Music Box Intervals

A song (the genre of the song can be rock and roll, heavy metal, pop, country, alternative rock, etc.) has intervals of music that sound like they came from a music box. These music box intervals may sound light-hearted, nostalgic, or calming compared to the rest of the song. Sometimes it can serve as a creepy contrast to the actual song, or it may actually go well with the general theme/sound of the song.
