do you think its possible?

I had a great idea today what if you could put a mic infront of a guitar amp and the game would pick up the pitch and play it. The fretboard on the game would have to be changed to show what strings and cords to be hit but is it possible. or put a plug that will plug into the Xbox or PS3 and will play and hit notes when you play it on real guitar.

of corse a game like this would be alot harder
