Dyslexia is not that simple Ex. Some get hit harder than others. It can effect how well you can process linear information as well as spacial relationships like left and right, clockwise- counter clockwise. Pattern recognition etc.
I feel your pain, I have even more trouble than you with my dyslexia. The only thing that saved me was Kirk's
Plane Talk material. I would still be held hostage to playing tabs only if I hadn't stumbled over his stuff. It will definitely help you keep track of where you are in a tune.
