This month Kat Myrman is writing a Cinqku a day. I read her first two on loved them so I am going to try one now.
“A cinqku must always have 5 lines and a perfect seventeen-syllable count. The lines typically follow a 2,3,4,6,2 format. There is no title requirement on the second line. As for syntax and diction styles, it follows the free Tanka style originally. There are no metric requirements for a cinqku poem. Additionally, the final line must contain a cinquain or kireji turn for emphasis.
Leaves fall
Days grow short
Food is gathered
The nights grow longer
Ready for renewal
Harvest.
