Thanks for that, Bruce. I find it very encouraging to think that the "wall" may not be fixed, but may creep away from me if I pretend to ignore it. I'll put that to the test some time soon, but trying out some things I've got stuck on, and see if I can take the "wall" by surprise.

I think maybe in sessions it happens sometimes, when someone else leads a tune and I start to play along and then after a few lines I think, "Oh right, I remember what this is!" and then, a few bars later, "..but I can't play this one!" Only I find I seem to have played it somehow - badly, I expect, but somehow. Perhaps sometimes you just need to let your subconscious and your fingers take over, without analysing too much.
