Try to explain why dance art and music art should be combined with each other.

Compared with music, dance is completely different in means of expression, presentation and perception. There are several reasons why dance should be combined with music:

(1) Dance is similar to music. The first is rhythm, which is the basis of their combination. Both dance and music have a sense of rhythm, and dance needs music to strengthen the sense of rhythm. The fundamental reason why primitive dance was combined with music from the beginning lies in rhythm. In a deeper sense, people's rhythmic movement naturally needs music, so all kinds of rhythmic collective labor in past dynasties have labor songs. As a free-paced expression of emotional impulse, dance naturally needs the cooperation of music. Of course, what can be combined with dance is not any music, but music with distinct rhythm. Music is easily combined with other arts, such as drama, movies, poetry and so on. But dance is the easiest and inevitable combination because they have the same rhythm. Second, lyric. Both dance and music directly express feelings, and the expression of music is abstract, which will not overlap, contradict or interfere with the specific expression of dance, but can play a role of contrast and rendering, and the two can be seamlessly combined. Thirdly, dance and music are displayed in the process of time, so that they can be combined synchronously.

(2) Dance needs the stimulation and reinforcement of music. Without music, it is difficult for dance to fully express its feelings. Music has the characteristics of direct infiltration into people's hearts, and the appreciators often experience the feelings expressed in music as their own inner feelings. Dancers certainly have a deeper feeling and understanding of the music as part of their performance. This kind of feeling and understanding further stimulates the inner feelings, which are expressed through external body movements. Music can also enhance the expressive force of dance. Music can strengthen the emotional color of dance, help reveal the content of dance, and make dance more vivid and attractive. Music can also directly touch the feelings of the audience, which is equivalent to adding an emotional bond between the dance and the audience, making 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 they are displayed at the same time, they must be highly coordinated. Dance works are not accompanied by music after the action design is completed, but there must be music before the action design. There are two ways to use dance music: one is to use ready-made music, and the other is to create music according to the theme and plot of the established dance. "Choreography according to music" is a common technique used by dance choreographers.

Of course, dance is not only influenced by music. First of all, dance should choose music, because not all music is suitable for dance. Secondly, if you create music specifically for the specific dance works under consideration, you must obey the requirements put forward by the choreographer. In addition, the choreographer can also request to modify the music during the choreography.
