A Quatern is a sixteen line French form composed of four quatrains. It is similar to the Kyrielle and the Retourne. It has a refrain that is in a different place in each quatrain. The first line of stanza one is the second line of stanza two, third line of stanza three, and fourth line of stanza four.

Manhood belongs not to the meek.
All honor is won at a cost.
A reticent life unworthy.
All you value easily lost.
I was once unsure just like you.
Manhood belongs not to the meek.
So, stand tall when facing this world.
Cowards never find what they seek.
My hands are broken, my back is bent,
And my job is most nearly done.
Manhood belongs not to the meek.
Time to fight your battles, my son.
Those gentle eyes and chiseled chin,
Are signs that you’ll reach your own peak.
Kind men guard the common ‘good’, ‘Cuz,
Manhood belongs not to the meek.
