Your difficulties with reading music got me thinking about braille music. There was an individual who was very avid that I learn braille music. Thought it would open up such a new world for me. Well, I learned it, and hated it. I could learn by ear so much faster. The thing with braille music is that it all has to be memorized anyway, unless I could learn to read with my toes or tongue. That was infinitely more challenge than I wanted to undertake, and braille music was discarded.
In college I'd learn all my music by ear from CD or whatever. At private lessons then the professor and I would work out anything I'd misheard.
