Classical music featured in introduction of Haunted Manor: Lord of Mirrors Game?

[JoyAndIceCream]

I was playing Haunted Manor: Lord of Mirrors (out of sheer boredom)]

and a piece of classical music was featured in the introduction that I recognise but could not remember what it was.

If anyone has played this game, do you know?

Its just a truly moving piece of music but I can't recall what its called.
