Gershwin and Improvising

Just worked on "I've Got a Crush on You" today. I probably could have finished it if I kept it as originally planned, but I added an intro to it. It's coming along nicely.

I just don't know about this improv stuff. One minute I want to use this method, then another method, then another...etc.

Part of me just wants to copy what others have done and memorize their improvs. Another part of me want to use a more method based approach.

There's a book I'm interested in. I know, I know, yet another book. But this will be the limit. One more book and then I just have to pick one method and STICK WITH IT.
