The form of Shakespeare’s Sonnets.

Shakespeare’s ‘Sonnets’ ignore the somewhat complex scheme of rhyme adopted by Petrarch, whom the Elizabethan sonnetteers, like the French sonnetteers of the sixteenth century, recognised to be in most respects their master. Following the example originally set by Surrey and Wyatt, and generally pursued by Shakespeare’s contemporaries, his sonnets aim at far greater metrical simplicity than the Italian or the French. They consist of three decasyllabic quatrains with a concluding couplet, and the quatrains rhyme alternately. [95b]

A single sonnet does not always form an independent poem. As in the French and Italian sonnets of the period, and in those of Spenser, Sidney, Daniel, and Drayton, the same train of thought is at times pursued continuously through two or more. The collection of Shakespeare’s 154 sonnets thus presents the appearance of an extended series of independent poems, many in a varying number of fourteen-line stanzas. The longest sequence (i.-xvii.) numbers seventeen sonnets, and in Thorpe’s edition opens the volume.
