For centuries, people have used music and sound to promote well-being. Walker^[1] credits Roland Hunt, who pioneered the use of combined music and light to treat individuals suffering from neurotic and mental illnesses in the early twentieth century.

As a death-related counselor in Florida, USA, Helen Baker,^[2] a light therapist, works with individuals experiencing grief. She combines music and light in her counseling sessions for the bereaved. She states that light waves, represented by colors, correspond to the tonal frequencies of sound; additionally, utilizing light and sound as pure vibrations holds significant potential in psychotherapy, physical healing, and transforming personal and cultural consciousness. Baker believes that using music and light helps individuals who are troubled process their grief or recover from challenging diagnoses. However, this field has yet to be fully explored. Baker connects the seven colors of the spectrum to the seven tones on the diatonic scale and then to the seven major glands in the physical body. She explains that the body acts as a receiving station for energy. When incoming vibrations align with the corresponding frequency of a body part, they resonate with it. Conversely, when this alignment is absent, disharmony occurs. When intense, non-productive thoughts or emotions are present, as experienced by a bereaved person, vibrations struggle to flow freely throughout the body, causing blockages. Disease results when the vibrational activity of a specific organ deviates from its normal state, either due to blockage or overstimulation.

Halpen & Savary^[3] present a system for correlating the spectral colors and tones of the major musical scale. They state that the effects of combined colors and tones are remarkable. Listeners will calm down from excitement when overly stimulated individuals are shown colors while music based on the corresponding keynotes is played. They experience states of relaxation and physiological balance that are not typical. Their breathing becomes deeper and more regular. Their pulse slows, and the hemispheres of their brains become synchronized.

Sir Isaac Newton^[4] made several observations about light in the early eighteenth century. In one observation, he concludes that the seven colors of light (red, orange, yellow, green, blue, indigo, and violet) correspond to the seven musical tones or intervals of the eight tones (sol, la, fa, sol, la, mi, fa, and sol).

Anderson^[5] suggests that seven colors correspond with the seven chakras and the musical scale. Her correlation of tones and colors is as follows: D flat = red, D = blue, E flat = green, E = deep red, F sharp = yellow, F = purple, G sharp = silver, G = black, A sharp = gold, A = blue, C = brown, B = violet.

Retallack^[6] presents a combination of tones and colors. In her system, she assigns A as red-orange, B as yellow, C as yellow-green, D as green-blue, E as blue-violet, F as violet, and G as deep red.

Ghadiali introduces another blend of tones and colors. He bases his correlations on the equivalence of the fundamental sound frequency to each color. For example, he states that the fundamental frequency for his Spectro-Chrome red is 436,803,079,680,000 cycles per second. To bring this frequency into the audible range, he divides it by 2, forty times. In other words, Ghadiali shifts the tone’s frequency by 40 octaves. This calculation results in a sound frequency for red of 397.27 Hz. Ghadiali claims this frequency is the closest to the tone G (g’ in the one-line octave).^[7]

The musician and acupuncturist Fabian Maman, along with biologist Helene Grimal, introduced sound therapy at the Cancer Help Centre in Bristol, England. This treatment originated in ancient Japan and has been practiced there for centuries. Maman and Grimal worked with cancer patients at the center, observing the effects of their treatment.

Maman experimented with using specific sound frequencies instead of needles when treating patients with acupuncture. He discovered that the results were equally effective, which encouraged him to pursue scientific experiments. Along with Grimal, he studied the effects of sound on blood cells under a microscope. They captured images of the cells using Kirlian photography while playing notes from the chromatic scale. To their surprise, the photographs revealed color flowing into the blood cells when they played a specific musical note. They observed that the shape of the cells changed in response to the note being played. Maman and Grimal concluded that there was a direct link between the cells’ form and color, their biofield strength, and the frequency of the note. They also found that these effects could be reproduced, though never exactly, suggesting each living cell has its unique quality.

Reproduction results depended on several factors, including the vitality and condition of the individual whose blood cells were examined. For example, when they experimented with blood cells from cancer patients, they obtained different results compared to those without cancer. In these patients, systematic disorganization of cellular material was observed as they progressed up the scale until they reached between a’ (440Hz) and b’ (494Hz), when the cells frequently exploded.^[8]

Sound frequencies can be used with the same results as light to restore an individual’s health.^[2][3] These low “beat frequencies” have the same therapeutic effects as light.^[9] When one or more selected sound vibrations are directed onto a person’s body, they trigger reactions within the body’s cells, thereby destroying diseased blood cells.^[8]

Using Kirlian technology, Indian researcher J. M. Shah captured images of the electromagnetic energy glow surrounding the human body. He found that the disease first appears in the aura before transferring to the physical body. The illness can reach the physical body in six to eight months. Therefore, he concluded that color therapy could be used preventively.^[10]
