History of Changjak(newly-composed) Pansori(long dramatic song) can be divided into four periods: 1) from 1930s to 1950s when effort was made for the establishment of new Pansori culture and Yeolsaga(Song of a Patriot), the first Changjak Pansori, appeared, 2) from 1960s to 1970s when Park Dong-jin, a Pansori singer, was very active, 3) from 1930s to 1990s when Im Jin-taek, a Changjak Pansori singer, played an important role, 4) period since 2000s when young Pansori singers make a variety of experiment in Pansori. Awareness of crisis in transmission of Pansori was started to occur in the early 20th century. People\'s interest in Changjak Pansori was related with this awareness of crisis in the transmission of Pansori. The Changjak Pansori that people continuously tried to make since 1930s played a certain role in expanding the horizon of Pansori, by accepting the requirement of the era. Today\'s situation where people have interest in Changjak Pansori, though not in great numbers, much more than before also ironically shows the crisis of Pansori. The great resources of Ch0angjak Pansori are the very elements of traditional Pansori such as singing method, Jangdan (rhythmic pattern), melody, etc. Therefore, the first important element to estimate the success or failure of Changjak Pansori is whether or not to practice to master the skill for using Jangdan and putting melodies properly, which is in fact a prerequisite for working on Changjak Pansori. It is never easy to sing Changjak Pansori when it also is hard to master the five traditional versions of Pansori. But, if people avoid Changjak Pansori for this reason, it is very much likely to threaten the existence of Pansori itself. The second important element to estimate the success or failure of Changjak Pansori is the existence of good text. It is because Pansori becomes a successful performance only when good literary text and artistic skill for expression are combined.
