Music relies on the movement of music to express people's thoughts and feelings, and dance relies on changes in people's bodies to express people's thoughts and feelings. They are both good at lyricism and poor at narrative. Music and dance are both "arts of time", and both have certain intensity and rhythm. The beautiful music melody can make the dance movements more rhythmic, and the rhythm of dance can also express the beautiful music melody. This "uniqueness" of dance and music provides a solid foundation for their combination. As far as dance is concerned, when accompanied by music, it will appear more graceful and moving, increasing the expressiveness and appeal of dance. We can also understand the close relationship between dance and music from the differences between dance and music: dance affects people's vision and is a "silent" art; music affects people's hearing and is an "invisible" art. This personality difference requires the combination of dance and music. Don’t people often think that the characters in dance are “silent” and the meaning of their movements is not clear? As it happens, music can make up for the shortcomings of dance: it can "give voice" to dance. With music, the audience's visual and auditory pleasure can be increased at the same time, and the aesthetic conception of dance is easier for the audience to understand and grasp. Therefore, people say: "Music is the soul of dance."
