For modern poetry rhyme means impoverishment of language. Visual level includes Images. Pictures out of words. All this creates a new language which tends to have its own meamning, its own field . Semantics has many tools of fracture or anatomization of meaning.
New word attracts the meaning pulling it out of reader's unconsciousness.
And only by encounter of sounds, images and words, by interaction of conscious and unconsciousness a poem may be created. It must not only delight the eye and ear but call forth the intension, pulsate in space and time.
