Tune
--Kay Ryan 

Imagine a sea
of ultramarine
suspending a
million jellyfish
as soft as moons.
Imagine the
interlocking uninsistent
tunes of drifting things.
This is the deep machine
that powers the lamps
of dreams and accounts
for their bluish tint.
How can something
so grand and serene
vanish again and again
without a hint?
