Sanjo dance is a dance that was created with the origin of Sanjo music. Sanjo Dance was performed firstly in 1942 by Choi Seung-hee. From the 1950s to the 1970s Sinmuyoung (新舞踊, New Dance) dancers had presented the Sanjo dances. In the 1980s and around, the Sanjo dance did not draw much attention from the entire dance industry. From the 1990s to the present, the first Sanjo Dance was re-examined, and dancers newly presented various Sanjo dances. To summarize the aspects of Sanjo dance, first the Sinmuyoung dancers began to create it, and a number of the new dance-style Sanjo dances were created. In the 2000s, it has also been made in the traditional dance field. Second, after using Gayageum Sanjo by dancers, the musical instruments became more diversified, including the iron gayageum, geomungo, and haegeum, and the Sinawi format was also tried. Third, the Sanjo dance has various sub-titles, which reflect a certain motif or sense of subject matter of creation. However, Sanjo dances in the context of traditional dance tend to form a dance in the composition and flow of Sanjo music. Fourth, you can see creativity, improvisation and diversity in Sanjo dance. Creativity and improvisation are characteristics of Sanjo music, which gave rise to the diversity of Sanjo dance. The Sanjo dances developed in this flow can be divided into three contexts. These are the Sinmuyoung style, the traditional dance style, the mix of Sinmuyoung and traditional dance style.
