My jazz teacher has been getting me on soloing for the past few sessions. Today, I almost made it through a chorus of "Take the A Train" without too many clams, but I'm still very uncomfortable doing it. One of the things that really freaks me out is that my teacher wants me to spend a lot of time in the upper register, because the notes come out more cleanly up there. I realize that everything's the same past the twelfth fret, but it just doesn't feel right; compound this with the fact that I've always been of the opinion that the "money notes" are below the 12th fret, and you'll begin to understand this particular problem. Jazzers, how did you get around this problem? I'm really having a difficult time learning to solo in the first place--all the more irritating because I have a really extensive scalar vocabulary for a guy who's mainly played rock since he's started--and this is practically driving me to tears.
