In poetry, a meter refers to the rhythmic structure created by the arrangement of stressed and unstressed syllables in a line of verse.
Meter contributes to the overall musicality and cadence of a poem. Common meters include iambic pentameter, with five pairs of alternating unstressed and stressed syllables per line, and trochaic tetrameter, featuring four pairs of stressed and unstressed syllables.
The choice of meter can influence the mood, pace, and emphasis within a poem, allowing poets to shape the flow and impact of their work.
