonic, could it be the ‘Leading’ tone, or / Dorian – B-minor’7(b5)? / half-diminished?

I guess, I’m trying figure out the function of knowing the ‘Parent Major Scale. Going from C Ionian, to Dorian, ( the second degree counting back from C is a whole tone, Bb ), now what?
Do I play Bb Dorian? or do I find D and play Bb Major, while remaining in a compatible sounding key?
Write your answer.
Donn, you know how to make my brain hurt 🙂
I don’t think you’d call it a leading tone unless it’s a semitone. I’m not 100% certain, but fairly sure. It’s the reason the 7th degree is raised half step in the natural minor scale to create the harmonic minor so that the cadence is stronger.
The “Dorian . Bbm7b5 ” bit I don’t understand. This chord would not be in the key of Bb? Can you clarify a bit more?
