Solfeggio frequencies are a myth, probably originated in the late 1990s

And much more: find out yourself

 

More information (translated from the german website "Wissen Datenbank 256 HZ 432 HZ")

An important criterion in the definition of the Solfeggio frequencies is that all their base values ​​and octave values ​​in the Theosophical Reduction, always the "Digital Root" known by Tesla (sums) 3, 6 or 9 result.
In his work, Nikola Tesla repeatedly pointed out the importance of these three numbers as fundamental indicators of the divine and the creative power. He also pointed to the energetic ordering of our physically describable world.

Regarding the names of the frequencies, I must point out that they are not authentic names, Leonard Horowitz have found their way into the world of frequencies. Since 1999, however, they have developed into their own reality independent of Mr Horowitz.

And here comes an important fact:
Why is the frequency 336 HZ not a solfeggio frequency? Or did I discover one now?

I quote from the Bach flower portal:

After the documents presented in "Healing Codes for the Biological Apocalypse," Dr. Joseph Puleo knew the Pythagorean method of numerical reduction and discovered the pattern of six repeating codes.
The Pythagorean method is a simple reduction method that converts large numbers into single digits by adding the values ​​of all digits of the number. If, after the first addition, the number still contains more than one digit, the process is repeated, e.g. can be reduced 456 to 4 + 5 + 6 = 15 and then reduced to 1 + 5 = 6. Thus, the number 456 finally decreases to the single digit 6. Following this pattern, Puleo discovered that the Solfeggio frequencies are based on this mathematical reduction and can all be reduced to the checksums 3, 6 and 9 ...

That's the same with the frequency 336 HZ (21 HZ). Or what about the frequency 504 HZ (63 HZ)? Or the frequency 648 HZ (81)? No solfeggios? Did Puleo miss that?

Find new solfeggio frequencies yourself and try the effects!
The principle is simple: they always have to think in terms of reference frequencies. Go through all the odd, whole, natural numbers. If you encounter a number that gives 3 or 6 or 9 in the checksum, you have found a Solfeggio frequency! 111 HZ is a nice Solfeggio frequency.
