This song very cleverly describes what is going on musically in a very popular holiday song. Though it is a bit humorous, it does a good job of explaining the intervals and harmonic structure of the song. It also gives you an idea of how to use music theory to analyze or compose music. I especially like the musical allusion to the cartoon theme song at the end.
Thanks to David Rakowski for offering up this little treasure. I hope it gets a lot of play.
