Read Robert Frost's "Acquainted with the Night" (p. 952). How do elements of form (like the verse structure of terza rima, rhyme, meter, repetition, alliteration, and any others) contribute to the overall mood/effect of the poem? Is there a relationship between these elements and our attitude or feelings toward the speaker? And, what is the effect of having the first and last line be the exact same? Does our understanding of the line change over the course of the poem at all?
