Final answer:
A metric verse possesses a defined metrical pattern and rhyme scheme, unlike free verse which may employ a more fluid structure.
Step-by-step explanation:
A metric-verse has a definitive metrical pattern and a rhyming scheme. Metric verse in poetry refers to the structured organization of lines and stanzas that create a rhythm through stressed and unstressed syllables. Unlike free verse, which can have a more sporadic utilization of meter and rhyme, metric verse adheres to a pre-determined pattern that can include various poetic forms such as sonnets, with its fourteen lines and volta, or ballads, which commonly use an AABB or ABCB rhyme scheme.
For example, Samuel Taylor Coleridge's "The Rime of the Ancient Mariner" uses a quatrain, a four-line stanza, with an ABCB rhyme scheme to convey its narrative. Traditional tercets, like those in Dante's Divine Comedy, follow an ABA, BCB rhyme scheme. Likewise, quatrains with an ABAB or ABCD rhyme scheme are commonplace and play a significant role in structuring a poem.
Meter and rhyme help to tie lines and stanzas together, creating a cohesive and rhythmic flow. This contrasts with free verse, which often seems to lack a pattern or organization but may still employ certain metrical and rhyme techniques to link lines and convey thematic coherence.
