Show this powerpoint show before your performances, and you will be amazed at the difference in audience behavior. I've found that many parents just don't know how to be the best audience for their children. I usually run it on a continuous loop with soft music playing in the background while the kids and I are getting ready in the music room.
*This slideshow is fully editable, so you can use it as a starting point to make it fit your school or venue. Add in slides about upcoming events to keep your parents informed!
