From a movie- and I can't even remember the movie. What I do remember is that is that the song is played during a scene where I remember lots of softly glowing lights or patterns moving around, and I think one of the characters is dying/passing on and the main character is super sad while this classical music plays that's really slow. I'm doing my absolute best to remember, but it's definitely like a fantasy/magic involved in the movie scene. The music is meant to be kind of melodic with the scene, but its not piano and it's just like a bunch of string instruments playing. My two movies I tried scraping through soundtracks for so far we're Super 8, and John Carter. It might be an anime/cartoon though. If you all could just start tossing things out and maybe I can remember more.
