Let us start with analyzing the poem's basic structure. The poem is comprised of four stanzas. Each stanza is six lines long, which is a sextain in poetry language. What is unique about each sextain is that each one contains a tercet. A tercet is a set of three lines. The lines do not have to always rhyme, but Wyatt makes his tercet stand out within each stanza by having the same rhyme:
That hath given thee my heart
Never for to depart,
Nother for pain nor smart;
Each stanza begins with "And wilt thou leave me thus?" That question is repeated in line 5 of each stanza, and the final line in each stanza is "Say nay, say nay!" All of this together gives each stanza the rhyme scheme of ABBBAC.
