Beautifully simple design by a highly respected app-developer. This one is actually REALLY easy to use (even babies just tapping randomly on the screen will produce delightful results) but also interesting enough to engage adults (depending on where you tap the screen, the pitches may be higher or lower, so you can work on playing a scale or even a song if you want to!). The balls also roll to one side of the screen or the other if you tip the iPad creating a cascade of sounds as all the balls make their noise together. Try holding your finger on a ball for a surprise!
