I teach writing. I have read a lot of books about prosody but this is the one you want if you are interested in a full description of what a poem requires. By that I mean the full soundscape of this particular use of language and aesthetics. Karl Shapiro is the other author and contributed mightily but know this: there isn't any better introduction to the craft that fully rates the different contributions of sound and color and image than this. It is also beautifully written which is not necessarily what one can expect in a book on poetry. I will be using this as a handbook, wearing its pages well ( )
