I've recently started getting back into trying to revive my jazz chops. I've been trying to start off soloing over some basic standards - one of which being autumn leaves. I'm playing the song in Gm and I have a couple different real book versions. (the newer real books seem to have it in Em, but my recollection is that everyone played it in Gm at least in Kansas City) To my ear it sounds like the lead sheets may be leaving out some of the chord extensions, and I am seeking some advice from others. In particular, it sounds like the D7 in bar 6 should be a b9 or some other type of altered chord. It also sounds to me a bit like the EbMaj7 in bar 4 should have a #11. Any more experienced players have any thoughts on this? Also assuming that the D7 is a b9 what scale should I use over this? I've tried a D half-step/whole-step diminished scale, but it sounds pretty outside. Is there a different scale I should be trying? Also, as a more general question, I seem to remember that a V7 chord resolving to a minor I is generally an altered V? Is this correct? Its been awhile since I've worked on this stuff. Thanks for any input!
