Ideas for 20 minute presentation anyone

[tomii]

hi i need to do a 20 minute presentation on any theme related to music.

The presentation is graded completely on audience involvement.

Ive been thinking of themes like The importance of communication-- then I would give a presentation that would involve the audience on the importance of communication.

The most obvious approach I could take is playing music for the audience and to have them be judges, but that wouldn't cover much of a theme, and I doubt it would last the full 20 minutes. Plus I only have 5 days to prepare and I dont have an idea yet.

Ive also thought about letting the audience play certain roles they could be musicians themselves and i would somehow incorporate that idea into my presentation. They could be recording companies, critics, a crowd at a concert... but I just cant think of how to present any main theme regarding music with the audience actively participating.

thnx
