I listened to the midi first, and I was like
But then I looked at the lead sheet and realized it was in 7/8. Nifty. Unfortunately, I don't have my keyboard, or perfect pitch, so I don't know how well those chords gel together, but they seem pretty spicy. One thing- If you have the same chord two measure's in a row (that GM7), I don't think you need to put it in the second measure. Correct me if I'm wrong.
I guess it couldn't hurt either way.
If you could post a midi with the melody and some chords behind it, that'd be helpful.
