Tchaikovsky's sleigh rhythm is a complex trilogy, allegro, four beats or four beats. Tchaikovsky's Sleigh is the first complex trilogy with a clear and beautiful melody, which shows the drivers and passengers' particularly happy mood and reflects people's infinite yearning and pursuit for a better life. Section A, a square plastic section consisting of two phrases with the same head and different endings, consists of four rows of Allegro in E major and five tones. Simple and broad, reminiscent of the driver humming Russian folk songs, driving three carriages on the vast snowfield.
