The name “Solfeggio” – and the note syllables Ut, Re, etc. – comes from Solfège, a traditional way of naming the tones – primarily of the C major scale or any major scale Kodaly Method -, especially in teaching singers. The healing powers attributed to “Solfeggio frequencies” or “Ancient Solfeggio” should not be confused with Solfège.[edit]The Frequencies

The Solfeggio frequencies include:01 = 174 Hz02 = 285 HzUt = 396 HzRe = 417 HzMi = 528 HzFa = 639 HzSol = 741 HzLa = 852 Hz09 = 963 HzThe numerical values of the Solfeggio Frequences are generated by starting with the vector 1, 7, 4 and adding the vector 1, 1, 1 MOD 9. Each higher frequency is found by adding 1, 1, 1 MOD 9 to the previous lower frequency.

The final frequency, when 1, 1, 1 is added to is, returns the frequency to the lowest tone 1, 7, 4.Ut = 396 Hz which reduces to 9 [reducing numbers: 3+9 = 12 = 1 + 2 = 3 ; 3+ 6 = 9]Re = 417 Hz which reduces to 3Mi = 528 Hz which reduces to 6Fa = 639 Hz which reduces to 9Sol = 741 Hz which reduces to 3La = 852 Hz which reduces to 6[edit]The BeliefThe frequency assigned to Mi for “Miracles”, 528 Hz, is said by proponents of the idea to be the exact frequency used by genetic engineers throughout the world to repair DNA.[citation needed][2]

The “Solfeggio frequencies” are cyclic variation of the numbers 369, 147 and 258.[3]It is claimed that each frequency has specific spiritual and physical healing properties. It is also claimed that they are part of a process that can assist you in creating the possibility of life without stress, illness, and sickness.[4]
