Tesla tought Humanity, Physics is explained best in Terms of Frequency, Oscillation, Wave Harmonics, Octaves — so, Music is very much Applied Physics!
As our Planetary Objects move, oscillate circularly, we can apply Astrology to Music.
We have 12 Zodiac Signs, for we have 12 Months a Year. And we have 12 Tones within one Octave on our Piano Keyboard. So we can listen to planetary Birth Constellations of People.
Example. Tim was born with Sun (Father) in Libra and Moon (Mother) in Sagittarius. Anna was born with Sun in Aquarius and Moon in Libra. We find three unique Zodiac Signs, and their Tonal Equivalent would give a nice Open Chord. Just draw Intervals from Zodiac Wheel to Tonal Wheel and let it ring.
Tom and Anna would give a harmonic Couple or Friendship. Now, what about Major-Chords, Jazz and Blues? You get the idea! :-)
