There is a lot of information on the internet about the solfeggio scale and tuning forks. Hopefully this will help to clarify some misconceptions about these frequencies and offer some suggestions on how they can used.
Origin of the Solfeggio Frequencies
Solfeggio is a derivative of the word solfege. The dictionary meaning solfeggi is the study of singing and musicianship using solemnization. Solemnization is the assigning of a note of a musical scale with a syllable (do, re, mi...etc.). So there is nothing mystical about the term solfeggio and the term is not specific to the solfeggio frequencies associated with tuning forks. Take a musical scale, assign syllables to it, call it a solfeggio and you would not be wrong.
The solfeggio scale commonly used for healing purposes was brought to our attention in the book The Healing Codes of the Biological Apocalypse by Leonard Horowitz and Dr. Joseph Puleo. The sections of this book from Dr. Puleo contain some excellent information on healing and is recommended reading. The rest of the book (about 2/3) is about the history of the solfeggio scale and reads like conspiracy theory; Knights Templar, Masons etc. I say this not to dissuade you from buying the book, only so that you know what you are spending your money on.
There are many things being said about the solfeggio set with the most interesting being the claim about how one of the frequencies, 528hz, can repair DNA. At the time I am writing this paper, I am not aware of anyone who has come forward to say that they are repairing DNA with 528hz. What I have heard is that someone is using the 528hz to create clustered water.
Clustered Water vs Bound Water
In simple terms, when water molecules are bound together in clumps, it is called bound water. Water which is broken down in small stable rings or clusters is called clustered water. Clustered water is smaller in size than bound water which is the key to its health benefits. Our DNA, cells etc. have membranes that allow water to flow through it. As water flows through our cells, it clears impurities. Because clustered water is smaller, it flows more easily through cell membranes and is more efficient in removing those impurities. The larger, bound water does not flow easily through cell membranes and therefore, the impurities remain. Left long enough, these impurities can eventually result in illness.
If the 528hz does cause water to become clustered, then claiming that this frequency "repairs DNA" is still a bit of a reach. What they should really be saying is that the 528hz may help to remove impurities allowing our body to become and remain healthy and balanced.
