I have been interested in the attributes of light and sound for a long
time. The effects of resonance, harmonics, harmony, discord and the
many other aspects of sound have fed my interest in music for some
forty years now. Though I have some degree of red-green
color-blindness I have enjoyed painting and I have made my living in
the printing trade for twenty five years, developing some expertise in
the subtle manipulation of colored pigments to achieve a variety of
results.When I encountered the system of correspondence between color and
sound which is presented as “The Queens Scale” in much esoteric
teaching I was intrigued. Of course my first question was “What is the
connection?” Why is it said that the pitches of the western
twelve-tone scale correspond to the twelve primary, secondary and
tertiary colors? Besides the very nice (and suggestive) fact that
there are twelve members of each set, what do they have in common? It
seems to me that the clear answer is that light and sound are both
conveniently described as waves, albeit of greatly different
frequencies. Perhaps, I thought, there is an instructive relationship
between the frequencies of the light of the twelve colors and the
frequencies of the sounds of the twelve tones. I decided to
investigate.[SNIP]
I was surprised to find that the wavelengths of the colors did fall
approximately within the range of one octave! Perhaps they actually do
correspond mathematically to the pitches of the twelve tone scale. The
next step was to determine what note each of the colors actually is.



I take it you’re familiar with synaesthesia.
Yes. But this is talking about something else. Where synesthesia has to do with processes in the brain and sensory processing, this is talking about the physical properties of two media.
Right, but the two ideas seem to support each other. Nifty in any case.
