The music connotation of the song "Walking Tractor Ski" must first establish the relationship between melody and rhythm. There is a saying in traditional composition textbooks: "Melody is the life of a song". However, in a sense, this sentence denies the extremely important position of rhythm in songs. From the theoretical concept of modern music development, it is more convenient, easier to learn and easier to achieve the internal unity of songs by starting with rhythm. Therefore, compared with the melody, the rhythm is more specific, intuitive and primitive. It goes without saying that the ancient tribal peoples are addicted to the rhythm of "beating stones and attaching stones". Today's young people are keen on "disco dancing" or "dancing machines", and I am afraid that the rhythm is far more than the melody. Rhythm is particularly important in the hands of beginners in song writing. Only by mastering the framework concept of rhythm can we master this small and comprehensive music genre of songs.
