If you have an iphone, you’ll want to check these two applications from Smule. Ocarina and Leaf Trombone. Genius, What a great idea. You can play your iPhone like it was an instrument. Ocarina is flute-like or sounds like a recorder. You make sounds by gently blowing on the microphone and manipulating “keys” on the touch screen. It’s addicting. And now they just released Leaf Trombone which sounds like a trombone and offers a sliding leaf like the slide on the trombone. They also have musical backgrounds and the ability to play together with other iphone users. This is pretty cool. Kudos to Smule. Job well done!
