Curious about this notion of 'special talent' - So some people are just born to be better guitar players? Are you saying that something in the brain is pre-wired to be a better guitar player?
I'd say for a claim like that, you need a citation (preferably multiple).
In my opinion: You can excel at anything you like, you just have to work at it (it helps if you do it when you're really young, as your brain has higher plasticity). Get rid of this "special talent" notion.
