So, if you haven't seen it yet, there is an app for the iPhone called Ocarina which is the "first true musical instrument created for the iPhone."

"Both experts and beginners will be amazed by this innovative player. Ocarina is sensitive to your breath, touch and movements, making it even more versatile than the original. Unlike other musical applications, there are no pre-compiled riffs so musicians will find unlimited opportunities for self-expression. Advanced options allow you to choose between diatonic, minor and harmonic scales. Or channel your favorite video game adventurer with Smule's Zeldarian mode.

Like most Smule products, Ocarina is a social application. Tap on the globe icon and you will see and hear other Ocarina players throughout the world. The globe view will highlight the source of the music. Rate your favorite performances so that others may benefit from your judgment. Name your Ocarina if you want listeners around the world to identify your performances. With this robust application beautiful music is created, appreciated and shared."
