Very cool app. Let's check it out.

Some iOS Music Game and Instrument References

Here are some music games and Apps that I find interesting:

Smule Auto Rap:

Interesting app that reads voice input and turns it into auto-tuned rap like songs. 

Smule Magic Piano:

A really fun way to "play" piano in a sort of music game.  Nice simple art style.  Also has a freestyle piano playing feature.

A kind of collection of all of smule's music performing apps.

Ok last smule one, I promise!!

Smule Magic Guitar:

A magic-piano-like app.   

Ok now on to the iOS games:

Flea Symphony:

Interesting art style and game concept.  Mostly rhythm focused, and not super musical in the end.  

Groove Coaster:

Pretty addictive and fun game by the people that brought you space invaders.  Simple but effective visual style, and game mechanic of just tapping the screen anywhere. 

Tap Tap Franchise:

Rock Band-like game play, but it utilizes the accelerometer and swiping gestures.  Again, like the previous examples, you're not really creating music, just playing it back.  

Theatrhythm Final Fantasy:

Another iOS game themed to the Final Fantasy franchise.  Nice art style, simple game play.  Creative level up and character choosing RPG dynamics.
