The concept of Solfeggio frequencies originates from a system of musical tuning known as “just intonation,” which is a method of tuning musical instruments to match certain mathematical ratios found in nature. The six-tone scale we know as the “Solfeggio frequencies” was first introduced by Guido of Arezzo (991 AD – 1050 AD), a Benedictine monk. He used the scale to teach melodies and harmonies for singing hymns.
The specific set of frequencies referred to as the Solfeggio frequencies wasn’t “discovered” in the usual sense of the word. They came back into public awareness through Dr. Joseph Puleo, a naturopathic physician and one of the world’s leading herbalists, who began exploring the Solfeggio in the 1970s. His exploration began with a vision of the Biblical numbers mentioned in the Book of Numbers, Chapter 7, verses 12 through 83.
According to Puleo’s account, he was guided to apply Pythagorean reduction to these verse numbers, which resulted in a series of six electromagnetic sound frequencies which he identified as Solfeggio frequencies. He and Dr. Leonard Horowitz, a public health authority, later published these findings in the book, “Healing Codes for the Biological Apocalypse,” claiming the frequencies could be used for healing.
