Have you ever heard a piano piece called moonlight? When I first heard it, I fell in love with it. This piano piece is rich in emotion. This piano piece was composed by Beethoven. Beethoven was a world-famous musician and composer. He was a German. I heard his name when I was very young, which shows how famous he is. Because I do not know the source of this piece of music, so the Internet to find out, the original piano piece is Beethoven for his lover to create, this is really very enviable! But later, Beethoven because of this relationship has paid a lot of price, which is very unfortunate.
