432 Hz is the natural "keynote" in the universe, as opposed to 440 Hz, which is the standard in the music nowadays. 432hz vibrates on the principals of the golden mean PHI and unifies the properties of light, time, space, matter, gravity and magnetism with biology, the DNA code and consciousness. 432hz Natural Tuning has profound effects on consciousness and also on the cellular level of our bodies. By retuning musical instruments and using concert pitch at 432 hertz instead of 440 hertz, your atoms and DNA starts to resonate in harmony with the PHI spiral of nature. 440hz concert pitch is centered in the mind whereas 432hz concert pitch is centered in the heart. Most music worldwide has been tuned to 440 hertz since the International Standards Organization (ISO) endorsed it in 1953, following the prior recommendations of the Nazi party spoksman, Joseph Goebbels in 1939.
