Prose, poetry, and the speaker
Prose serves as the transparent language of manuals and essays where literal communication is the primary goal. Poetics steps away from this straightforward message to analyze how word choice and structural rhythm build a unique experience instead of just trading information.
When listening to a poem, the voice delivering the lines is not automatically the author. In poetics, this persona is called the Speaker, allowing an author to adopt specific perspectives regardless of their personal background.
Understanding this distinction helps readers look beyond literal autobiographical facts to examine how a constructed persona delivers lines. A young poet can write convincingly from the perspective of an old soldier without having experienced war firsthand.

In poetics, we call this the Speaker—the persona or character created to deliver the lines.

Consonants, vowels, and acoustic textures
Consonants provide the structural bones of words while creating sonic textures through repeated sounds like alliteration and consonance. Plosive consonants stop airflow completely and release it in a burst to add energetic weight to a line.
In contrast, sibilants use continuous airflow through a narrow gap to establish quiet or mysterious atmospheres. Vowels supply color and emotional resonance through techniques like assonance, helping control the pace of a line.
Poets combine these specific vowel lengths and consonant types to match the thematic mood of the subject. A harsh scene relies on cacophony, while smooth phrasing achieves a melodic euphony designed for harmony.

While consonants provide the structure and 'bones' of a word, vowels provide the color and the emotional resonance.

Rhyme, rhythm, and structural repetition
Poets use rhyme to create a sense of completion and stability when lines conclude as the ear expects. Perfect rhymes match vowel and ending consonant sounds exactly, whereas slant rhymes offer a near-miss that introduces intentional tension.
Repetition drives emotional intensity by establishing a predictable beat that the human ear naturally follows. When a poet repeats words at the beginning of consecutive lines, the technique acts like a hammer driving an idea deeper.
A refrain returns at specific intervals like an anchor, maintaining a steady rhythmic expectation. Combining these patterns allows a writer to control the reader's breath and focus with absolute precision.

When a poet repeats the same word or phrase at the beginning of several lines in a row, it is called Anaphora.
