Deceptive ii V Prog

[LDL]

The first thing that comes to mind is the bridge to Rodgers and Hart's "My Heart Stood Still" as in Chuck Sher's Standards book. The progression is F- Bb7 G7(b9 #5) Cmaj7. The Bb dominant and the G7 dominant share the same diminished scale. So the guide tone tritone interval B-F can be shared. You can add a Ab as well as a common tone.

I guess you would call this a pivot modulation - the upper structure Ab-B-F stays static - the bass changes to establish the new tonal center.

Thanks for the nice chord shift concept! I always like a new way to find my way to the alt V dom. But in this case the V does go to the I, which itself is an expected progression.

The difference in my progression is that the G7b9 dominant goes not down a perfect 5th (or up a perfect 4th) to the C...

...it goes down a major 3rd (or up a minor 6th) to Ebmaj7.
