Pansori is defined as a Korean traditional narrative song that one sorikkun(Korean: 소리꾼), a singer, weaves a story with chang(song), aniri(descriptive speech), and nurumsae(motion). The name of the song is also known as gapga, bonsaga, changga in Chinese, but it has been called pansori in Korean. The term pansori first appeared in 'Mae-il Shin bo' (the name of the newspaper in 1910s in Korea) in 1913. Pansori is a performing art which one sorikkun, and one gosu (a drummer playing a barrel drum called buk (Korean: 북)) sing a song of a long story to the audience. 'Pan' in pansori means 'a place where many people gather', and 'sori' means 'sound'. Pansori represents voluntariness and impromptu which are the characteristics of Korean traditional music. For example, before Heung-rok Song period it had been orally narrated without any exact scripts by extemporarily inserting songs handed down orally and witty remarks into the stories taught by a master.
