Solfeggio Frequencies

I first heard of the Solfeggio Frequencies about ten years ago when I read Forgotten In Time: The Ancient Solfeggio Frequencies, an article so strangely specific that I thought I would create some music based on these frequencies. And for the record, I’ve found the process to be rewarding and I appreciate the enduring (and strong!) response to the work.

As someone with a deeply skeptical world view, I’m leery of anecdotal evidence; but as an artist, I believe in mystery and I accept the that there are some experiences that cannot be quantified by data. Maintaining the balance between these two perspectives is sometimes tricky, especially in an era of fact checking, fake news, and truthiness.

And therein lies the fly in the ointment: there is no scientific evidence — none that I’m aware of, anyway — supporting the effectiveness of the Solfeggio Frequencies. Nevertheless, listeners relate to me the most inspiring stories of healing and transformation that I can only marvel at the apparent miracle of it. I don’t know what’s a work here: maybe soothing music facilitates healing, maybe binaural beats are helping relax, maybe it’s a placebo effect, or maybe all of these factors combine to reinforce the benefits of medical treatment. Whatever. One thing of which I’m certain is that the Solfeggio Frequencies defy credibility, even though listeners who engage with my music tell me of profound experiences they had while listening to them. I’m willing to have it both ways.

What Are The Solfeggio Frequencies?


The Solfeggio frequencies are a 6-tone musical scale. The syllables used to sing this scale are derived from 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 each syllable in this scale relates to a specific pitch and these pitches, or frequencies, each have an associated healing quality.

The Solfeggio Frequencies

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

Not only are the healing qualities listed above vague and unspecific, but the origin of the Solfeggio Frequencies is wrong: the syllables are ancient, yes, but the manner in which these frequencies were “revealed” to Horowitz is dubious. Mysticism aside, the tools required to accurately measure frequency are modern innovations: I am curious how “the ancients” identified and reproduced these frequencies so reliably. Anyway, if I were to guess where the revelation came from, I would guess that Kabbala was somehow involved, if only because Kabbala has a strong mathematical component. Also, Kabbala is something about which I know nothing.

None of my reservations prevents me from trying the Solfeggio Frequencies myself, of course. 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 almost in the middle, the notes between the notes.
