Metrognome

of hands pausing
hovering above]
the tips of fingers
the arch and whorl
pad callus capillarian beating]
the encompassing round palms
hoarding of sound]
of wooden boards planed for
resonance, wires taut and twisted
too wound about to quiver]
the ordered rank of keys
as yet unplayed]
every
knuckle 
angle 
precise]

an 
ex]
halation
