Haiku poems are more than just 17 syllables in three lines of 5-7-5 syllabication. Many styles of Japanese poetry rely on syllable count to establish poem structure, similar to the Greek iambic or "feet" (or meter) poems. Notable are the iambic pentameter poems, composed of five lines with ten syllables each. Haiku and senryu are structured on "mora" or "on" which are similar to syllables, but not an exact corellation. "On" in Haiku and Senryu is simliar to iambic feet, which are patterns of stressed and unstressed syllables. Thus haiku are cadence (rhythm) poems vs. rhyme poems, but the similarity of western poetry ends there. Use this guide to teach haiku writing or to write your own. Read on for more information...
