In poetry, what is a stanza?

A stanza is defined as a section of a poem, which typically consists of a grouped set of lines that are often separated from other stanzas by a space. Stanzas serve to organize the poem's thoughts, themes, or ideas, much like paragraphs do in prose. Each stanza can have its own rhythm, rhyme scheme, and length, contributing to the overall structure and flow of the poem.

The other options represent different poetic concepts: a type of rhyme scheme refers to the pattern of rhymes at the end of lines, a metrical foot is a specific unit of measurement in poetry that describes the rhythm, and a narrative voice pertains to the perspective from which the poem is told. None of these options capture the essence of what a stanza is as clearly as the definition of a stanza as a section of a poem.
