Solfeggio frequencies are a set of tones brought to public attention by Dr. Joseph Puleo and Dr. Leonard Horowitz in their book Healing Codes for the Biological Apocalypse.

Their claim is that the frequencies can be derived from the Hebrew Bible, namely the book of Numbers.

These frequencies are also claimed to make up the ancient 6-tone scale thought to have been used in sacred music, including the Gregorian Chants.

Other researchers have done their best to debunk these claims, and Subtle Energy Sciences founder Eric Thompson was initially skeptical of the claims made of the Solfeggio Frequencies on many websites.

But after converting the Solfeggio Frequencies to silent scalar wave signatures and amplifying them thousands of times, he found that each of these frequencies did indeed exert positive effects in the mind and body.

So, although we aren’t sure whether or not the history attributed to the Solfeggio Frequencies is accurate, we can definitely confirm that the Solfeggio Frequencies each possess unique vibrational qualities that positively influence the human mind and body, especially when converted to scalar energy and amplified thousands of times.

Furthermore, researcher John Hutchinson once used tones within the range of the Solfeggio Frequencies to clean up oil pollution in the ocean, and these results were corroborated by the Analytical Chemical Testing Laboratory, Inc. of Mobile, Alabama.

Puleo and Horowtiz originally designated six Solfreggio frequencies: 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz and 852 Hz. But Horowitz later added three additional frequencies: 174 Hz, 285 Hz and 963 Hz.

These nine frequencies form what Horowitz refers to as “The Perfect Circle of Sound”.

Each Solfeggio Frequency is created using a waveform that conforms to the Golden Proportion, meaning that the amplitude to wavelength proportion is 1: 1.618.

(Normally, audio waveforms produced by most tone generators feature a 1:1 amplitude to wavelength ratio.)

Having integrated the Golden Proportion waveform into each Solfeggio frequency, the frequency remains the same, but the energetic quality it produces is deeply balanced.

Scalar Wave Transduction

After each Solfeggio Frequency is created using Golden Proportion waveforms, it is then played through a transducer that converts the audible sound frequency into an inaudible scalar wave signature.

Scalar energy is a nonlinear, non-Hertizian, Zero Point energy capable of carrying any information with which it interfaces.

Although it is entirely silent, its effects are quite tangible and therapeutic.

Energetic Encoding Process

  • In the Silent Solfeggio Series, the pure vibration and positive effects of the Solfeggio frequencies are amplified many times more than the conventional, audible tones without the amplified sound/irritation/distortion that would otherwise occur if you were to increase the volume (and effects) of the audible tones.
  • As a consequence of this silent scalar amplification, you will notice results much more quickly and much more powerfully than with the conventional Solfeggio tones.
  • The Silent Solfeggio Series can be combined seamlessly with your favorite music, even rock music, for powerful results. This is difficult, if not impossible, to do with the conventional, audible Solfeggio tones.
  • Silent Solfeggio is completely silent, so you can enjoy the benefits of these frequencies in ways not normally possible with tones.
  • You can combine multiple frequencies together without clashing (which is another benefit of having the Solfeggio frequencies as silent, amplified scalar waveforms).
  • You can amplify the vibration—and positive benefits—of the frequencies in a way that is not possible with audible tones.
  • No headphones (or sound) required.
  • Take the silent scalar frequencies with you anywhere, anytime. No need to worry about sound or headphones. Just set it and put it in your pocket and benefit from the frequencies as you go about your day.

Enjoy the Silent Solfeggio scalar frequencies by themselves or combine them with audible Solfeggio frequencies to elevate them to an all new level.

Nine Solfeggio Frequencies (as Silent Scalar Wave Forms)

Plus Two Bonuses!

174 Hz

The lowest of the tones has been reported to provide pain relief for some issues as well as general organ support.


285 Hz

Reported by some to aid repair of damaged organs. A great-feeling silent scalar frequency that makes your body feel really good.


396 Hz

Turning grief into joy, liberating guilt & fear

Very relaxing and peaceful. Wonderful for meditation.


417 Hz

Undoing situations and facilitating change

Supports inspiration, creativity, enhanced productivity, and overcoming procrastination and lethargy.


528 Hz

Transformation and miracles (DNA repair)

Stimulates the heart chakra. Has been reported to help restore sound, peaceful sleep (when used at low amplitude).


639 Hz

Re-connecting and balancing, relationships

Fosters forgiveness, peace and love in relationships. Stimulates the higher heart chakra.


741 Hz

Solving problems, expressions/solutions

Reported by some to aid body detoxification, better eating choices and self-expression.


852 Hz

Awakening intuition, returning to spiritual order

Reported to help heighten spiritual awareness and discernment.


963 Hz

We’ve received reports of this being a powerful aid to meditation and spiritual awareness. Stimulates the crown chakra.


BONUS: Solfeggio Six

Combines the six original Solfeggio Frequencies (as silent, amplified scalar wave forms) into one integrated wave form: 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz.


BONUS: Solfeggio Nine

Combines all nine Solfeggio Frequencies (as silent, amplified scalar wave forms) into one integrated wave form: 174 Hz, 285 Hz, 396 Hz, 417 Hz, 528 Hz, 639 Hz, 741 Hz, 852 Hz, 963 Hz.


Using a proprietary process, the resulting scalar wave signature of each Solfeggio Frequency is then digitally captured, amplified thousands of times and encoded into its own dedicated mandala picture file and silent audio file.

When the energetically encoded picture file or silent audio file is opened/played on a computer, tablet, phone or mp3 player, it emits the amplified scalar-wave signature of that Solfeggio Frequency through your electronic device.

No sound required.
