What is iambic pentameter and how does it influence the rhythm of a Shakespearean sonnet?

• A. Five iambs per line (unstressed-stressed); creates a rising, formal rhythm typical of Shakespearean verse.
• B. Ten syllables per line, all stressed.
• C. A fixed meter with stressed final syllable only.
• D. It's blank verse with no rhyme.

Answer: (D)

Iambic pentameter is five iambic feet per line, with each foot containing an unstressed syllable followed by a stressed one. That results in about ten syllables per line and a da-DUM rhythm that gives Shakespearean verse its steady, dignified pulse. In a Shakespearean sonnet, this meter runs through every line, producing a formal cadence that helps carry the argument and imagery with clarity and grace. Poets sometimes vary the pattern for emphasis—a few substitutions here and there keep the verse from feeling sing-song—yet the basic five-foot, unstressed-stressed structure remains the backbone of the line. The sonnet’s rhyme scheme (four interlocking quatrains followed by a concluding couplet) complements the meter, weaving sound and sense into a compact, musical whole. Descriptions that claim the form is just ten syllables all stressed miss the essential lightness and lift of the unstressed-then-stressed pattern, while calling it blank verse ignores the rhyme that Shakespearean sonnets rely on. A description that treats it as a fixed meter with a final-stress rule also misstates how the feet and stresses operate.
