I am fascinated by the Harmonic relationships in our Universe, and in this paper I have delved a little in trying to correlate Pythagorean Natural Harmonics of Sound with 4 other series of 12 semitones derived from that Natural Harmonics Fundamental. As explained in the paper, I correlated a Fibonacci sequence to that Fundamental, as well as a Phi correlation based in 1:1.61803399 and another based on its inverse 1:0.61803399. I decided to use Pythagorean Just Tuning derived from A4=432 Hz, which I find interesting and also because it relates to the number “9”. In addition I am relating work done with our Home Note, and Birth Note according to Zodiac/Note/Color research that I found in the Internet, credited to the likes of Rudolf Steiner. I intend to apply these Fq’s in my practice, but I know this is the tip of the iceberg, and that I need to go further down all these rabbit holes.
