Loosening the Line
English metre counts feet, not syllables. A foot is a stress pattern, and the iamb, unstressed then stressed, is the default because it matches ordinary English phrasing. Iambic pentameter is five iambs, therefore ten syllables, and it has dominated English verse since Chaucer for the simple reason that it sits close to speech without being speech.
John Keats (1795–1821) uses the line at its most saturated. The odes of 1819 — Ode to a Nightingale, Ode on a Grecian Urn — put an enormous weight of sensory detail onto a regular metre, and the regularity is what makes the density bearable. The urn ode ends with a claim that has been argued over ever since: Beauty is truth, truth beauty, a statement the poem has earned and then, in the same breath, attributes to an object that cannot speak.
Arthur Rimbaud (1854–1891) breaks the French line from inside. The alexandrine is twelve syllables with a caesura at six, and its symmetry had been the backbone of French verse for three centuries. Rimbaud displaces the caesura, then abandons metre altogether in the prose poems of Illuminations. He wrote everything before he was twenty-one and then stopped writing entirely, which is either the most complete artistic statement of the century or a fact about a difficult young man, depending on who is telling it.
Walt Whitman (1819–1892) abandons the count outright. Leaves of Grass (1855, revised until 1892) has no fixed syllable count and no fixed stress count; its organisation is syntactic: parallelism, anaphora, catalogue. A Whitman line ends where a breath or a clause ends. This is not the absence of form. Repeating a grammatical structure is as strong an organising device as rhyme, and it is the reason the poems hold together without metre.
Rubén Darío (1867–1916) leads modernismo, the first literary movement to travel from Latin America to Spain rather than the other way. He revives abandoned classical metres, imports French symbolist music into Spanish, and expands the metrical repertoire enormously, the opposite strategy from Whitman's, arriving at a comparable freedom.
| Poet | The count | What replaces or extends it |
|---|---|---|
| Keats | Iambic pentameter, 10 syllables | Nothing, saturation within the form |
| Rimbaud | Alexandrine, 12 with caesura at 6 | Displacement, then prose poem |
| Whitman | None | Parallelism, anaphora, catalogue |
| Darío | Many, including revived metres | Expansion of the repertoire |
Common pitfall: calling free verse "verse without rules". Whitman's lines are organised as tightly as any sonnet, the organising principle is grammatical rather than metrical, and removing it collapses the poem just as surely as breaking a rhyme scheme would.
