I know that there are kids born with certain natural abilities who can just naturally play instruments, but I don't think that number is so great. I know for sure, though, that a bright kid who wants to, and is given the opportunity and the needed supplies and instruction, and is in a certain environment(music filled in this case), can be shocking by what and how fast he/she can learn. They're like a sponge. I think that they might just have been taught in most of the cases, and caught on quick. Of course, there are also varying degrees of innate capacity to consider.q
