These tone frequencies were supposedly a set of six notes of an ancient musical scale used in Sanskrit and Gregorian Chants, rediscovered by Dr. Joseph Puleo as described by Dr. Leonard Horowitz in his book “Healing Codes for the Biological Apocalypse”

Ut (Do) = 396Hz

Re = 417Hz

Mi = 528Hz

Fa = 639Hz

Sol = 741Hz

La = 852Hz

Those names were taken from the first syllables of the hymn to St. John the Baptist:

Utqueant laxis

Resonare fibris

Mira gestorum

Famuli tuorum

Solve polluti

Labii reatum Sancte Iohannes (Later on became note Si)

As suggested by its lyrics, each phrase has a mystic meaning, that is also related to its sound (frequency):

Ut = 396Hz - Liberation from Guilt and Fear

Re = 417Hz - Change, Transmutation, Moving On From Past Beliefs, Undoing Situations

Mi = 528Hz - Miracle and Transformation (DNA Repair)

Fa = 639Hz - Relationships and connection with people

Sol = 741Hz - Intuition, Consciousness Expansion, Awakening

La = 852Hz - Spiritual Reconnection

Those frequencies are also reduced to the numbers 9-3-6, which suggests a connection to the Holy Trinity.

Each frequency has a specific spiritual and physical healing properties, and were believed to bring great spiritual blessings when sung in harmony with the masses during religious cults.

There is also the extended 9-tone Solfeggio Scale that will include 174 Hz, 285 Hz, 963 Hz - resolving the 9-3-6 numeric cycle.
