I think it would be for Snow White. The Dwarfs rush home and find her dead, and the music begins. Then they'd play the music up until the prince comes and kisses her (maybe they could add in a little montage of the dwarfs standing "eternal vigil", just to stretch the music a bit). When she wakes up it's silent, but then a bunch of happy music starts playing.
It sounded like a sad, mourning sort of song, so yeah.
