What Are the Main Features of the Petrarchan Sonnet?

A sonnet is a 14-line poem, usually about love or a lover, with a specific form. Academics often divide sonnets into two categories: the Petrarchan sonnet and the English sonnet. The Petrarchan sonnet, also sometimes called the Italian sonnet, is named after the 14th-century poet Francesco Petrarch. The two forms are largely similar, but they do have a few important distinctions.

Standard Length and Division

The easiest way to identify a sonnet is by its length -- all sonnets are 14 lines long. In a Petrarchan sonnet, the lines are divided into three parts: two quatrains and a sestet. The two quatrains, or four-line units, comprise the first eight lines. Collectively, these lines are known as the octave. The final six lines are called the sestet. The use of a sestet distinguishes the Petrarchan sonnet from the English sonnet, which uses three quatrains and a two-line couplet at the end. These units of the sonnet are each bound together by a specific rhyme scheme.

Rhyme Scheme

The Petrarchan sonnet typically follows a relatively rigid rhyme scheme. The octave follows the pattern ABBA ABBA. A key difference in rhyme scheme between the Petrarchan and English sonnet is the rhyme scheme of the initial quatrains. The English sonnet almost always follows an ABAB pattern for its three quatrains, instead of the Petrarchan ABBA for its two quatrains. The sestet follows a more flexible rhyme scheme, featuring either two or three new rhyming sounds. The most common pattern is CDECDE, but many variations are possible. Some poets even prefer to end with couplets, although Petrarch himself reportedly never did.

The Volta

Between the octave and the sestet, a Petrarchan sonnet usually shifts its tone or focus. This change is called the "volta," or "turn." For example, the octave of William Wordsworth's sonnet "London, 1802" decries the decline of the English race. The sestet then praises the poet John Milton for his possession of the supposedly lost qualities of the English. According to Sonnet Central, the volta may be the single most important feature of the sonnet. The shift in ideas is mirrored by the shift in rhyme scheme as the poem moves from the ABBA pattern of the quatrain to the CDECDE pattern of the sestet.

Common Themes and Devices

Love is the most common subject of Petrarchan sonnets, but these poems may also heap blame or scorn on a person, according to Dallas Baptist University. Whether the poem centers on love or blame, it typically makes an elaborate and lengthy comparison between a person and an thing or idea. For example, Charles Tennyson Turner's poem "Missing the Meteor" compares a lover to a shooting star. Sonnets thus rely heavily on the literary devices of metaphor and simile. Another common trope is personification, the ascription of human qualities to objects or ideas.
