If you’d like to become a dancer, spend some time choosing a dance style. Each type of dance is made up of techniques which need to be practiced and mastered.   
Once you have decided to become a dancer, it is important to carefully choose a dance class. 
It is easy to form bad habits in the beginning, and extremely hard to correct them. So choosing a good teacher will help you a lot from the beginning.
  Special dance shoes will be required for most dance styles, including ballet slippers for ballet and tap shoes for tap. Your dance teacher will probably have a preference for clothing, such as a black leotard(紧身衣) with pink tights for a ballet dancer, or black dance pants(短裤) for a jazz dancer.
If you are enrolled in your very first dance class, tour the dance studio before your first day.         
The floors of dance studios should be soft, as dancing on hard floors may cause injuries. The class structures will vary for the different dance styles.
