The beauty of ballroom dancing is mainly manifested in three aspects: First, the beauty of sports. Dance mainly expresses meaning and interprets connotation through body language and expressions. Therefore, dancers' gestures, expressions and feelings all show certain artistic accomplishment and cultural connotation. For example, the practice of standardizing movements, the control of movement intensity, the grasp of music rhythm, the limitation of advance and retreat speed, and the understanding of music melody can all be fully reflected in shaking hands, stretching arms, holding waist, shoulders, kicking, jumping, spinning, pulling, sliding, kicking, twisting, sideways, flying and hanging wrists. The second is the beauty of harmony. Both men and women constitute the overall beauty of ballroom dancing, focusing on the effect of collocation and cooperation. If there is a big contrast between the two sides, it will be a very embarrassing experience for either side. Harmony mainly refers to the coordination of dance skills, the beauty of dance posture, the lightness of dance steps and the expression of dance sense. It needs the enhancement and improvement of personal quality, and also depends on the running-in and adaptation of both sides in dance practice. The third is the beauty of tacit understanding. Tacit understanding means that both sides have the same understanding of each other, without clearly saying what they mean. The tacit understanding in ballroom dancing should be the perfection of the highest realm, which is difficult for non-professional dancers to achieve. Mainly manifested in artistic sentiment and tacit emotional appeal. One side's eyes, a smile, a hint, a gesture, the other side immediately got the message and gave positive feedback and response. At this time, both dancers are the embodiment of dance beauty. In a word, if the beauty of achieving sports is the door of dance art, then the beauty of harmony and tacit understanding is the passport of dance art.
