Note from Iris

The History of the Solfeggio Tones begins with King David, in the Bible, who was given four tones which he used to create the Psalms on his lyre.  David passed these secret tones to his son King Solomon. Solomon used the tones in the creation of the Song of Songs, considered the most sacred of psalms. Sometime after Solomon, the tones were lost. 

During the creation of the ancient Gregorian Chants, such as the great hymn to St. John the Baptist, five Solfeggio tones were rediscovered.  Later, a sixth note was added based on the discoveries of Pythagoras and his harmony of the spheres. These were also lost. 

In the 1990’s, Dr. Joseph Puleo, a naturopathic physician in northern Idaho was given the secret of the psalms.  They first appeared on his windshield while he was driving with his wife, Linda, although she was unable to see them.  Later more details were given to him in appearances by Jesus and an Angel.  The story is presented in the book
Healing Codes for the Biological Apocalypse, by Dr. Leonard Horowitz and Dr. Joseph Puleo, available free on kindle.  I met Drs. Puleo and Horowitz in 2000 and ended up moving to Idaho to work with Dr. Puleo and have been here ever since.

Joey and I were  research partners and buddies. He was completely unpretentious and had a wonderful earthy sense of humor. He was and excellent cook and loved to have guest over for dinner parties. Click here for Dr. Horowitz’s interview that led to the extraordinary meeting with 
Dr. Puleo.

After the turn of the millennium, Joseph Crane (book:
On the Wings of Heaven, with GW Hardin) was told in an appearance of Archangel Michael that two Solfeggio scales existed – one profane and one sacred.  The sacred has been known as the “Secret Solfeggio.”  Later, Archangel Michael gave Joe Crane six of the frequencies to be used for healing.  Subsequently, he told Joe that a subset of the frequencies existed, called the Divine Masculine frequencies.  I met Joe Crane and Gary Hardin in 2007. We all attended the 2008 life-changing Eden Event in Yellow Stone National Park where I met Grammy Award winning musician, Barry Goldstein.  Amazing phenomenon appeared in photographs, above and around us although it was pitch dark outside:  For info CLICK HERE. (Look under “Past Eden Event Pictures, 2008”)

In 2009, through the guidance of Archangel Gabriel, Gary W Hardin (books:
The Messengers; On the Wings of Heaven) broke the code of both Solfeggios which were shown to be linked together. Gary W. Hardin, who is a mathematician and NY Times best-selling author, and Grammy winner Barry Goldstein have worked on the Solfeggio tones together. See Gary’s  website video for more information regarding the Eden Events and the Solfeggios. For information on Barry Goldstein, CLICK HERE.

During the process, yet a third set of Solfeggio frequencies came about in Gary’s mathematics. The third set consists of the sum of the first two sets.  Additionally, an entire fractal system of Solfeggios that affect specific parts of the body 
appeared. GW’s calculations produced three levels to the Grand Solfeggio tones:  the Archetypal (earthly), the Divine (heavenly), and the Universal (cosmic). Within each level there are two components, the Masculine and the Feminine.  When all the tones of a component are played, they create a harmonic of Unity and Oneness. For more information, visit GW Hardin’s website.

About this time, over a two day period, as I was working on the Grand Solfeggio CD, the affirmation to be used with the Solfeggios was given to me by Archangel Michael: 
I CHOOSE TO BE WHOLE AND COMPLETE IN GOD’S DIVINE IMAGE,”.  Because we have free will, we must consciously affirm our desire. The Solfeggio Tones have been lost to the world for a very long time, but now the Angels and Ascended Masters have returned them to humanity.  These tones can be used in healing and creating music. As we look at the six original Solfeggio frequencies using the Pythagorean Skein, we find the base vibrational numbers are 9, 3, 6, 9, 3, 6.  Nikola Tesla has told us, “If you only knew the magnificence of the 3, 6, and 9, then you would have the key to the universe.”

Many Blessings,

Cymatics is the study of the effects of sound on matter. It was coined by Dr. Hans Jenny (1904-1972). For 14 years he conducted experiments animating inert powders and liquids into life-like flowing forms, which mirrored patterns throughout nature, art and architecture.  All of these patterns were created using simple tones within the audible range.   

Typically, the surface of a membrane is sprinkled with a powder and vibrated with a tone and different patterns emerge depending on the frequency.  What you see on the membrane is a repeatable physical representation of vibration, or how sound manifests into form. Based on these experiments, we can see that sound can change the shape of matter.
