Below is a link to a simple mood picker I created for my final performance of the year. I did this so that my performance would be more interactive and so that the audience could get involved. We are essentially their guinea pigs. Whenever somebody clicks a new mood we will change our playing to fit that mood. I will have this mood picker on a laptop and then have it put up on the projector so we (the musicians) can see it. It is easy to use and hopefully it will be effective.
