Monorhyme
Quick answer: Monorhyme is a poem or passage in which every line ends on the same rhyme sound, an AAAA scheme. Learn its history in Arabic and Welsh verse and its uses.
Monorhyme is the use of a single rhyme sound at the end of every line in a poem or passage, a scheme you would letter AAAA. Instead of alternating or pairing sounds, the poet commits to one chime and rides it as far as the language allows. In English this quickly becomes conspicuous, since our rhyme stock is thin; in Arabic and Persian poetry, whose grammar makes rhymes abundant, monorhyme has sustained masterpieces for centuries.
The effect is incantatory. One returning sound turns a poem into a bell struck over and over, which can build obsession, comedy, prayer or hypnosis depending on what the lines are doing between the chimes. It is also a superb endurance exercise for any poet who thinks they know their rhyming dictionary.
How It Works
Every line must land on the same sound without the sentences going strange. An invented example: 'The house repeats its one grey tune of rain; / the gutters memorise it pane by pane; / I write your name and cross it out again; / the kettle sings the verse it cannot explain.' Four lines in, the ear already leans forward for the next '-ain', and the poem's obsessive mood is doing half its work through the scheme alone.
The craft problem is variety inside sameness. Since the endings cannot change, everything else must: line length, syntax, imagery, tone. Monorhyme punishes lazy lines faster than any other scheme because the repetition invites comparison.
Where You Will See It
The classical Arabic qasida holds one rhyme across dozens or even a hundred lines, and the ghazal keeps a single rhyme-and-refrain pattern through all its couplets; Hafiz and Rumi worked within such schemes in Persian. Medieval Latin hymns sometimes rhyme whole stanzas on one sound, and Welsh poetic tradition includes monorhymed stanzas in strict-metre verse.
In English the device is usually short and pointed. Dylan Thomas, raised amid Welsh sound-craft, threads long single-rhyme runs through poems like 'Author's Prologue'. Comic poets use monorhyme for escalating absurdity, each new rhyme upping the ante, and children's verse loves it for chant value.
How to Use It in Your Own Poems
Pick a rhyme sound with depth before you start: '-ay', '-ight' and '-ain' offer dozens of options, while '-orange' offers none. Suit the scheme to obsessive or circling subjects, insomnia, longing, a thought that will not leave, so the form enacts the content. Keep the poem short in English, eight to sixteen lines, unless you are deliberately testing endurance.
Slant variants can extend a run when full rhymes thin out, and the slight roughening often improves the music. If the poem starts choosing words for you, stop and cut back to the lines that earned their place.
What poets can take from this
- Audit your rhyme sound's stock before committing; count at least fifteen usable words.
- Vary line length and syntax aggressively, since the endings cannot vary.
- Match monorhyme to circling emotions: obsession, prayer, insomnia, fixation.
- Keep English monorhymes short; the scheme tires faster than ABAB.
- Allow a slant rhyme or two late in the run; the flicker of difference refreshes the ear.
Try it yourself
Choose one rhyme sound with a deep word stock and write a 12-line monorhyme poem about a thought that will not leave you alone at 3 a.m. Vary your line lengths from four syllables to fourteen so the single chime never falls in the same place twice.
Questions
What is the difference between monorhyme and a refrain?
A refrain repeats a whole line or phrase at intervals; monorhyme repeats only the end sound, on every line. A ghazal famously combines both: a repeated refrain word preceded by a monorhyme.
Why is monorhyme more common in Arabic and Persian poetry than in English?
Those languages generate rhymes far more freely through their grammatical endings, so a poet can hold one rhyme for a hundred lines without strain. English rhyme stocks are shallow, which makes long monorhyme runs difficult and conspicuous.
