What's the song on the jc penny commercial with the girl running around and trying to hide her crush on a boy?

i know. another question about a jc penny commercial. i've seen questions concerning the morales of the children in the commmercial, and questions concerning the song in nearly every other jc penny commercial. but what's the clical music they used in this instance. my grandmother used to have a music box that played this song when wound up, and i would love it if i could discover the title of the song. it's probably something old, right? bach, or chopin, or beethoven. i dunno. i really appreciate it.
