By your own admission, this is an area where the ability to read/write music would improve your craft.quote:I only feel limited when it comes to lead guitar playing as I've never really learned scales etc so I have to find my way around by ear generally.
IMO, the speculation that Neil knows how to read/write but doesn't use it is something that could work for you as well. I guess I just don't see the downside of learning to read/write music. Obviously, you can get by without it, but it's not like it's painful to learn (again, for most people). I just don't understand why some musicians don't want to learn to read music -- particularly young ones. I can see how, as you get older, you feel you don't need it or you're set in your ways.
