If I can quote myself, I explained whatever it is I'm doing once for No Tell Motel, and I still think it's the clearest I've ever been about this: "I don't write free verse poems - mostly because I can't. But I am interested in the musical effects achievable with free verse."
Shane McCraeI believe rhythmic sensibility is always a product and extension of language, defined broadly, among other things. But it is an immediate product and extension - no time elapses between the exposure to language and the creation of rhythmic sensibility.
Shane McCraeI love to read long books. I enjoy experiencing that extension. But it's not something I feel comfortable with and not something I think I can gain comfort with by practice. It was a real struggle for me while writing memoir to get past three pages or so. In poems, I can write long poems. But length in prose: no.
