I'm trying to reconcile the physical meaning of frequency/vibrations with the metaphysical meaning.

Physically, frequency is cycles per second or Hertz. I deal with angular frequencies as well. The frequency of a musical note is the cycles of excitation/movement per second of the air when the sound (elastic waves) propagates. The acoustic piano has a range of fundamental frequencies of 27.5 Hz to 4186 Hz. HArmonics are multiples of the fundamental frequency.

Metaphysically, the masters describe high/spiritual) vibrations and low (materialistic) vibrations, but it is not well specified what vibrates. The string, the reed, and the air vibrate in a musical instrument. In an earthquake, the ground vibrates. In the astral or causal realms, I wouldn't know.
