What is that one classical piece of music?

It goes dooo do do do dooo do do do do do do do do do do do dooo dooo. It's on the tip of my tongue. I know it's used in games as I used to play a game with it in it when it was nighttime (game was similar to Minecraft). The instrumentals go up and down and it kind of sounds like it's from the nutcracker but it isn't waltz of the sugar plum fairy
