The purpose of this paper is to investigate phonological characteristics in Yongcheol Park’s poems on the basis of syllable structure. That is, I divide the syllables of poem into onset, nuclear, and coda, then observe which phonemes are used frequently. The study of Yongcheol Park’s works sufficiently obtains a substantial argument in view of the literary theory. However, it is insufficient for the linguistic method. Poetry is based upon the relationship of similarity among sounds. Sounds perceived as similar to one another create acceptable rhythm pairs. Because sounds are hierarchically arranged in languages, patterns in poetry can reveal the priority order within this hierarchy. So, with respect to the phonological patterns of Korean, I have analyzed all of Yongcheol Park’s works. At last I found the priority order of Yongcheol Park’s poems within sound hierarchy. Most common are syllables with no onset and no coda pairs. With respect to acoustic features, the most frequent syllable utilize the [+sonorant] feature. This pattern remains consistent over time.
