The volta is the moment a poem changes direction. The word is Italian for "turn," and it names something that happens in almost every lyric poem ever written, whether or not the poem knows it is a sonnet, whether or not the poet has heard the term. The turn is not a technical feature of certain fixed forms — it is the basic structural principle of lyric poetry. A poem that does not turn is not a poem; it is a list.
Understanding the volta is understanding how poems think. Not what they say, but how they move — how they arrive at something they could not have arrived at without the journey of the preceding lines. The volta is the moment of arrival. Everything before it is the approach. Everything after it is the view.
What the volta is
In its most codified form, the volta appears in the sonnet. The Petrarchan sonnet divides into an eight-line octave and a six-line sestet, with the volta at the boundary — the ninth line marks a shift in argument, emotion, or perspective. The Shakespearean sonnet delays the turn until the final couplet, building pressure through three quatrains before releasing it in two lines. Different forms, same principle: the poem establishes something, then turns on it.
But the volta is not confined to sonnets. Every elegy has a turn — from grief toward acceptance, or from acceptance back toward grief, or from the public to the private, or from the dead to the living. Every meditation has a turn — the moment when contemplation produces insight rather than further contemplation. Every lyric poem that works has a moment when the terms of the poem change, when the speaker arrives somewhere they could not have reached without the poem that preceded them.
“The turn is not a technical feature of fixed forms. It is the basic structural principle of lyric poetry. A poem that does not turn is not a poem — it is a list.”
The volta in the sonnet
The sonnet is the form in which the volta is most explicitly theorised, and the form in which you can most easily see it working. In Shakespeare's Sonnet 18 — "Shall I compare thee to a summer's day?" — the volta comes at line 9: "But thy eternal summer shall not fade." For eight lines, the poem has been establishing summer's inadequacy as a comparison. The ninth line turns: unlike summer, the beloved will not fade. But then the poem turns again at the couplet, and we realise that it is not the beloved but the poem itself that grants this permanence. The final couplet is the real volta: "So long as men can breathe or eyes can see, / So long lives this, and this gives life to thee." The poem is not a love poem. It is a poem about the poem.
This layered volta — a turn that itself gets turned — is characteristic of the best sonnets. The reader thinks they know where the poem is going at line 9, and then the couplet reveals that the poem was going somewhere else entirely. Our close reading of Sonnet 18 explores this in detail.
Types of volta
The volta takes many forms depending on what the poem is doing. The argumentative turn is the most common in formal poetry: the poem poses a problem or question in the first movement, and the second movement answers or complicates it. The emotional turn is more common in confessional and lyric poetry: the poem moves from one emotional register to another, from grief to anger, from anger to exhaustion, from exhaustion to something that might be peace.
The perspectival turn shifts the angle of vision — from the speaker to the observed, from the present to the past or future, from the particular to the general. The tonal turn changes the register of the language itself — from formal to colloquial, from lyric to plain, from elevated to flat. And the imagistic turn introduces an image that recontextualises everything that preceded it — the final image that makes you re-read the whole poem with different eyes.
The volta in free verse
In free verse, the volta is less predictable in its placement but no less essential to the poem's function. It can come anywhere — in the middle of a poem, at the end of a stanza, in a single word that changes the terms of everything around it. The free verse poet must create the sense of turning without the formal scaffolding that tells the reader when to expect it.
This is harder than it sounds. The volta in a sonnet is anticipated — the reader knows it is coming even if they do not know exactly what form it will take. The volta in free verse must be earned entirely by what precedes it and felt entirely in the moment. When it works, it produces the most powerful version of the effect: the reader did not see it coming, and yet it feels inevitable.
How to recognise and write the volta
To recognise a volta, look for the moment when the poem's direction changes. Not when the subject changes — the subject may remain constant — but when the speaker's relationship to the subject changes, or when the terms of the poem shift, or when a new perspective opens. Words like "but," "yet," "and yet," "however," "still," and "though" often signal a volta, though the turn can happen without any such marker at all.
To write one, ask yourself: what does this poem know at the end that it did not know at the beginning? If the answer is nothing, the poem has not turned. The turn does not need to produce resolution — many of the best poems end in a more complex uncertainty than they began with — but it needs to produce movement. Something must change. The poem that ends where it began is not yet finished.
