I can learn a new tune from tab and then I play it about 500 times and still mess it up in some place. Or I can get a tune just right and not play it for a week and mess it up. Or I can be playing a tune I know and have been playing for some time with my buddy a fiddle player and just go blank right in the middle. Am I the only one that has these proublems? Maybe I am just to old to learn this.
