Compared with music, dance is completely different in terms of expression methods, display methods, perception methods, etc. The reason why dance should be combined with music is mainly for the following reasons: < /p>

(1) There are many similarities between dance and music. The first is rhythm, which is the basis for their union. Both dance and music have rhythm, and dance needs music to enhance the sense of rhythm. The fundamental reason why primitive dance was integrated with music in the first place is rhythm. From a deeper sense, people's rhythmic movements naturally require music to cooperate, so various rhythmic collective labors in the past dynasties have labor chants. Dance, as a free-rhythm expression of emotional impulse, naturally requires the cooperation of music. Of course, what can be combined with dance is not any music, but music with a distinctive rhythm. Music is inherently easy to combine with other arts, such as drama, film, poetry, etc., but the easiest and most inevitable combination is dance, and the reason is that they have the same rhythm. Second is lyricism. Both dance and music directly express emotions, and the expression of music is abstract. It will not overlap, contradict or interfere with the specific expression of dance, and can serve as foil and rendering. The two can be combined seamlessly. Again, both dance and music are shown in a time process so that they can be synchronized and combined together.

(2)Dance needs the stimulation and strengthening of music. Without music, it is difficult for dance to fully express emotions. Music has the characteristic of directly penetrating into people's hearts. Appreciators often experience the emotions expressed in music as their own inner emotions. Dancers certainly have a deeper feeling and understanding of the music that is part of the piece they perform. This feeling and understanding further stimulates inner feelings, which are expressed through external physical movements. Music can also enhance the expressiveness of dance. Music can enhance the emotional color of dance, help reveal the content of dance, and make dance appear more vivid and charming. Also because music can directly touch the emotions of the audience, this is equivalent to adding an emotional bond between the dance and the audience, bringing the audience closer to the dance.

(3) Dance creation should be based on music. Because dance and music have the same rhythm, rhythm, and emotional content, and are displayed simultaneously, they must be highly coordinated. Dance works are not designed after the movements are designed and then paired with music; there must be music before the movements are designed. There are two ways to adopt dance music: one is to use ready-made music, and the other is to create music for the established dance theme and plot. "Create a dance to the music," is a common practice among dance choreographers.

Of course, dancing is not just about obeying music. First of all, dance requires choosing music, because not all music is suitable for dance. Secondly, if you are composing music specifically for a specific dance piece in mind, you must obey the requirements set by the choreographer. In addition, the choreographer can also request changes to the music during the choreography process.
