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 with 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 sound’s tonal frequencies; additionally, using light and sound as pure vibrations holds significant potential for psychotherapy, physical healing, and transforming personal and cultural consciousness. Baker believes that music and light help troubled individuals process grief or recover from challenging diagnoses. However, this field remains underexplored. Baker connects the seven colors of the spectrum to the seven tones of the diatonic scale, and then to the seven major glands in the body. She explains that the body acts as a receiving station for energy. When incoming vibrations align with a body part’s corresponding frequency, they resonate with it. Conversely, when this alignment is absent, disharmony occurs. When intense, unproductive thoughts or emotions are present, as experienced by a bereaved person, vibrations struggle to flow freely throughout the body, leading to blockages. Disease results when a specific organ’s vibrational activity 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 note that the combined effects of color and tone are remarkable. When overly stimulated individuals are shown colors while music in the corresponding key is played, listeners calm down from excitement. They experience states of relaxation and physiological balance that are not typical. Their breathing becomes deeper and more regular. Their pulse slows, and their brain hemispheres become synchronized.

Sir Isaac Newton^[4] made several observations about light in the early eighteenth century. In one observation, he concluded 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^[7] introduces another blend of tones and colors. He bases his correlations on the equivalence of each color to a fundamental sound frequency. 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).

The musician and acupuncturist Fabian Maman, along with biologist Helene Grimal, introduced sound therapy at the Cancer Help Center in Bristol, England. This treatment originated in ancient Japan and has been practiced there for centuries. Maman and Grimal^[8] worked with cancer patients at the center and observed the effects of the treatment.

Maman experimented with using specific sound frequencies instead of needles when treating patients with acupuncture. He found the results were just as effective, which encouraged him to pursue scientific experiments. Along with Grimal, he studied sound’s effects 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 cells’ shape changed in response to the note being played. Maman and Grimal concluded that the cells’ form and color, their biofield strength, and the note’s frequency were directly linked. They also found that they could reproduce these effects, though never exactly, suggesting each living cell has a 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.

Sound frequencies can be used, like 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 at a person’s body, they trigger reactions in the body’s cells, 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]
