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

How about showing different movies etc. with different (background)music? Let the audience tell or write down what kind of mood or vibe they feel and see the difference it makes what kind of audio there is.

A few years ago a teacher at college played an audio sample taken from a movie and we had to guess what is was. Really funny, it turned out to be a fragment from a movie with a ship in a heavy storm, with things breaking and the engines roaring. No-one had guessed that when hearing it only, but with the visual it al made sense.

So you have different options to show the importance of audio and music for the way people feel and to create certain 'moods' in movies etc.
