Thank you much for your quick response. Yes, I meant C and D Major for my examples. And thanx on using the small b.
Here is what I was trying to explain. When the chord progressions requires a bIII and bVII and the progression won't let me make a flat because ther is no flat in the progression. Some progressions work fine, ie, C Major -
I C
II D
bIII Eb
IV F
V G
VI A
bVII Bb
Other chord progressions don't allow a flat on bIII and bVII, ie, D Major.
I D
II E
bIII F (Can't flat the F so it stays a F)
IV G
V A
VI B
bVII C (Can't flat the C so it stays a C)
The book Fretboard Roadmaps, recommended to easily find bIII and bVII in a chord progression - bIII is 3 frets up from I and bVII is 2 frets down from I. Is this always correct? It seems that this rule only applies to certain chord progressions.
