There's a piece of music I heard while watching Ghost Story (1981). It was also in a TV movie with Alan Arkin called Necessary Parties. The review for the latter said it was Corelli. I played the basic idea of the melody on an online piano (I don't know how to play a real one, and hitting notes in time isn't that easy with a mouse and pointer, so the timing goes wrong). Any ideas? Should be pretty famous.
