Wallace Stevens' "The Man With the Blue Guitar" (http://www.geegaw.com/stories/the_man_with_the_blue_guitar.shtml) came to mind. It's by no means short, but maybe a quote from it? It's awesome. And I definitely recommend it regardless :)

and this isn't a poem, but that amazing Picasso painting... (http://www.physics.miami.edu/~chris/art/picasso/old_plyr.jpg) I have a postcard of it.

your post made me happy.
