the title of a certain song?

I was just wondering if anyone knew the title and original musician of the one piano piece Dorothy plays most of the time. The really soft one that she learns from Instro? I personally think it sounds like a Chopan piece, but no way to be certain.

If anyone knows, please let me know! It would be greatly appreciated ^-^

Raindrops Prelude by Chopin.
