Sorry about the video quality, it's the best I could find. Start watching at 0:30 :)
This week I really wasn't sure what type of folk/oral knowledge I was going to post about. I was singing a song, like I usually am, and it hit me... Why not do a post on singing?! I think just about everyone sings at some point in their life, and people in history has, so I'd say that makes it a pretty substantial piece of folk knowledge.
