True. I specifically wanted a whole tone type sound in the accompanying chord. I wanted a natural 9 and no natural 6 or 5 - just the #11, #5, b7.
Did your melody over the 7+5 chords include other tones from the AA scale?
Notation would be better, but the notes were:
8th note pickups: Ab Bb Gb | [Bb7+5 9 +11] E C D Bb | [D7+5 9 +11] Ab |
with the 2nd and 3rd notes and 6th and 7th notes being a leap up of a +5.

Simply because a "regular" D7 is a CII, so I kept it in the II category.
Modal Genre II (MG II) is a Primary Modal Genre (PMG) for a 7 chord and MG +V is a PMG for a 7+V chord, but MG I would be an Alternate MG (AMG) for this chord. So I guess in a sense MG II is a more fundamental choice than MG I.
I guess that begs the question why I didn't call the first chord Ab AA II. I guess because I viewed the Bb chord's modal genre as being I, kind of as a tonic chord to the tune.
