The poet misspoke: there is no lone
cicada singing to himself;
each is a multitude.
But we may ask
whether he hears
his own voice, or the multitude,
or anything he might be said to recognize.
And we learn that like Odysseus
his auditory organs must be damped
to save him from
in this case, his own deafening decibels,
trembling in the wave
in which tries
to sing loudest,
to sing loudest,
to be heard alone
in that surging song
in that surging song
that comes to us as
one great rustling roar.
The female does not sing
but waits on the leafy shore
of an ocean of resonant systems
contracting and
releasing
their tymbals, in no real order,
deep in the pulse of mating.
Tymbals, we learn, are membranes
that resound within
the living husk
attached to apodemes
(stronger, stiffer than our vertebrate tendons
but like them, storing elastic energy)
that buckle inward in sequence
posterior to anterior,
each inward pull yielding a train of pulses,
the outward buckling, the release, just one;
the waveform starts
with an inward-going rarefaction
(that is, a thinning out of air)
followed by outward compression,
then decay,
approximately exponential.
After the first pulse, if the next
come quickly
it finds itself beginning
on the inward-going
half-cycle
of the one before,
so pulse on pulse
become
coherent waveform.
But coherence is
lost
if the preceding pulse decays
below a tenth of its peak amplitude.
if the preceding pulse decays
below a tenth of its peak amplitude.
A difficult
singing.
Each cicada among
the thousands,
ears sealed, just
pulls in, lets go
pulls in, lets go,
fifty times a
second, more,
wakened only by the
wing flicks
of the attracted female, silent but visible
as she flutters in the shadowy trees,
beckoning that one that seems to her
loudest, or most coherent,
among the rustling mass:
the one, the irresistible one.
