Sonnet corona is a sequence of seven interlinked sonnets where the last line of each sonnet becomes the first line of the next, creating a circular chain. The final sonnet's last line repeats the opening line of the first sonnet, completing the crown or corona. This demanding form requires maintaining sonnet structure across all seven poems while ensuring each linking line functions effectively in both its concluding and opening positions. The corona typically explores a sustained theme or subject across its 98 lines, with each sonnet developing different aspects. The form demonstrates virtuosity and commitment, creating complex interwoven meditation through rigorous formal constraint.

A Sonnet corona is a sequence of 14 sonnets where the last line of each becomes the first of the next, and the final sonnet ends with the first line of the first—forms a circular, interlinked structure.
