Another new one on me, and a relatively new form. To find out the rules, have a look here at some examples as the rules aren’t hard and fast and there are several types to choose from. I had a go at two of the styles. The first two poems follow the syllable rule: five line poem on any theme with syllables following a 2-4-6-8-2 pattern.
In trills of song,
River runs ever to the sea.
Among dry sedge,
Flutter of brown songbirds,
While sorrows slide into the stream,
This third poem is based on the ‘words’ style: 1-2-3-4-1 pattern of words where the first is a noun, the second two adjectives describing the noun, three and four description, emotion, and the last word a synonym for the first noun. Sounds complicated when I tell it, but it isn’t.
Singer of songs,
Lighten our winter darkness,
For the rebels amongst you, I’ll accept any five line poem as long as it follows some kind of logical pattern.
