If you like unusual musical instrument apps, and especially if you have kids, then you owe it to yourself to check out this really neat musical instrument app. I'm really having fun playing around with the notes and harmonies. It's kind of like a wind harp, in that you can change notes by moving your iPhone around, so you can "conduct" and play at the same time!
There's a lot of content in this app, with a wide variety of scales and keys to choose from, including the ability to set it to left-handed or right-handed use. I'm really enjoying using this unique musical instrument app!
