Sound waves are vibrations felt by the ear. Vibrations are
oscillating waves. Sound waves exhibit transverse wave qualities.
The Pythagoreans spoke of the creative nature of sound waves when
they taught that everything in existence has a voice which
continually sings the praises of the Creator. They taught that
mankind would become in tune to the music of the spheres, which
is to say, we will vibrate at the same frequency (sidereal harmonics;
the standing wave is an essential ingredient of harmonics), when
liberated from the bondage of our material bodies here in the lower
world. In The Bible, as we receive eternal life, we partake of this
harmonic nature, referred to as eternally singing hymns of praise to God.

Joh 1:1 In the beginning was the Word, and the Word was with God, and the Word was God.
