Music is like any other language. Kids can learn it easier than adults. To a kid, learning music isn't that fundamentally different learning Italian, it's a means of expression. I started playing when I was five, started getting serious sometime around this kid's age. Things came pretty easy back then. I think almost any kid can do this, but the vast majority of kids don't do this. They just don't get as much fun out of it as he does and when a kid has fun doing something, he does a lot of it. We'd call it woodshedding. He's just having fun. But I'm sure he has practiced a lot. He just doesn't think of it as practice.
Unfortunately Adam, it probably won't go viral because it isn't crap. It's a shame that's how it is. This goes back to my theory that talent has nothing to do with fame and fame has nothing to do with talent. It's obvious everytime there's some crappy harmonica on the radio or TV and everytime Jason's phone doesn't ring.
The above has like no views. That kid has talent. This kid below is closing in on 400,000 views. Nothing wrong with the kid, but 400k views? See what I mean?
I bet he would be a blast to watch drummin to some heavy metal. He was entertaining with that tune, one can imagine where he is headin as an "entertainer"?
