The ninth line of this sonnet, i.e., the first line of the sestet marks a turn in mood or stance whether or not there is a satisfactory conclusion. The octave proposes a problem or question, and the sestet generally proposes the solution, or leads toward a conclusion. The Italian sonnet, which was created first, is the combination of an octave (eight lines broken into two quatrains) and a sestet (six lines broken into two tercets). All sonnets, whether Italian or English, generally are written in iambic pentameter. Though the definition of sonnet states that the poem must have fourteen lines, there are a few variations with this form.
