There is an opinion that in the traditional society Pansori indicated Ba-tang sori (Korea:바탕소리, a song that includes the whole story) and if a singer sang certain parts of a story, usually famous parts, it was called just 'sori'. Today if a singer sing a full story, it is called Ba-tang sori whereas, if a singer sing just some parts of the story, the sori is called Toe-mak (Korean:토막)sori or Ma-di (Korean: 마디)sori. Toe-mak sori was mainly sung by sorikkun in the 20th century. However, after Dong-Jin Park, a famous male sorikkun, sang the full story of Heungbuga for five hours in 1968, many sorikkun tried to sing Ba-tang sori which requires sorikkun more efforts to sing.
