Among teachers and critics and in the community of writers, we need more advocates for attunement to the sonic properties of prose. Joe Moran's recent essay on sentence-making consoles me (and probably also the underrated writers I most admire). I immediately printed it out for use with my creative writing students. Here's a prime passage, but follow the link at the end to read the whole.
"When the writer has a tin ear for the sound of a sentence then the reader knows, just as when she hears flat or pitchy singing, that something is wrong, even if she can’t quite say why.
I can let a book fall open and tell, just from reading a few sentences, if I will like it. However compelling the subject of a book might be, I find it hard to carry on reading if its sentences are boring. I should be more forgiving, since I have written my share of boring sentences. I am not. Neither are you, even if you don’t know it yet. You think you are looking past this sentence into what it is saying—about life, love, the existence of angels, the design of the injection-molded polypropylene stacking chair, whatever it is— but no. You think you care what this is about, but really you care how it sounds. You are reading it for its sentences."
