I was pointed out to me by my brother that playing the guitar is a lot like playing a video game: There are certain things you need to do with your fingers at certain times, and you need to memorize the moves (either specifically or generally) before you try it so it works out better.
Here he is, at 1:10 he demonstrates the range of the ukulele. And he's at TED. Most of you have not been invited to TED. TED? Very cool. TED = ukulele.
