On this page I have 3 players to represent 3 different devices. I named them Peter, Paul, and Mary. I program these devices to sing for people all over the world. If you can get all 3 players started at the same time, this is a sample of a trio. You can pause, stop, or start each player at any time you want to see how these all work together. For a child or adult who has never sung before, singing with a device can be an amazing experience.
