Main Body

Chapter Six: Acoustics

Even before you were born, in your watery womb home, your body recognized patterns of sound. It began with the beat of your mother’s heart, the swishing of her blood. Rhythm is primal. It is comforting, and it can be startling. When rhythms break, they wake us. When rhythms extend, we become entranced. Rhythm is integral to poetry and a mark of what poetry actually is. In learning to interpret poetry’s structures and sound patterns, in free verse, our ears attune finely to tone, cadence, pitch, rhythm, and silence. In formal verse, we employ a particular language to help us talk about rhythm.

Meter: Length and Rhythm

In metrical verse, lines can be divided into length and rhythm which we refer to as feet, and each foot’s syllable into a stress. Each foot contains either two or three syllables (see below). You may have seen the symbols used to indicate this: ˘ ΄ :the curve marks an unstressed foot, the slash a stress. In the following words, the first syllable is stressed and the second is not: Tennis. Fiction. Music. In the following words, the first syllable is unstressed and the second is: Unlock. Tonight. Against. Using this method of dividing a poem’s lines into feet and stresses is called scansion.

If we put these terms together, we can begin to scan lines:

Iambic tetrameter:

Whose woods │these are │I think │I know

His house │is in │the vil│lage* though

(Robert Frost from “Stopping By Woods on a Snowy Evening”)

*Note that feet can break in the middle of words.

Iambic pentameter:

The world │is too │much with │us late │and soon

(William Wordsworth from “The World Is Too Much with Us”)

Trochaic Octometer:

Once up│on a │midnight │dreary, │while I │pondered,│weak and │weary,

Over │many │quaint and │curious│ volume│ of for│gotten │lore—

(Edgar Allan Poe from “The Raven”)

Scansion contains many words that allow us to speak in a specific way about verse. When a line of poetry adheres to a pattern the poem has undertaken, it is called pure. But often poems are what we call impure. These poems break from the pattern—not to switch to a different meter, which can happen as the examples above show—but to alter the pattern altogether.

Impure Dactylic dimeter:

Hickory │dickory │dock

Iambic trimeter:

The mouse │ ran up │the clock

In the above example, the first line is impure. Here is another example of an impure rhythm, but one that follows another named pattern: catalectic:

Trochaic tetrameter:

Tyger! │Tyger! │Burning │bright

In the │forests │of the │night

(William Blake from “The Tyger”)

These lines by Blake are catalectic because the final foot is cut off. It also contains lines that end with a stressed beat in what we refer to as a masculine beat. If the last beat were unstressed, we’d refer to it as feminine.

The art of scansion is both scientific and subjective. The specialty language allows us to examine poetry in a calculated way, but there are times when the degree of stresses sound different to different ears.

There are many good sources on scansion and I want here to simply provide the basic language you may use to speak about poems, and to understand the detailed rhythms of your own poems. Scansion can be useful in discovering where language goes slack by identifying words that produce less energy like prepositions. It can also allow you to identify places in poems that move you, allow you to hear what patterns you are drawn to as a reader and writer.

Music and Rhyme

In addition to line length and rhythm, we also categorize lines by rhyme, especially in formal verse where an extended pattern is maintained. You, of course, have been rhyming from an early age. Children’s books written by writers like Shel Silverstein and Dr. Seuss have delighted both children and adults with their rhyming stories. Rhyme makes language memorable and pleasurable.

In both formal verse and free verse, rhyming is elemental. In formal poetry it occurs more frequently as end-rhyme, when two or more words that end lines rhyme. In free verse, the rhyme is more likely to be internal, not necessarily occurring at the end of lines.

Let’s take a look at an excerpt from William Wordsworth’s poem “The Daffodils”:

I wandered lonely as a cloud
That floats on high o’er vales and hills,
When all at once I saw a crowd,
A host, of golden daffodils;
Beside the lake, beneath the trees,
Fluttering and dancing in the breeze.

Here we can see the first and third lines rhyme; the second, fourth and sixth; the fifth and sixth. There is definite rhyme scheme. When we refer to the rhymes in this stanza, we diagram the rhymes with matching letters like this: ABABCC.

I wandered lonely as a cloud (A)
That floats on high o’er vales and hills, (B)
When all at once I saw a crowd, (A)
A host, of golden daffodils; (B)
Beside the lake, beneath the trees, (C)
Fluttering and dancing in the breeze. (C)

The letter changes whenever the rhyme changes, and whenever a new rhyme is introduced you add a new letter.

In the poem “They Feed They Lion,” rather than end-rhyme, Philip Levine utilizes internal rhyme. Read the first stanza via this link.

In this example, Levine uses rhymes that are both internal and slant or off rather than exact: sacks, black, shafts; butter, tar. Even the numerous occurrences of “out” paired with “creosote” creates a kind of slant rhyme. Here is another example:

Not my hands but green across you now.
Green tons hold you down, and ten bass curve
teasing your hair. Summer slime
will pile deep on your breast. Four months of ice
will keep you firm.

(Richard Hugo, from “The Lady in Kicking Horse Reservoir”)

In this example, the second line contains a slant internal rhyme: “ten” and “ton,” which also rhyme with “hands” in line one. These sounds are tightly woven and where there isn’t rhyme, per se, there is assonance, similar vowel sounds, or vowel rhyme: green, tease, deep; and slime, pile, ice.


Turn to the entire Levine poem “They Feed They Lion” and perform a close reading with your ears. Note places of assonance and rhyme. How do these patterns affect your reading of the poem? How do these sounds work to create the poem’s tone of voice?

Like assonance, a term we use to describe vowel sounds, we also have terms that refer to the sounds that consonants make. Alliteration is a term used to describe a series of sounds consonants make at the beginning of or in the middle of words. In the following excerpt from “Shine, Perishing Republic,” Robinson Jeffers employs several uses of alliteration:

While this America settles in the mould of its vulgarity,

Heavily thickening to empire,

And protest, only a bubble in the molten mass, pops

And sighs out, and the mass hardens,

I sadly remember that the flower fades to make

Fruit, the fruit rots to make earth.

Out of the mother; and through the spring exultances,

Ripeness and decadence; and home to the mother.

In these first two stanzas of the poem, Jeffers’ use of mp, and f, create three strains of alliteration. In addition to alliteration, we can further label the f sounds as an occasion of consonance, what Edward Hirsch defines as “the audible repetition of consonant sounds in words encountered near each other whose vowel sounds are different”—flower-fades-fruit: fow-fay-frew.


The poet Mary Ruefle writes what she calls “erasure” poems where she will use white out to erase portions of—most of—a text to create her own poem. Find an old novel or purchase a book of prose at a book sale and try her approach. Choose to keep words you like the sounds of. Make chains of alliteration and assonance. Devote the next page to rhyme. Erase half words if you feel like it. You can also access digital versions of books made to disappear as you click away on the Wave Books web site.

Line Length

If you simply browse the poems included in any anthology, you will see all types of shapes on the page. The length of the line is one of the most important decisions a poet makes about a poem, and the decision usually comes to define a poet’s style. Robert Creeley’s poems use short lines. C. K. Williams, long. Most poets write somewhere in between. The decision of how long to make lines can be driven by a number of factors, but mostly it is chosen by prosody, the musical component of the language that projects the speaker’s voice and breath. As we’ve seen in the last chapter, where we choose to break lines also has a tremendous affect on the poem’s tone and meaning.

One of the elements that determine line length is the character of the language in which you write. English contains many iambic patterns that often sound most right on a line between four and five feet long. Lines one foot long are barely poems at all; it is difficult to create tension or musical phrases with only two beats per line. Lines with four feet are frequently used to tell stories as is the case often with Robert Frost’s poems. Longer lines lend themselves well to conversational tones, like that of Denise Duhamel’s, or in lyric poems like Larry Levis’.

Some poets like Allen Ginsberg and Charles Olson, who wrote about it in his essay “Projective Verse,” considered a line to be a unit of breath. Olson writes:

And the line comes (I swear it) from the breath, from the breathing of the man who writes, at the moment that he writes, and thus is, it is here that, daily work, the WORK, gets in, for only he, the man who writes, can declare, at every moment, the line its metric and its ending—where its breathing, shall come to, termination.

There can be no denial of the essential relationship between the poetic line and breath. Or between any carefully constructed writing and the pace at which it’s read. Just look at Olson’s passage and his use of commas, which causes us to stagger through the sentence.

Poetry is an oral art which comes fully to life when read aloud. Lines are instructions for how often and how long to pause. Like sheet music, the lines guide our pace, emphasis, and silence. If you were to read short-lined poems, however, taking a new breath at each line’s start, you’d sound like a panting dog. So, there is some room for interpretation on Olson’s assertion. Nonetheless, breath and line are intertwined, as you will see from the following examples.

As we read through these, note the different line lengths and their effects:

Here from this mountain shore, headland beyond stormy headland plunging

like dolphins through the blue sea-smoke

Into pale sea—look west at the hill of water: it is half the planet: this dome, this half globe, this bulging

Eyeball of water, arched over to Asia,

Australia and white Antarctica: those are the eyelids that never close; this is the staring unsleeping

Eye of the earth; and what it watches is not our wars.

(Robinson Jeffers, from “The Eye”)

In this excerpt from Robinson Jeffers’ poem “The Eye” we see the different affects long and short lines have on the breath. The first lengthy line full of images beyond the human—the headlands, the mountain, the shore, the dolphin, the smoke—in a long line like this we are given a sense of being overwhelmed as the images keep building and drawing out the breath until we are breathless. Compare this line to what follows two lines below: “Eyeball of water, arched over to Asia.” If you read both out loud you can feel how the length changes the way you use your lungs: long breath, short breath. The effect of the shorter line is like a quick glance—the eye open from the Pacific coast to Asia.


Click on the following link to take a look at the first four lines of Allen Ginsberg’s poem “Howl.”

Knowing that Ginsberg considered a line to be a unit of breath, it is easy for us to read the lines the way they were intended. In Ginsberg’s long lines we sense overwhelming frustration, exasperation, and urgency. There is the sense that the speaker has so much to say that he cannot contain himself, that he cannot take a breath deep enough to capture all of his thoughts. What happens when you read the last line here out loud? Try it if you haven’t. What happens is that you need to speak quickly, and this creates a voice of desperation—perfectly appropriate given the subject matter of Ginsberg’s great generational poem “Howl.” The title itself, taken from a line in Walt Whitman’s great poem “Song of Myself,” reflects the tone that Ginsberg’s lines create.

In the strange house
In the strange town
Going barefoot past the parents’ empty room
I hear the horses           the fire           the wheel           bone wings
Your voice

(Jean Valentine, from “The Messenger”)

Rather than breaking the line after words or phrases to create a pause, many poets incorporate white space into the line itself. Here, the spaces in line four visually mimic the footsteps referred to in line three, as well as create the pacing—as though the steps being taken are slow. Notice that the phrase “Your voice,” which is part of the list in line four is moved to line five. That means there must be some difference between the effect created between the phrases with white space and those created by line breaks. It seems that the pauses between the list in line four are slightly shorter, more staccato, than the pause created between “bone wings” and “Your voice.” The more poetry you read, and the more poetry you write, the more you will begin to identify the subtleties of these techniques.


On our first date, instead of holding my hand, my future-husband looked

at my palm. Here’s your fame line     your heart line    the lucky M

he said you were in danger but you are coming out of it now.

He said it like he meant it, the way the old women in the Philippines

had taught him. Now make a fist       these two little lines under your pinky

these are the two kids you’ll have.

        My sister keeps waiting

for her third baby. She has three lines. Three kids, that’s what the palm reader

at Rocky Point told her. You’ll get married next year

and you’ll have three beautiful daughters. My sister laughed and said

I‘ll get a second opinion because she was just a junior in high school

and sure she was going to college.

     On our first date my future-husband


the lines on my palm with his finger and I closed my hand around his

because it tickled. If the pad near your thumb is fleshy, he said,

it means you’re very passionate. His own palms were chubby and pink,

his brown fingers tapered and elegant. He wore a silver and turquoise ring.

He said, You’ll get married only once

but later there’ll be an affair.

Now that we’re married, he can’t find that wrinkle of infidelity.

Our palms change, he tells me, especially our right palms

that mutate through our behavior. He examines the bunch of tiny xs

that look like windshield frost, the wishbones, the spider webs,

the triangle dragon teeth.

                     My sister will most likely have that third baby.

My husband sees those three lines though my sister groans,

Two are enough. Her oldest is already fourteen, and my sister

is finally able to start taking classes at the community college.

My husband says to make everyone feel better: I was only kidding

I don’t really know that much about predictions.

               That night we all go

to Rocky Point which isn’t as fun as it used to be, which is going bankrupt,

my sister says, like everything else in Rhode Island. The rollercoaster

is broken down, the cars off the tracks, lying on their sides

like cows. And hanging from the booths’ roofs, giant Tweety Birds and Pink Panthers,

the cuddly neon elusive ones that hardly anyone ever wins.


“Lines”, from The Star-Spangled Banner by Denise Duhamel. Copyright © 1999 by Denise Duhamel. Reprinted by permission of Southern Illinois University Press. 

One of the most conversational of contemporary poets, Duhamel speaks to us like we are a long-time friend. Her voice is energetic though the lines are long. And in this poem she varies line lengths drastically but keeps to an overall pattern so it still looks uniform on the page. Once again, like other poems we’ve looked at, the form reflects and enhances the subject: the lines on our hands that palm readers use to predict our future. As we read the poem, we read the lines as though we are scanning a palm. Ironically, poems are made of lines too! In addition to the visual echo, the spaces also create pauses that mimic the way a fortune teller speaks: slowly, interpreting, considering—“He said, You’ll get married once / [space] But later there’ll be an affair.” The space also creates suspense and drama. In this excerpt, there is one line on which only one word sits: “trace.” It is the only line in the poem that contains one word. What is the effect? Why this word?


Follow the link to Gwendolyn Brooks’ poem “We Real Cool.” This short poem accomplishes a lot with its short lines and enjambment. Reflecting the theme of rebellion, each line ignores standards of syntax and ends on a word that actually starts the next sentence. The enjambment places a stress on the word “We” and therefore emphasizes the will of the speaker to identify the group. What else do you think this poem accomplishes with its lines?

If the poem is laid out so that each sentence falls on its own line, what happens to the poem’s energy? Music? Tone? Or what if you place one-and-a-half sentences on each line? Try rearranging the lines differently again and see what the effect is.

Alternatively, try another excerpt from above. Break “Howl” up into short lines, Duhamel’s poem into medium lines. Experiment with how line affects music and emphasis in meaning. Try it in one of your own poems.
