Ocarina is an app that will turn your iPhone into a musical instrument. You set your music mode, blow into the microphone and there you are creating music. You can hold down combination of holes, tilt your phone to change vibration and depth, and change keys and modes as well.
Pretty smart? Hell yeah I wanna try it. But they didn’t forget to add the community part to it. Through this app, you can also listen to other people’s music around the world, and share yours as well.
