Among them, the most important personality is Bek-seok`s poetry expresses traditional life 재강 by unique expressions and its forms. The purpose of this thesis is to research the aesthetic of the Pansori in the Bek-seok`s poetry. I would like to compare special expressing form and genre of Bek-seok`s poetry with the Pansori will make sure the characteristic of the Bek-seok`s poetry. The most unique expression of Bek-seok`s poetry is that it uses words or sentences continuously that has similar meanings and arrange them long. Bek-seok`s poetry uses repeats and arranges and these expression methods show the meanings and feeling of the poetry lively. These expression methods are very similar with the methods of Pansori. Bek-seok`s poetry continues verse and prose periodically and has a rule in telling them. These rhythm form is similar with the Pansori`s structure Pansori continues "chang" which is sang by verse, and "aniri" that is narrated by prose. Bak-seok`s poetry narrates the situation in prose and express detailed description in verse, too. Also, that prose is expressed in repeating and enumeration, jrst like Pansori. Thus, in Bak-seok`s poetry, parts that are expressed in prose is similar to Pansori`s "aniri" and the part expressed in verse is likely to Pansori`s "chang". It expresses the meaning of the poetry and feeling lively through these special rhythm systems, The Bek-suk`s poetry genre is very unique. His poetry has "epic characteristic", but he doesn`t use plot. Each scenes are expanded and each of them make a story. These unique "narrative poem" is just like Pansori style. Bek-seok`s poetry didn`t just use this special form in repeating`s and enumeration`s long literary style, but by using in narrating and describing simply, he discovered a very unique style of his poetry.
