Analysis of The Sounds Between the Silence

Does silence exist
amid those exposed moments
where you are led to believe
nothing exists
just utter silence.
I doubt it is true
for what is sound
but a frequency that vibrates
so does this planet
have a veritable hum
what an orchestra the Milky Way
must be.
Even Pierre Boulez
composed with the gaps
or silence
that existed between notes
as being important
yet he filled them with
ethereal nuances.
Maybe the great cosmos
is never still
just masked
by our own self will,
those background compositions
within the cosmos
are the sounds of silence
albeit vibrations of life
that never ends.
