Garage band for the iPad

This is an app that you can play band instruments.  Yoy can record what you play and then make it a song.You can also hear a song as you see the notes on the instrument.  The cords on the guitar can bend.It is really cool my cousin has this app on is iPad. The app is very cool. I would like to have an iPad. I might get that app, but I am not a very big instrument person.
