The Kyrielle is a French four-line stanza form that has a refrain in the fourth line. Each of the lines must contain 8 syllables. The poem can be of minimum 2 stanzas or longer. The rhyme scheme in the poem could be any of aabb/ aaab/ abab and abcb.
My exampe below will help you get a better grip on the rules and structure of a Kyrielle :
You open out your palms to me
A rose of desire, burning flame
A cloud you pose to barren lands
Maybe my heart is not the same
A man so frail as cuckoo’s nest
A puzzle not so hard to tame
All of it, just a mirror now
because my heart is not the same
The hilltops have been fleeced to plains
“Oh my Lord, that is such a shame”
A plea, a song, and an exclaim
but my heart is just not the same.
