Added an audio clip

I guess I figured out how to do this "add audio" thing through a major process of trial and error. But I may have succeeded, finally. On the right is a little recording I did with Smart Music at work yesterday in about 5 mins. (Unfortuanately, the "smart" part wasn't in high gear as the computerized piano accompaniment didn't follow me too well.) If this actually worked, I'll likely add some other stuff soon. (Don't everyone groan at once, please take a number and wait in line.)
