Sijo is the artistic style of Neo-Confucianism view. The formal esthetics of Sijo is based on 3 chapters and 4 scores. Paradoxical duplicity of dynamic stability and stable dynamic that the dynamic poem expressed by 3 and the stable poem expressed by 4, multiple of 2, is blended is the formal feature of Sijo. The beginning and middle is the list of present fact, and the final shows the aspect that understands and realizes the general reason through the respect and self-study about the beginning and the middle. In the final, the fast change by the integration of first score`s under the standard syllable and the relaxation by the second score`s excess of standard syllable is interpreted as corresponding with the aspect of acquiring world`s self-becoming through the respect and self-study. The tendency of Sijo is largely categorized by natural intelligence and temper intelligence. However, the original form of the form`s formal esthetics and content value is commonly based on the esthetics of the respect and self-study. Also, the stable poem that expressed by the Sijo`s 4 score is understand by the serious and refined rhythm that goes to the peace of metaphysical. In the artistic achievement of Sijo, the emotional meaning and esthetic value that the passage`s rapid change which is from the present fact of the beginning and middle to the final is awakening is importantly working. Because, according to the esthetic realization of the respect and self-study that relevant to the fundamental of Sijo`s final, the prospect of the monism continuity of the phenomenon and the nature, the common and the sacred, the judgment and the insight and the physical and the metaphysical can be expressed widely. Like this, the form of Sijo that based on the Neo-Confucianism basically has the religion quality that is the historical expression of Confucianism. That is acted as the power that the Sijo genre can last about 600 years. Therefore, the present possibility of Sijo is deeply related to the culture of Confucianism life`s present value. The practical method and attitude of the Confucianism that pursue the reason by making the devout mind is the virtue of the life that is continually demanded in 21 century. As the everyday life of the modem society became varied, confused and secularized, to look straight the fundamental of the other side`s life and to internalize that in the life is more importantly demanded. The modem Sijo has bigger meaning to complete in the esthetical form and the content value of natural Sijo, not to concentrate on the formal extension and modification that is compete with the free verse. As flooding the superficial sensationalism and materialism, the esthetical form of the idealism that pursues the original life`s reason through the refined language of voluntary poor has the precious value.
