This work has no background to tell. There is a magical legend that Chopin wrote such a waltz when he saw George Sander's dog chasing his tail one day while living with his lover. But this statement is sheer nonsense. This piece of music also has a name called "one minute", which actually means "one minute", which means that the playing time is about one minute. I looked at my watch. It was a minute fast. So it's basically bullshit.
Waltz is the representative of Chopin's salon sketch. Nothing special, don't think too complicated. Chopin wrote this kind of thing mainly for fun. When you play, it's just like playing. Pay attention to the melody of the left bass, especially the middle part.
