Definition
A sestet is a stanza of six lines, often forming the second part of an Italian sonnet. It typically provides a resolution, reflection, or response to the problem presented in the octave. Think of it as the punchline of a poetic joke π. The rhyme scheme varies but commonly includes CDECDE or CDCDCD. Unlike the octave, the sestet focuses on providing closure or insight. It completes the thought or argument begun in the first eight lines.
