In my lifetime, I've learnt recorder, clarinet and a little piano, and I still can't sight-read. It's odd, because I'm a very visual learner in most ways. I used to think it was because I had such a good memory - I'd memorise the piece too quickly and then I'd just be playing it from my head using the music as a guide rather than actually playing what I saw. Since I was diagnosed 4-5 months ago with AS, I'm wondering if it's more complicated than just a memory issue. I've got a book that's supposed to help with sight-reading skills; if I can get up the discipline to actually study it properly, I'll let you know how it goes.
