V aldridge is an American contemporary aesthetician. When talking about dance, he said: A good dancer is a moving statue ... The material of dance art is the dancer's moving body, and the dancer will use this material to construct something with a certain action style. This kind of thing depicts something expressively, just as a statue depicts it alone or mainly in its form. Because of this fluidity, the final form of the whole dance will contain elements of time and rhythm ... But a complete dance, although it has a sense of time extension and continuity, although its aesthetic space is more free, its comprehensive three-level form still maintains some statue-like characteristics. To say the least, it is still a plastic art … Dance is usually accompanied by music, so it is an impure art … But music enriches and strengthens the dance media, enabling it to carry image content and emotional content in a way that sculpture can't. Therefore, dance can tell stories ... Dance gives a detailed description of literature or title music in the form of dance movements, which is another impure art of dance. This impurity does not necessarily prevent dance from becoming an outstanding work of art. As long as you create and perform dance in a way that does not shift your attention from dance content to themes other than dance, the artistry of dance will not be weakened ... As long as a story is expressed as image content and emotional content in the form of dance, that is, the sculpture style and music style of dance; Then the best dancer will not object to telling stories ... Dance will never forget its most basic connection with plastic arts. This connection helps to reduce or completely abandon the narrative content of dance, and is conducive to the integration of sculpture movements and music.
