Creating a metaphor is like composing music, and metaphors affect us in the same way music does. A tune consists of notes in a relationship, it can be transposed higher or lower and will still be the same tune, provided the notes still have the same relationships to each other, the same distances between them, as they had in the original tune. At a deeper level, these notes combine to make chords, and a sequence of chords will have certain relationships to each other. Musical rhythm is how long different notes last relative to each other. Music is meaningful in a different way to language. It goes straight to the unconscious; the left brain has nothing to catch on to.
