Well, wouldn't it be awsome if you could play that? And yes theres a method to my maddness. Okay heres how it works. The little 'piano' will be sitting there, the seat empty. The player walks up to it and enters it like a viechle. Then he's seated in it's center, his crosshairs still there. Now when he presses the fire button it has a little 'firing' animation of the players hand moving as if pressing a key. This allso launches a little invisible, harmless bullet. Each key of the 'piano' has a specific sound it makes when hit by a bullet (just like every other texture does). So basically the player just clicks on each key and the note will play! I suggest having a simple set of notes in easy reach so players can try out playing. But if the person just can't play well and longs for some good music he can click on a special key thats maybe colored a differnt color, to play a star wars song. Maybe teh 'viechle' could also have a 'secondary weapon' that works the same way as the hand moving one except this one does a longer version so it looks like the player is actually playing the recorded song. 
I'm proud of myself!
