[Symphonia] So I tried to play the piano

(Not sure where else this could go. I wanted to share it somehow.)

What? It's a piano....

... And there aren't enough keys to go as high as the song needs. And I know that the note I stopped on wasn't it. But I got bored and I don't know how to moosiks. :<

I have watched this a few times, but I can't tell what song it is.
