Octave (poetry)
An octave is a verse form consisting of eight lines of iambic pentameter or of hendecasyllables. The most common rhyme scheme for an octave is abba abba.
An octave is the first part of a Petrarchan sonnet, which ends with a contrasting sestet. In traditional Italian sonnets the octave always ends with a conclusion of one idea, giving way to another idea in the sestet. Some English sonnets break that rule, often to striking effect. In Milton's Sonnet 16, the sestet begins early, halfway through the last line of the octave:
Patience's too-quick reply intrudes upon the integrity of the octave. Since "prevent" also means "anticipate," it is as if Patience is giving the answer before the question is asked.
