CarolC - ignore the guest; it's just another one of Creator's mistakes. I'm not clear on what you mean when you say you can't "hear" or "see" in your head. If you play music, I presume that you are not deaf and blind. There are many blind musicians, both contemporary and historical, but I don't know if there are any or many deaf musicians. I have heard of deaf persons who "play" by feeling vibrations. Makes sense to me.

I suspect what you mean is that you don't sense the ability to "visualize" music in your head (both "seeing" the dots in some form and "hearing" the melody or harmonies). Have you never heard a song or tune that you just couldn't get out of your head? I don't know what to say. Maybe it's a subconsciously learned skill and you just need to to practice trying to do it. Good luck, and keep playing anyway.
