Verbal communication is all around us. We read and hear words and sentences all the time. We consciously think in words and sometimes dream in words.
Even so, many things can be said without words; and for other things we have no words with which to express them. Music and the behaviour of animals are just two examples of non-verbal communication in its many forms that have always fascinated me. Graphic design is another. Good typography, layout and other design techniques can add a voice to a verbal or numerical message. Ideally, a voice that sings finely tuned along with your copy text.
