As chapter is to prose, so ...is to poetry

As chapter is to prose, so stanza is to poetry. A chapter is a division of prose that groups together related ideas and events, while a stanza is a similar division in poetry that groups together lines of verse. Just as a chapter can be composed of multiple paragraphs, a stanza can be composed of multiple lines. Stanzas are often used to organize the themes and structure of a poem, and they can vary in length, rhyme scheme, and meter.
