A sestet consisting of an eight-syllable rhymed couplet followed by a seven-syllable line that has cross-rhyme to the couplet in the middle and rhymes with the sixth line of the couplet followed by another eight-syllable couplet and seven-syllable line with cross rhyme to lines four and five. Eight and seven syllable mixed sestet verse, with syllable and rhyme pattern: * * * * * * * A * * * * * * * A * * A * * * B (A could shift position slightly) * * * * * * * C * * * * * * * C * * C * * * B (C could shift position slightly) According to one soi-disant authority, the cross-rhyming must be in the middle of lines three and six.
