Answer:
The rhyming scheme of Sonnet 73 is abab cdcd efef gg with the lines witten in the iambic pentameter form. The whole poem also has the regular three quatrains and ends with a couplet.
Step-by-step explanation:
William Shakespeare's famous sonnet Sonnet 73 deals with the theme of growing old, time, and mortality. This sonnet, like a regular one, is composed of three quatrains and a couplet that ends the whole sonnet, written in an iambic pentameter form.
The rhyming scheme of the sonnet is in the regular abab cdcd efef gg form, with the rhymes in full- "behold/cold" "hang/sang" etc. This form of Shakespearean sonnet also has the full iambic pentameter form, with almost all lines following the pattern of an unstressed and stressed syllable without any variation. And while the quatrains bring the main theme of old age and man's mortality, the ending couplet provides a melodious aspect to the whole sonnet.
