When you see repeated letters or syllables in a poem, you may think it’s alliteration. But it may actually be assonance or another form of consonance instead. Keep reading to learn the difference between these three devices, as well as how poets use each for auditory effect.

Poetic Sound Devices
Alliteration, assonance, and consonance are all poetic sound devices. They use repetition to create sounds and set the mood within a poem. These sounds can be pleasing if the poet wants the reader to feel relaxed, abrasive if the reader should feel tense, or any other mood.
The difference between alliteration vs. assonance vs. consonance isn’t as tricky as it seems. Here are the definitions for each sound device:alliteration – repeated initial consonant sounds in multiple wordsassonance – repeated vowel sounds in multiple wordsconsonance – repeated consonant sounds in multiple words
You may notice that the definitions of alliteration and consonance are similar. Keep in mind that that alliteration involves the first consonant sound in multiple words, while consonance can appear anywhere in the word (typically at the end). The sound devices occur in quick succession, usually within several words in a row or in a line.

Alliteration is the easiest sound device to identify in a poem. Because it involves the first letter or blended sound in two or more words, readers can track this repetition quite easily. Some basic rebab.net of alliteration would include:Roy ran in the raging rain.I slipped slyly into the slow, slippery sled.Her brown braid brushed the bridge of her brow.“Wait,” whispered Wendy, her gaze wandering wistfully.
Here is an example of alliteration used for poetic effect. Emily Dickinson’s poem “Fame is a fickle food” uses alliteration not only in the title, but also throughout the poem:
Fame is a fickle food
Upon a shifting plate
Whose table once a
Guest but not
The second time is set.
Whose crumbs the crows inspect
And with ironic caw
Flap past it to the
Men eat of it and die.
(“Fame is a fickle food,” Dickinson)
Notice how Dickinson pairs specific words with alliteration: fame/fickle, second/set, crumbs/crows/caw, flap/farmer. But in the last line, which brings man’s death, the alliterative structure breaks down.

rebab.net of Assonance
Assonance, also known as “vowel rhyme,” can affect a poem’s mood as alliteration does. The vowels typically appear in the middle of the word. For example:Water falls across the autumn rocks.The green field gleams in the warm sunbeams.“Row more slowly,” bellowed the old, bony crone.A dismayed baby wailed nearly all day.
You may observe that the vowels are not identical from word to word. In fact, only the vowel sound is required to match in assonance, not the vowel itself. That’s how a pattern like “falls across” is still an example of assonance.
Read the first stanza of “In a Garden” by Amy Lowell for an example of calming assonance:
Gushing from the mouths of stone men
To spread at ease under the sky
In granite-lipped basins,
Where iris dabble their feet
And rustle to a passing wind,
The water fills the garden with its rushing,
In the midst of the quiet of close-clipped lawns.
(“In a Garden,” Amy Lowell)
These repeated sounds represent the different noises one might hear in a garden. Check out additional assonance poetry rebab.net to see how many ways vowels can change the sound of a poem.
rebab.net of Consonance
Consonance is similar to alliteration in that it uses the repetition of consonant sounds. In fact, alliteration is a form of consonance that occurs at the beginning of a word. Other rebab.net may find the repeated consonant sound in the middle or end of the word. Here are some rebab.net of consonance:The lock stuck quickly, so Mark called a locksmith.Laura called to tell me that Lila had fallen ill.“Ready?” growled Rory’s older brother from the river raft.Fred wondered why the road wound to a jagged end.
When combined with assonance at the end of the word, consonance results in middle or end rhyme in a poem. Here is an example of consonance in “Mother to Son” by Langston Hughes:
Well, son, I’ll tell you:
Life for me ain’t been no crystal stair.
It’s had tacks in it,
And boards torn up,
And places with no carpet on the floor—
But all the time
I’se been a-climbin’ on,
And reachin’ landin’s,
And turnin’ corners,
And sometimes goin’ in the dark
Where there ain’t been no light.
So boy, don’t you turn back.
Don’t you set down on the steps
’Cause you finds it’s kinder hard.
Don’t you fall now—
For I’se still goin’, honey,
I’se still climbin’,
And life for me ain’t been no crystal stair.

("Mother to Son," Langston Hughes)
The poem takes the reader up and down a stair of sounds. The repeated -ll and st- sounds in the beginning are repeated in the end of the poem, with hopeful -in sounds sprinkled in the middle and end. Not only does the poem make use of consonance, it uses dialect to establish the poem’s mood.
