Every story, poem, or essay has the warp of its narrative voice or voices. The evidence for point of view in narrative is especially available at the beginning or the end, in any parenthetical or tangential remarks, in all the arrangements and naming of events and characters of plots and subplots, indeed, in the whole rhetorical appeal of the work. The narrator holds the camera, chooses the lighting, arranges the scenes, in fact, directs the whole script for our imagination. Point of view is not simply the opinion of the author or the narrator, but all these elements of the text under the control of a character telling the story. An actor, by changes in tone of voice, can make a hundred different plays out of the same crucial line.
Language is speech.
The reader without ears will often miss one of the most crucial aspects of literary tone, irony. The music of literature, the combinations of patterns of sound and rhythm, is called prosody in poetry. The features of sound used frequently in poetry are alliteration, assonance, consonance, onomatopoeia, and rhyme. The features of rhythm in poetry are metrical feet, caesurae, and cadence groups. In prose, style refers to the consistent pattern of an author's language choices reflected in sounds, words, phrases, sentences, and larger discourse units.
