There are apps for the iPhone you never knew you needed until they emerge out the murky developer darkness. Smule's Ocarina app is one of those apps.

For 99¢ you can turn your iPhone into the musical instrument of the ancients. The Ocarina app is played by blowing into the microphone at the bottom of the iPhone. The app includes the ability to listen to others playing the app with a pretty slick image of the Earth and music emanating from it.

Smule has a tutorial for beginners, too bad I didn't bother to check it out. Check out my first horrible try at the Ocarina then check out what a real master of the app can do.
