In 2018 I was researching color and sound therapy practices, specifically practices where color or light and sound were combined. I came across Dinshah Ghadiali’s theory of chromotherapy, therapy with combined light and color. In 1920 introduced to the public a machine called the Spectro-Chrome, an analog chromotherapy device using lamps with specially designed color gels that he claimed could heal parts of the body for treating specific ailments. He also set up a system to determine the closest relationship between sounds and colors of light over the electromagnetic spectrum, to find musical notes that could support a chromotherapy session for a specific color. The idea was to use a warm glow and then a cold wash (or vice versa) for balancing, with a corresponding sound.

I made the “Color Meditation” series of color and sound videos by combining these chromotherapy colors and the notes associated with them, layering each sonic tone to create an auditory hallucination or isochronic tone with a beating effect. I included the audio as a harmonizing drone in the Tuning House.
