The waltz that best embodies Chopin's personality and nationality, anyone will definitely say this is the waltz in C minor. This song was written in 1846- 1847. Its rhythm is similar to Mazzuca's dance music, but it is not a dance music accompanied by dancing at all, but a real waltz lyric poem. This song was written two years before Chopin's death, which symbolizes his understanding of life. Schumann once called Chopin's waltz "the waltz of the mind", which is more accurate for this song.

Music is a three-part style, and the performance is chaotic. At the beginning, it was the first main melody, with a hint of sadness (fragment 1).

It still has Chopin's gentle and elegant personality, which shows that the author still has a glimmer of hope for a better life. The second section is rapid linkage, crystal clear as a ball falling from a jade (the second section). But this is not the gorgeous style in Chopin's previous works, but full of a helpless melody, as if the author were pouring out his lonely old age. At that time, Chopin, who had lived in a foreign land for a long time and was alone, was seriously ill and helpless and depressed. The middle part was changed to D flat major, which was a little clear, but soon there was a depressing atmosphere. After the roundabout, the main melody began to repeat, and finally the whole song ended in anxiety.
