All Poems are Triangles

Form in poetry is more than just meter, stanza, and line break. It’s also a way of thinking. It’s the direction, pace and energy of the poem, and one of the main ways a writer can direct the reader’s experience. And, at least in my way of understanding, it’s also not something that’s simply visible on the page or scannable across a line. Shape and structure is metaphysical as much as it’s physical.

And this all is a way into my idea that all poems are triangles. Poems are kinds of vessels of energy. You cram a bunch of things in one end (images, concepts, sounds, ideas) and something else emerges from the other. Like a triangle, poems have a wide end and a narrow end. From a content point of view, a poem can start with a small point (a particular image, moment, or idea) and then expand, the way an ant hill expands as it gets to the base. Or the poem can start out large, with a wide idea that that covers everything, then narrows to make a particularly sharp point at the end. Think of that as a large funnel you dump the poem into, and it comes out a small opening at the bottom.

The most typical, at least in my experience (and in my own writing) is the poem/triangle that starts small and gets wider as it develops. Remember, I’m talking about the idea structure, not the line length or any other kind of structure. Often you’ll see a poem use some small moment or image as a trigger, which leads to another, and another, and as the images build, so does the idea and consequence of the poem. Take this William Stafford poem as an example:

At the Bomb Testing Site

By William E. Stafford

At noon in the desert a panting lizard

waited for history, its elbows tense,

watching the curve of a particular road

as if something might happen.

It was looking at something farther off

than people could see, an important scene

acted in stone for little selves

at the flute end of consequences.

There was just a continent without much on it

under a sky that never cared less.

Ready for a change, the elbows waited.

The hands gripped hard on the desert.

It starts with the lizard just sitting on a road panting, but almost immediately the poem starts to expand (“waited for history”) until at the end the poem seems to encompass the whole future in it.

This Jane Hirshfield poem does a very similar thing. It begin with on a small point, the young tree, and ends wide with “immensity taps at your life.”


By Jane Hirshfield

It is foolish

to let a young redwood

grow next to a house.

Even in this

one lifetime,

you will have to choose.

That great calm being,

this clutter of soup pots and books—

Already the first branch-tips brush at the window.

Softly, calmly, immensity taps at your life.

This poem by Natasha Trethewey, does the opposite. It starts with a large idea, almost the way an essay may start with a thesis statement, and then the poem progresses with details to support or explain the first idea, finally landing on a point, like a gymnast beginning with a large opening move then landing solidly on small, steady feet.

Theories of Time and Space

by Natasha Trethewey

You can get there from here, though

there’s no going home.

Everywhere you go will be somewhere

you’ve never been. Try this:

head south on Mississippi 49, one-

by-one mile markers ticking off

another minute of your life. Follow this

to its natural conclusion—dead end

at the coast, the pier at Gulfport where

riggings of shrimp boats are loose stitches

in a sky threatening rain. Cross over

the man-made beach, 26 miles of sand

dumped on the mangrove swamp—buried

terrain of the past. Bring only

what you must carry—tome of memory,

its random blank pages. On the dock

where you board the boat for Ship Island,

someone will take your picture:

the photograph—who you were—

will be waiting when you return.

Note that the wide parts of a poem tend to be statements or metaphors, while the narrow parts tend to be images. Metaphors, especially similes, are expansion devices. Look at what a simile does—it takes one thing, compares it to something else, and creates a third space.

First, of course this silly idea about triangles doesn’t always work. Some poems are straight columns. Some are so gerrymandered that you can’t even name their shape. So how do I use this concept anyway?

Thinking of the shape of a poem’s idea helps me visualize how its energy and pace work, how it tightens and speeds up, or comes to a pause. In composition this can help me overcome roadblocks. If a poem seems to be stalled at some point, not moving the way I want, I’ll overlay the triangle to it and test which direction the poem is pointing, what kind of base or point is has, and where the break in its energy is. This can sometimes help me solve problems I otherwise couldn’t see. Sometimes when I’m stuck on a poem but can’t seem to see the shape, I’ll try to carve a triangle out of it—the way a sculptor sees a shape inside a block of stone.

It also helps me when reading poems, especially when I want to analyze how a poem works. I’ll look at the opening and closing to figure out which is the wide end and which is the narrow end. Is the narrow end a landing or the tip of a funnel. Does the wide base allow the idea to keep growing beyond the poem?
