When an opera singer vibrates a glass with their voice, they
have matched the resonant frequency of the glass. As the singer increases
the volume of their sound, the resonance becomes too great for the
forces that hold the glass together and it shatters. Modern medicine
now uses sound waves to break up kidney stones and gallstones.
Every organ, bone, and cell in the body has its own
resonant frequency. Together they make up a composite frequency like
the instruments of an orchestra. When one organ in the body is out
of tune it will affect the whole body. Through sound healing it may
be possible to bring the diseased organ into harmony with the rest
of the body, hence avoiding the need for drugs or surgery.
The principle of entrainment states that powerful vibrations
from one source will cause less powerful vibrations of another source
to lock into the vibration of the first. Nature always seeks the most
efficient state; it takes less energy to pulse
in co-operation that in opposition.
Scientific Research into Sound
In the 18th century, Ernest Chladni, a German physicist, found
that when a violin bow was drawn vertically across the rim of a metal
plate the sound waves produced created patterns
