Language is music. Written words are musical notation. The music of a piece of fiction establishes the way in which it is to be read, and, in the largest sense, what it means. It is essential to remember that characters have a music as well, a pitch and tempo, just as real people do. To make them believable, you must always be aware of what they would or would not say, where stresses would or would not fall.
