What are the basic elements of a good square dance?

I think the essentials should include both individual and collective levels, for the collective need to pay attention to the choice of dance music, the choice of dance types, choreography, etc.; for individual dancers, the coordination of input and cooperation is the most important. The following content is my Baidu to, including the definition and contact method, although theoretical, but the theory is the guide to practice, I hope you can help you, so that you can be inspired by it. (The following quoted from Baidu Encyclopedia) According to art historians, the earliest art produced by mankind is dance, and square dance is the mother of dance. Square dance originates from social life, produced in the people, the masses are the creators and performers of square dance. Many people say that square dance is folk dance, which is an incorrect statement. Square dance should be divided by the form of performance, not from the type of dance. Can't modern dance and ballet be performed in square dance? Society is developing and so is the art of dancing. In the past, people defined square dance as a type of dance itself is a narrow definition. I think square dance is a form of performance, not a type of dance, but the proportion of folk dance in the square dance is relatively large. Square dance is performed in the audience, at least three actors face the audience to perform directly, the actors and the audience can communicate directly. The stage and the audience are one, and the audience and the actors mingle and become one, making the audience have a special feeling. This is the first characteristic of square dance.　　1, cheerful theme: due to the special nature of the square dance performance form, the performance site on three or four sides are the audience, the performance stage and the audience is the whole, the performance site is crowded firestorm lively. This makes most of the square dance performance content must be enthusiastic and cheerful, with the dance terminology is emotional dance. This form of performance determines that square dance is not likely to show the content of sadness or very meaningful works. This is because of the special performance environment of square dance. Therefore, the content is simple and cheerful is the second characteristic of square dance.　　Collective Dance: Square Dance is a performing art form with strong mass participation. It is performed by group dances with dozens of people or hundreds of people. The scene is red-hot and lively. Square dance must be performed in the square, the performance site is generally wider, the number of performers can not be too small. So the square dance is generally in the form of collective dance to show. Most of the performances in the wide venue do not use the solo dance, duo dance, trio dance form to perform. So the collective dance is the third characteristic of the square.　　3, due to the simple: square dance is an art form performed in the square, at the same time the square dance performance has great flexibility. The time can be long or short, completely reflecting the subjective and objective will and need. Square this performance environment can not have a very good set choreography to reflect the complexity of the performance content. So the square dance both in the performance content, dance structure can not get too complicated, only * full of emotion and changes in formation to win the audience's favorite. So because of the simplicity of the square dance is the fourth characteristic.　　4, self-entertainment: since the square dance since the emergence of self-entertainment is the main feature of the square dance. People do not want to seek fame and fortune when participating in square dance, it is totally for self-entertainment. For example, on the 15th day of the first lunar month, most of the square dances are spontaneous performances of the people during the morning exercise.　Square dance is the art of expressing emotions through dance, which allows the dancers to vent their inner emotions and produce a sense of joy that lifts the spirit. At the same time the viewer also gets spiritual enjoyment. This allows the dancers to get the opportunity to express themselves, resulting in a sense of self-worth. This is the reason why square dancing is so entertaining. This is also the reason why square dance has endured since its creation.　To summarize, square dance is a dance form that combines self-entertainment and performativity into one, with a special performance form, enthusiastic and joyful performance content, and a group dance as the main body to perform.　　The following are the suggestions in the encyclopedia for contact methods: According to the difficulty of a set of movements, the arrangement of learning a full set of movements, the sports level of the exerciser and the degree of proficiency in mastering the movements, etc., the following methods of teaching and practicing can be used.　　Section practice method: that is, each section of the action to practice separately.
