Monorhyme is a rhyme scheme in which each line has an identical rhyme. This is common in Arabic, Latin, and Welsh works, such as The Book of One Thousand and One Nights, e.g. Qasida and its derivative Kafi. Monorhyme is also used in the third verse of American rapper Jay-Z’s song Already Home.
An example of monorhyme is the poem “A Monorhyme for the Shower” by Dick Davis.
A Monorhyme for the Shower
Lifting her arms to soap her hair
Her pretty breasts respond – and there
The movement of that buoyant pair
Is like a spell to make me swear
Twenty odd years have turned to air;
Now she’s the girl I didn’t dare
Approach, ask out, much less declare
My love to, mired in young despair.
Childbearing, rows, domestic care –
All the prosaic wear and tear
That constitute the life we share –
Slip from her beautiful and bare
Bright body as, made half aware
Of my quick, surreptitious stare,
She wrings the water from her hair
And turning smiles to see me there.
