Park, Rok-Ju(1905～1979) was the celebrated singer of pansori which has left a clear trace centering around the history of modern pansori. This paper tried to make a contribution in building up her great position as arranging her artistic life and the world of art that has exerted a beneficial influence upon the history of modern pansori. She was a central figure of continuous pansori system from the 1930\'s to the 1970\'s. Even if she has gotten into action as a leading actress of Changguk[Korean Folk Operatic Song] from the 1930\'s to the 1970\'s, it was the legitimate pansori that she has persisted in to the last. As she has left a large amount of sound recording in the SP disk under the rule of Japanese imperialism and the LP one after liberation, we can figure out her art world. Her art world as a rare ballad singer of Tongpyonje[the Eastern School of pansori] in the middle of female master singers is as follows; First, she stores away the tradition of Tongpyonje pansori just as it is. Second, her sound is ancient and simple-hearted, but has a deep taste. Third, she tried to create the pansori toward matching her vocal sound and art view. Fourth, Hungbo-ga[Song of Hungbo] is his favorite performance, and Chebi Nojeonggi[Song of the Swallow\'s Journey], Pak-taryeong[Song of the Gourd], Pitan-taryeong[Song of the Silk], and Paekpal-ga[Song of the White Hair] which is called tan-ga[short song] among them are tonum[her singing style].
