eye and ear:

When Beethoven’s ear
was shut to the vomittings
of our sky, his soul
soared higher than any
flamingo could ever wish
to fly. How high, how far
yearns the windscreen wiper
of the eye when Fate grumbles
with a sausaged sound. What
causes ducks to gaggle,
hounds to hound? Only the sight
of see my friend, the sight
of sea and sound.
