Struggling to Understand the Style of the Canticle of the Winged Sisters

Disclaimer: I have only a limited knowledge of epic poetry, derived from study of the Hebrew Bible (Protestant-Christian Old Testament) and High School British Literature. End Disclaimer.

I'm struggling to find any sort of cohesion in the Canticle. Firstly, there seems to be no rhyme scheme, neither across lines, or pairs of lines, or corresponding lines between verses (i.e. I - 1 , II - 1 being paired, etc). That I accept; rhyme is unnecessary for great poetry, John Milton presiding over that judgment. But there's also no meter; the lines are so varied in length that it feels like it was originally written by a storyteller who was merely trying to find the most dramatic way to say each sentence.

After finding these things working against my comprehension, I turned to the definition of a canticle: From Wikipedia (it serves my purpose better): A canticle (from the Latin canticulum, a diminutive of canticum, "song") is a hymn, psalm or other song of praise taken from biblical or holy texts other than the Psalms.

"Wonderful," I think, dredging up a little bit of knowledge about Ancient Hebrew Poetry (i.e. the book of Psalms or the Song of Solomon). Generally, the style is composed of couplets, with an introductory line making a point and then the second line reinforcing, expanding, or explaining the first. Looking through the Canticle of the Winged Sisters, I could see the couplets. Then I found the first line out of place. Then the next. At many points throughout the canticle there are lines that would be couplets but are separated by periods. There are other lines that have no couplet, confusing me as to the intent outside of needing/wanting to say something and being unable (or undesirable) to find a pair line for it.

Thus I am stuck. Is this a canticle proper and I don't know it? Is it some sort of modern style I don't know? Are there levels to Hebrew poetry I'm forgetting? Is this simply a modern poem that eschews established style to forge a new path? Remember I'm no English major, and while I love poetry, I most definitely don't know everything.

For me, personally, this poem struck no chords. I couldn't get into it, and want to know more so that I can yet attempt to respect it (or maybe at least the ?experimental nature? of it).
