Solfeggio Frequencies

I first heard of the Solfeggio Frequencies when someone sent me a link to Forgotten In Time: The Ancient Solfeggio Frequencies, an article connecting certain healing properties to specific frequencies. I eventually read Healing Codes for the Biological Apocalypse, the book by Leonard Horowitz that first brought the world’s attention to these “special” frequencies and I created an album to test these frequencies myself: the process was rewarding and I appreciate the strong (and enduring) response to the work.

As an artist I value mystery and I accept that there are some experiences that cannot be quantified by data, but as someone with a deeply skeptical world view, I’m leery of anecdotal evidence. And there is the root of my problem: evidence. There is no scientific evidence — none of which I’m aware — supporting the effectiveness of the Solfeggio Frequencies. The “powers” attributed to Solfeggio Frequencies defy credibility, yet when listeners relate to me inspiring stories of spontaneous healing and transformation, my doubt inevitably shifts. Anyway, I’m intent on neither proving nor disproving these frequencies, simply to explain them as I understand them.

What Are The Solfeggio Frequencies?

Rather than sounding subjectively harmonically pleasing, the six tones that constitute the Solfeggio frequencies are based on shared mathematical properties and a connection to the Latin hymn Ut queant laxis, also known as The Hymn of John The Baptist. In his book Healing Codes for the Biological Apocalypse, author Leonard Horowitz says that it was “revealed” to him that certain syllables in this hymn relate to specific pitches and these pitches, or frequencies, each have an associated healing quality.

An image surfaced a few years after the book was first published. The image is a regular enneagram (a nine-sided star polygon) with the solfeggio frequencies written at the points. In order to make this image work, three additional points must be plotted, and while the math checks out, it no longer jives with the “original” tone set.

The Solfeggio Frequencies

174 Hz – ??
285 Hz – ??
396 Hz – UT – Liberating Guilt and Fear
417 Hz – RE – Undoing Situations and Facilitating Change
528 Hz – MI – Transformation and Miracles (DNA Repair)
639 Hz – FA – Connecting/Relationships
741 Hz – SOL – Awakening Intuition
852 Hz – LA – Returning to Spiritual Order
963 Hz – ??

Not only is the attribution of these special properties to each of the Solfeggio Frequencies dubious, but historically it’s challenging (but not impossible) to accurately reproduce without modern tools, which calls into question the “ancient” nature of these frequencies. Anyway, whatever reservations I may have had never prevented me from trying the Solfeggio Frequencies myself. I’ve used Solfeggio Frequencies on a number of projects: Deltadream (396 Hz), Hibernation (417 Hz), Aurora (528 Hz) are each based on a single Solfeggio Frequency while Solfeggio Suite and Solfeggio Cycle feature all Solfeggio Frequencies.

Musical Notes of the Solfeggio Frequencies

It must be said that, as a scale, the Solfeggio Frequencies sound terrible. The notes cover more than an octave and are not harmonic and sound unpleasant. Here are the Solfeggio Frequencies as they relate to nearest musical notes:

396 Hz – G4
417 Hz – G#4
528 Hz – C5
639 Hz – Eb5 ~ E5
741 Hz – F#5
852 Hz – Ab5 ~ A5

As you can see, two of the frequencies — 639 Hz and 852 Hz — are so far from any note in the Western Temperament that I can’t even guess which note they most resemble: they’re half-tones, existing as notes between notes.
