Final answer:
Closed form poetry, such as a sonnet, adheres to specific rules of rhyme and meter, while open form poetry, like free verse, offers poets freedom from these constraints.
Step-by-step explanation:
The difference between closed and open form poetry lies in their structure and adherence to rules. Closed form poetry follows specific rhyme and meter patterns, coming with a set of traditional rules that dictate its structure. An example of closed form poetry is a sonnet, which typically adheres to a strict 14-line structure with a specific rhyme scheme and rhythm. In contrast, open form, often known as free verse, does not conform to traditional rhyme and meter patterns, giving poets more freedom in crafting their poems. An instance of open form poetry is free verse, which defies fixed patterns, allowing the poet to manipulate stanzas, lines, rhythm, and rhyme in a more spontaneous and organic way.
