SIJO (from Shadow Poetry Handbook)
A short Korean poetry form consisting of three lines,
each line having a total of 14-16 syllables in four groups
ranging from 2 to 7 (but usually 3 or 4) syllables, with a natural pause at the end of the second group and a major pause after the fourth group.
The third line often introduces a resolution, a touch of humor, or a turn of thought.
Nature is often the subject matter of these poems like traditional haiku.”
Either narrative or thematic,
this lyric verse introduces a truth (perhaps a problem) in line 1,
development (called a turn) in line 2,
and a strong conclusion beginning with a surprise (a twist) in line 3,
which resolves tensions or questions raised by the other lines
and provides a memorable ending.
