As I see it, poetry is not prose simply because poetry is in one way or another formalized. It is not poetry by reason of its content or ambiguity but by reason of its allowing musical elements (time, sound) to be introduced into the world of words. Thus, traditionally, information no matter how stuffy (e. g. the sutras and shastras of India) was transmitted in poetry. It was easier to grasp that way. Karl Shapiro may have been thinking along these lines when he wrote his Essay on Rime in poetry.

The highest purpose is to have no purpose at all. This puts one in accordance with nature, in her manner of operation.

Before leaving the earth altogether, let us as: How does Music stand with respect to its instruments, their pitches, the scales, modes and rows, repeating themselves from octave to octave, the chords, harmonies, and tonalities, the beats, meters, and rhythms, the degrees of amplitude (pianissimo, piano, mezzo-piano, mezzo-forte, forte, fortissimo)? Though the majority go each day to the schools where these matters are taught, they read when time permits of Cape Canaveral, Ghana, and Seoul. And they’ve heard tell of the music synthesizer, magnetic tape. They take for granted the dials on radios and television sets. A tardy art, the art of Music. And why so slow? Is it because, once having learned a notation of pitches and durations, musicians will not give up their Greek? Children have been modern artists for years now. What is it about Music that sends not only the young but adults too as far into the past as they can conveniently go? The module? But our choices never reached around the globe, and in our laziness, when we changed over to the twelve-tone system, we just took the pitches of the previous music as though we were moving into a furnished apartment and had no time to even take the pictures off the walls. What excuse? That nowadays things are happening so quickly that we become thoughtless? Or were we clairvoyant and knew ahead of time that the need for furniture of any kind would disappear? (Whatever you place there in front of you sits established in the air.) The thing that was irrelevant to the structures we formerly made, and this was what kept us breathing, was what took place within them. Their emptiness we took for what it was – a place where anything could happen. That was one of the reasons we were able when circumstances became inviting (chances in consciousness, etc.) to go outside, where breathing is child’s play: no walls, not even the glass ones which, though we could see through them, killed the birds while they were flying.
