The Emperor's Waltz started from the book at the beginning of the film until the owner started playing the piano, and there was a palace behind it until Tom sat down at the piano. This also shows that this is a story related to royalty.

The first song Tom played in it was the blue Danube, which is the second national anthem of Austria. It should be the song you said at 4 minutes. After Tom caught the mouse, he was praised by the servant for letting it go. After the palace, the mouse played a musical joke. The first song played was wine, women and songs, and then it was changed into chirping polka

. In fact, there should be a Viennese temperament in this film. Strauss wrote the names of the group of people who appeared at the beginning of the film during the economic crisis in Vienna in the 187 s, and when the mouse came out to dance for the first time, the soundtrack was mainly the emperor waltz and Viennese temperament.
