I kept listening to albums where I'd hear this very joyful sound - and it was always the glockenspiel. Then I ordered one online, and I figured out how to play it.
I kept listening, kept going to see people, kept sitting in with people, kept listening to records. If I wanted to learn somebody's stuff, like with Clapton, when I wanted to learn how he was getting some of his sounds - which were real neat - I learned how to make the sounds with my mouth and then copied that with my guitar.
