Prosody is the branch of linguistics and literary study concerned with the versification of poetry. It encompasses the analysis of rhythm, stress, and intonation. While scansion is the act of analyzing the meter, prosody is the broader field of study covering these structural elements.

Meter is the fundamental rhythmic structure of a line of poetry, determined by the pattern of stressed and unstressed syllables. It provides the underlying pulse of the poem, which is essential for maintaining the rhythmic integrity of various poetic forms and structures.

A quinzaine is a specific poetic form consisting of exactly fifteen lines. It is a relatively rare structure in English prosody, often used to describe a stanzaic arrangement that adheres to this specific line count, distinct from more common forms like the sonnet or the quatrain.

Prosody is the systematic study of the versification of poetry, encompassing rhythm, meter, stress patterns, and intonation. While scansion is the act of analyzing a specific poem's meter, prosody is the broader field of study that defines the rules and structures governing poetic form.

Iambic pentameter consists of five iambs per line, where each iamb is an unstressed syllable followed by a stressed syllable (da-DUM). The line 'To be or not to be, that is the question' perfectly follows this ten-syllable rhythmic pattern, making it a classic example of the meter used in Shakespearean drama.

Unrhymed iambic pentameter is commonly referred to as 'blank verse'. It consists of lines of five iambic feet without a rhyme scheme. This form became the standard for English dramatic and epic poetry because it closely mimics the natural rhythms of the English language while maintaining a formal structure.

Both 'L'Allegro' and 'Il Penseroso' are written primarily in iambic tetrameter, often arranged in rhyming couplets. This rhythmic choice provides a light, musical quality that suits the pastoral and contemplative themes of the poems. The meter is consistent throughout both works, emphasizing their status as balanced companion pieces.

In prosody, meter is the systematic arrangement of stressed and unstressed syllables in a line of verse. It creates the rhythmic structure that gives poetry its characteristic cadence and musical quality. Common meters in English poetry include iambic pentameter, where each line consists of five pairs of alternating unstressed and stressed syllables, providing a consistent beat that organizes the flow of language.

A caesura is a rhythmic pause or break within a line of poetry, often occurring in the middle of a line. In Old English poetry, it is a structural necessity that divides the alliterative line into two distinct half-lines, providing the cadence and breath required for oral recitation.

Blank verse is a literary term for poetry written in unrhymed iambic pentameter. It is defined by its consistent meter rather than a rhyme scheme. It has been a dominant form in English dramatic and epic poetry, notably used by Shakespeare and Milton, because it closely mimics the natural rhythms of spoken English.
