Finding Royalty Free Music is a great tool to add that finishing touch to a presentation. This site is a great tool to find royalty free music. The hardest part of the site is to find the piece of music that will suit the presentation.
I have found a piece of music that would suit a presentation that is fun and actively involves student participation. Called “Future Cha Cha”, the piece is fun and up beat. I would use it as an introduction or a break piece in a presentation.
