[Decided to take this out of the wee comment box & post it here:]
I would like to add, that all this is not to say that there isn't musicality & performative strangeness in free verse & prose poetry, too.
But there is something ancient, powerful & uncanny in a line of verse. "The lion sleeps on its paws./It can kill a man." Prose poetry & all the music of poetry stems historically from verse measure itself, the limping foot of Dionysius.
