Sijo (/ˈʃiːdʒoʊ/; Korean pronunciation: [ɕʰidʑo]) is a Korean poetic form that emerged in the Goryeo period, flourished during the Joseon Dynasty, and is still written today. Bucolic, metaphysical and cosmological themes are often explored. The three lines average 14-16 syllables, for a total of 44-46: theme (3, 4,4,4); elaboration (3,4,4,4); counter-theme (3,5) and completion (4,3). Sijo may be narrative or thematic and introduces a situation in line 1, development in line 2, and twist and conclusion in line 3. The first half of the final line employs a “twist”: a surprise of meaning, sound, or other device. Sijo is often more lyrical and personal than other East Asian poetic forms, and the final line can take a profound turn. Yet, “The conclusion of sijo is seldom epigrammatic or witty. A witty close to a sentence would have been foreign to the genius of stylized Korean diction in the great sijo periods. ”
