Yes, I think so. If the Earth's Schumann resonance is taken as the unit, then applying the harmonics theory produces a musical scale that exactly matches the one used in Indian music. I chose Indian music because it is not based on compromise scales as used in the West, but includes the different versions of notes that happen different ways with nearly the same frequency. It also shows about the right proportions of 2, 3, 5, and 7 ratios expected from the harmonics theory. e.g. Schumann frequency ~7.5 Hz when multiplied by 48, 54, 56, 60, 64, 72, 80, 84, 96 gives 360, 405, 420, 450, 480, 540, 600, 630, 720 Hz. The value of 450 Hz for A is fairly consistent with "concert pitch" and with what I believe (for other reasons) to be "natural frequencies".

It is worth mentioning also that when the harmonics theory is applied to the earth's circumference it does predict wave lengths that do match with things like cloud patterns. An example from my home country, New Zealand:


There is other stuff which I am not mentioning because I think it would sound a bit too new-agey for this forum but relating to frequencies in the human body.
