SESTETT, the name given to the second division of a sonnet, which must consist of an octave, of eight lines, succeeded by a sestett, of six lines. In the usual course the rhymes are arranged abc \ abc, but this is not necessary. Early Italian sonnets, and in particular those of Dante, often close with the rhyme-arrangement abc \ cba; but in languages where the sonority of syllables is not so great as it is in Italian, it is dangerous to leave a period of five lines between one rhyme and another. In the quatorzain, there is properly speaking no sestett, but a quatrain followed by a couplet, as in the case of Shakespeare's so-called " Sonnets." Another form of sestett has only two rhymes, ab \ ab \ ab; as is the case in Gray's famous sonnet " On the Death of Richard West." The sestett should mark the turn of emotion in the sonnet; as a rule it may be said that the octave having been more or less objective, in the sestett reflection should make its appearance, with a tendency to the subjective manner. For example, in Matthew Arnold's ingenious " The Better Part," the rough inquirer, who has had his own way in the octave, is replied to as soon as the sestett commences:
" So answerest thou ? But why not rather say:
' Hath Man no second life ? Pitch this one high. More strictly, then, the inward judge obey I Was Chnst a man like us? Ah I let us try If we, then, too, can be such men as he ! ' ' Wordsworth and Milton are both remarkable for the dignity with which they conduct the downward wave of the sestett in their sonnet. The French sonneteers of the 16th century, with Ronsard at their head, preferred the softer sound of the arrangement aab | ccb \. The German poets have usually wavered between the English and the Italian forms.
