It's easy to be a musician with this app of the day. Magic Guitar is similar to Rock Band; you hit a line of notes as the move across the screen. Unlike other music games, this on lets you bend the notes and even shake your phone to give the song a different sound. Magic Guitar's song catalog is impressive, and more free songs are added everyday. There are also extra song packs you can buy, they start at $3. Magic Guitar is free to download and is available on the iPhone.
