Clical music listeners/musicians, a question?

I know creepy original piano music, that is very sinister in itself. It is by Chopin, and it is used in the game The Clocktower Three. Unfortunately, i do not know the name of the song. Also, i know a German playwright song that is very sinister. It is Mitternacht, by E-Nomine, and i absolutely love it. More creepy music can be found with a group called Midnight Syndicate. Now, creepy original organ music...ah! I know. Tocatta and Fugue in D Minor. My favorite musical piece. I hope this helps, even if i could not think of a song with violins wailing. :)
