Psychoacoustic Vibrations and expanding our awareness
Psychoacoustics is essentially the study or application of the perception of sound on the nervous system.
Within the Domain of Psychoacoustics, music, sound, Frequency, and vibration, are all essentially interchangeable, because they are different approximations of the same essence.
Now lets consider sound and its effect on the nervous system. Hearing is the first sense we develop in the womb. Sound touches us and influences our emotions like no other source of input or expression. It is a frequency of vibration seeking to express itself through all of us.
