The lyrics you've posted plus the lyrics already here help put a better understanding on what the song might actually mean.
To me it seems like a story about a man who loved a girl and when she played the piano, it represented their love to him.
Some thing might have happened, perhaps just the passing of time, or her playing changed a bit, and he grew wary of their love.
Never wanting their love and the music to die, he locked her in a room with the piano to play for him alone as he stood by her.
Keeping her as a 'pet' away from everyone, people began to wonder where she was.
Eventually they found the room with her corpse still at the chair and him a) standing over her as if she was playing, or perhaps b) holding her dead fingers and playing for her.
The next part lays it out pretty well.
He then goes to jail for her murder and the police take him back to the scene of the crime where the beginning of the song takes place.
Very powerful story telling no matter the meaning though.
