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 heal individuals suffering from neurotic and mental illnesses in the early part of the twentieth century.

As a death-related counselor in Florida, USA, Helen Baker,^[2] a light therapist, collaborates with people in grief. She integrates music and light into the counseling of bereaved individuals. She asserts that light waves, represented by colors, correspond to the tonal frequencies of sound; furthermore, employing light and sound as pure vibrations holds significant potential in psychotherapy, physical healing, and transformation of personal and cultural consciousness. Baker believes that utilizing music and light aids troubled individuals in processing grief or recovering from a challenging diagnosis. However, this field has yet to be explored to its full potential. 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 clarifies that the body acts as a receiving station for energy. When incoming vibrations align with the corresponding frequency of a body part, they resonate. Conversely, when this alignment is absent, disharmony occurs. When intense, non-productive thoughts or emotions are present, as experienced by a bereaved person, the vibrations struggle to flow freely throughout the body, leading to blockages. Disease arises from the vibrational activity of a specific organ deviating 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 say 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 substituted states of relaxation and physiological balance. Their breathing becomes deeper and more regular. Their pulse slows down, and the hemispheres of their brain 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] means 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 designates 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 presents yet another combination of tones and colors. He bases his correlations on the equivalence of base sound frequency to each color. For example, he says that the fundamental frequency for his Spectro-Chrome red is 436,803,079,680,000 cycles per second, and to arrive at a frequency in the audible range, he divides this figure by two 40 times. In other words, Ghadiali scales the tone’s frequency by 40 octaves. This operation gives him the frequency in sound for red as 397.27 Hz. Ghadiali says this frequency is the closest to the tone G (g’ in the one-line octave).^[7]

The musician and acupuncturist Fabian Maman and 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 and observed its effects.

Maman experimented with imparting precise sound frequencies instead of needles when treating his patients with acupuncture. He found that the results were just as effective, which motivated him to begin experimenting scientifically. Alongside Grimal, he examined the effects of sound on blood cells microscopically. They photographed the cells using Kirlian photography while playing notes from the chromatic scale. To their surprise, the photographs revealed color suffused into the blood cells when they struck a particular musical note. They noticed that the shape of the cells changed in response to the note played. Maman and Grimal deduced that they observed a direct affinity between the cells’ form and color, the strength of their biofield, and the frequency of the note struck. They also noted that these effects could be reproduced, although never precisely, indicating that each living cell had its distinct quality.

The reproduction results depended on several factors, such as the vitality and state of the human being 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, restoring the individual’s health.^[2][3] These low “beat frequencies” have the same therapeutic effects as light.^[9] When one or more chosen sound vibrations are projected onto an individual’s physical body, they create reactions within the body’s cells, thus destroying the diseased blood cells.^[8]

Using Kirlian technology, an Indian researcher, J. M. Shah, took pictures of the electromagnetic energy glow around the human body. He discovered that disease first appears in the aura before transferring to the physical body. The illness can reach the physical body in six to eight months. Thus, he established that color therapy could be used preventively.^[10]
