sonnets "may not be in an order which is absolutely correct but no one can deny that they are related and that they do show some development some 'story' even if incomplete and unsatisfactory". Form and structure Sonnet 1 has the traditional characteristics of a Shakespearean sonnet—three quatrains and a couplet written in iambic pentameter with an ABAB CDCD EFEF GG rhyme scheme. Many of Shakespeare's sonnets also reflect the two-part structure of the Italian Petrarchan Sonnet. In this type of sonnet (though not in Sonnet 1) "the first eight lines are logically or metaphorically set against the last six [and] an octave-generalization will be followed by a particular sestet-application, an octave question will be followed by a sestet answer or at least a quatrain answer before the summarizing couplet". In lines one through four of this sonnet, Shakespeare writes about increasing and references memory. Here, Shakespeare chooses to rhyme "increase" and "decease", "die" and "memory" and then proceeds to use "eyes" and "lies", "fuel" and "cruel" as rhymes in the second quatrain (lines five through eight). In lines five through twelve, Shakespeare shifts to famine and waste. Carl Atkins highlights Shakespeare's inventiveness in the second quatrain, where the sonnet takes on a less-regular rhythm: "We note Shakespeare's consummate ability to mimic colloquial speech so that the sonnet sounds personal and conversational, rather than sententious. Rhythm has an important role here. Thus, we have the triple emphasis produced by the final spondee of line 5, so effective after the regular iambic pentameter of all that precedes it. This is then followed by the flowing trochee-iamb that begins the next line, a combination that will be repeated frequently". In the third quatrain, the key rhyming words given by the speaker are: "ornament" and "content", and "spring" and "niggarding"; additional images are presented in this quatrain, such as "fresh", "herald", "bud", "burial", and the oxymoron "tender churl". Other words and themes the speaker uses are explained by Helen Vendler: "The concepts – because Shakespeare's mind works by contrastive taxonomy – tend to be summoned in pairs: increase and decrease, ripening and dying; beauty and immortality versus memory and inheritance; expansion and contraction; inner spirit (eyes) and outward show (bud); self-consumption and dispersal, famine and abundance". Shakespeare uses these words to make "an aesthetic investment in profusion". The sonnet ends with a couplet: two consecutive rhyming lines. Each line contains ten syllables, and
