Musically Gifted?

Lately Vanessa has been humming a song from watching the Baby Einstein series. I'm not sure if it's a Mozart or Beethoven piece (same piece in the episode of Tom & Jerry where they convert the kitchen into an ice skating rink). It's really cute when she does it though. Yesterday she's even added her own version by using "Momma," "Dadda," or both in humming it. So it would go something like:

"Mom-ma Mom-ma,
Dad-da Dad-da..."

It's hard to convey the way it sounds by typing it out but I can totally replay her version in my head. I definitely got to try to get it on video.
