It is a device going through the motions, using a measured process, to
attain harmony (or curb dischord). A scientific instrument slowly drips
water into a glass, which periodically spins to be "played"
by a cork-tipped player arm. Concurrently, a small hammer strikes a tuning
fork, indicating the aural goal. Again and again, as the glass fills with
water, it alters its pitch, closer to that of the tuning fork. Its struggle
is in the attempt to attain perfect pitch, though once attained, is fleeting.
