We tried this form back in 2009, so it's time to dig it out and try again! The hay(na)ku and was created in 2003 by poet Eileen Tabios. Here are the guidelines.
Hay(na)ku is a 3-line poem of six words with one word in the first line, two words in the second, and three in the third. There are no other rules and no restrictions on number of syllables or rhyme.
Need some examples? You can find some Hay(na)ku poetry contest winners at the Hay(na)ku Poetry blog. There is also a thoughtful essay about the form at Dragoncave. As you'll see from the examples, some folks create poems comprised of several hay(na)ku strung together.
So, what kind of hay(na)ku will you write? Leave me a note about your poem and I'll share the results here later this week.
