the music in words

Is there another language, just as exacting for the author, as a language of words? Is there a language of actions, a language of sounds -- a language of word-as-part-of movement, of word-as-lie, word-as-parody, of word-as-rubbish, of word-as-contradiction, of word-shock or word-cry? If we talk of the more-than-literal, if poetry means that which crams more and penetrates deeper -- is this where it lies?
