Most people read poetry listening for echoes because the echoes are familiar to them. They wade through it the way a boy wades through water, feeling with his toes for the bottom: The echoes are the bottom. ↗
I work very hard on all my poems, but most of the work consists of trying not to sound as if I had worked. I try to make them sound as natural as possible, but within a quite strict form, which to my ears has a lot to do with musical rhythm and sound. ↗
