Slot #4 eyeball.. can't find!

[here2seetheshow]

I looked up spoilers to get the final eyeball I need ($#4), I went in to the secret room and played the middle C on the jack in the box. I looked up spoilers for the notes I should play in order, so I have those. I went to the drain, the spider isn't there and I played the notes.. nothing happens. Is there something else I need to do in order to get this last eye? Every time I ask Ned for a hint it's just about the graveyard game and I've already played that in full.

Please help!

If you already know what the notes are, then perhaps you are plucking the incorrect strings?
