School Demo. Presentation?

[MonksMac]

Sometime this week I have to do a demonstration speech. My topic is How Music has Changed. Everything is written up and good to go speech wise, but I don't know for sure what to bring for the demonstration part of it. Does anybody have any Ideas?
Thanks!

What sort of changes are you talking about? The changes in music itself? Or the technology related to music?

If it's the latter, then that's easy. Demo an iPod and explain how it holds thousands of CDs in that tiny little thing
