Fascinating topic!
I’ve often thought that there had to be some sort of connection between the 7 musical notes, the 7 planets recognized by the ancients, the 7
chakras, the 7 greek vowels, and the 7 principle colors of the visible light spectrum.
I looked deeply into this subject last summer in hopes of coming to some sort of conclusive pattern of correspondence, with the idea that if it could
be done, the practical applications for this knowledge would be endless and incredibly efficacious. I never came to such a conclusive discovery, but
found some fascinating information, not all of which I can recall at present, though I will share some things that might be helpful to others.
Firstly, I highly recommend taking a look at this book called ‘Esoteric Harmonics’ written by a member of the theosophical society. You can read
it online here:
Esoteric Harmonics
It is not generally known, but the standard Western system of musical pitch (i.e. note frequency), in part, approximates to the same frequency
pattern as our solar system (i.e. as taught by Theosophy). This should come as no surprise since the universe can be thought of as an enormous cluster
of interwoven vibrating (or oscillating) energy waves. Indeed, it could be said that the vibrations that compose our universe (and everything in it)
represent the reverberating sound of the Voice of God.
the frequencies of the natural notes of our musical system (i.e. as represented by the white keys of a piano keyboard) can be re-calculated so
that they fit neatly into a framework that is based on multiples of the number 49. And this can be done without varying the notes significantly from
their original values in the standard system.
That book contains some interesting insights into the great pyramids, the fibonacci sequence, the golden mean, and how it all fits together.
Another interesting, though perhaps unrelated and meaningless, anomaly I discovered had to do with the 7 heavenly spheres the ancients spoke of. The
order the ancients listed them was: Moon, mercury, venus, sun, mars, jupiter, and saturn. I then applied the perfect fifth, which in music theory is
regarded as the most stable or harmonious interval other than the octave, and remarkably, the order results in the days of the week.
If you take the the moon (corresponds with monday), then skip 3 planets you come up with mars (corresponds with tuesday), skip 3 more and you get
mercury (corresponds with wednesday) and so on.
The significance of this could be that there may be an inherent “harmony of the spheres” as pythagoras put it, and this esoteric knowledge could
be ingrained into our very calendars.
Also, is it possible that this may be the underlying mechanical process of astrology? The fundamental problem with astrology is that it doesn’t
explain
how the planets could influence us, but what if vibrational frequency is the medium in which the motion of these heavenly spheres
affect our behavior?
Perhaps frequencies are the key to understanding our universe and how it is governed. As others have pointed out, the study of cymatics has shown that
frequencies have the power to organize matter into natural geometric forms. If we apply this concept to a grander scale (As Above, So Below) then it
could explain the perfect harmony in which our universe is governed.
If one is inclined to research the more scientific and mathematical foundations of this subject, I would suggest looking into
Hans Kayser.
Hans Kayser was a German art and music theorist and founder of modern harmonic research in the 20th century.
The acoustic-musical laws in a more comprehensive, more universal overall context, focusing on a possible relationship of these laws to the planets
and spheres to make, was a beginning with Pythagoras of Samos in ancient and medieval popular exercise (see harmony of the spheres ), which in modern
times, although lost its appeal but did not disappear entirely.
Since 1920, Kayser was working on the reformulation of the Pythagorean thought and tried the findings of Johannes Kepler (Harmonic mundi) and Albert
Thimus of a harmonic order of the world on the basis of metaphysical speculation to revive.
