Pansori is a professional art which requires sorikkun to have a high level of singing skill. Also, it is a performing art because one singer takes roles of various characters in a story. Music, literature, and play are the key elements that coexist in pansori. It was established as an independent performing art by associating with many adjacent genres of Korean traditional music such as Minyo, Mooga(songs that shamans sing in a performance of exorcism), Sijo, Japga(a folk music sung by common people during the latter part of Joseon dynasty), and Gasa. It is also the only genre that started with popular arts and led to ethnic arts in Korea.
