Prose and poetry are different in construction. You can lie back and read prose, and you can read it fast. Poetry on the other hand, requires a different kind of attention and concentration … the effect it has on the ear and the imagination.
Prose uses the medium of language whilst poetry serves language and explores it.
The reader does not need a technical vocabulary to read poetry, only a voice in the head or out loud which can deliver the sounds.
In poetry much of the sense and most of the pleasure resides in the sounds the poem make.
