On the question of accessibility, I'm reminded (of all things) of the blurb Alice Notley has on the back of Bill Luoma's Works & Days. She writes basicly (I don't have it handy) that a book should be readable. This seems to tie in with how easily a work can be accessed by it's audience, that is understood on some level. Music is more visceral in how one interfaces with it than books are. And maybe a poem read aloud is more visceral, more directly involving the senses, than one that simply appears on the page, but only on a superficial level. The question is whether one's internal understanding of a poem, how they interface with it, produces a visceral effect. But I haven't heard yet, no pun intended, how poetry can produce the same effect one feels from hearing an extremely abrasive piece of music, which physically engages one regardless of any emotional or intellectual content it might have.
