Anselm Berrigan has two Harriet posts (here and here) that present a letter from his late stepfather, the British poet and novelist Douglas Oliver. The letter nutshells Oliver’s analysis of the profound relationship between prosody and voicing in poetry and how that relationship affects each reader’s understanding of a given poem.
I had attempted to get at something like this many years ago in a very rudimentary essay, but I had—and still have—neither the training nor the temperament, nor (needless to say) the insight, to do what Oliver does in his all too brief letter. The letter condenses ideas presented in his 1989 book Poetry and Narrative in Performance, which unfortunately is out of print, so I hope to track it down through my local library.
In any case, I highly recommend Berrigan’s posts.
