My math class is stupid. We all have to give a presentation on applying math to real life. So, it's been presentations about the metric system, doing taxes, how likely an answer will come up on a magic 8 ball, and I've chose polyrhythms. I have to talk for 4-5 minutes, that general area. Plus, I can play audio examples. Other than using time signatures as "fractions"... what should I talk about? Also, what are some really simple/popular examples of polyrhythms that I could play for a class? Something somewhat repetative perhaps?
