Hi,


First of all, to be honest, I know nothing from classical music, and I don't play piano.
But I heard a song I knew, but I don't know the name.
Can someone help me?

It's in this clip:

(First click on play, then there is a commercial of 18 seconds, you have to wait until that is finished).
And then in the clip it starts at minute 1:36

Thanks already!!
