Identify the structural parts of a Shakespearean sonnet (three quatrains and a couplet, rhyme scheme, volta) and explain how the form's turn changes the poem's argument.
A sonnet is a fourteen-line poem with a fixed structure that forces compression -- there is no room to wander. The Shakespearean sonnet is built from three quatrains (four-line units) rhyming ABAB CDCD EFEF, followed by a rhyming couplet (GG). The volta, or "turn," is the point where the poem's argument shifts, often right at the couplet.
Sonnet 18 spends its three quatrains comparing the beloved to a summer's day and finding summer wanting -- too short, too rough, too changeable. The volta arrives at the couplet, where the argument pivots from comparison to a bolder claim: the poem itself will outlast summer and make the beloved immortal simply by being read. This turning structure becomes essential background for Shakespeare's plays, which lean on the same compressed, argument-then-turn shape inside individual speeches.
Mastery looks like: They can count and label a sonnet's structural parts and identify the specific line where the volta occurs and what shifts there.
Common stumbles: Treating the volta as just "the ending" rather than the specific moment the argument changes direction; missing that the couplet makes a different claim than the quatrains, not just a summary of them.
