Okay, I've finally made it to the final boss, and I'm stuck. I've read the boss strategy guide on these forums, which just says about his fourth form "Copy his notes. If you do it enough times, he'll fall." (Or something similarly short.) I have tried copying his notes, but no matter how fast I do it or how slow, nothing seems to happen. The stupid balls still appear and clobber me, no matter what. I did figure out that each one has a note in it, and singing that note long enough makes the ball go away. But how am I supposed to sit still singing to one ball when two others are coming after me? There just isn't enough maneuvering room in that chamber. Anybody got any hints? It's rather frustrating to get all the way to the fourth boss form after half an hour of play and then be killed by something like this!
