This postmodern era that we live in has its characteristics of eradicating the boundaries between forms of art. In this movement, where pure art and popular art are actively fusing and the importance of popular dance is becoming apparent, this paper has been developed to study a representative case on popular dance. For research methods, case studies and Dance Analysis has been combined. Case studies on idol related publications and thesis papers were used to demonstrate concepts and characteristics of popular art and idols. With Dance Analysis, details of has been examined. To accomplish this task, details from news articles, pictures, music videos, and stage clips has been reviewed and the four stages of Dance Analysis, describing the Components of the Dance, Discerning the Form of the Dance, Interpreting the Dance, and Evaluating the Dance has been applied. The three following conclusions can be drawn from this study: First, the dance emphasizes cuteness and sexiness to attract male fans. Second, the dance moves are highly repetitive, which makes it easy to pick up, appealing to the mass, exciting and enjoyable with popularity. Third, the easy-to-follow moves are friendly and makes the spectators join to develop an extraordinary feeling of group cohesiveness. In this culture, popular art has significant influence on people. I earnestly hope that this work could offer a complimentary vision for popular dance to rediscover its true meaning and value and elevate its status to a inspiring dance.
