Correction: Hertz is cycles per second, not vibrations per second. Vibration is defined as the movement of an object to one side or the other, which means that there are 2 vibrations per cycle, as Hertz only measures the peaks on the vibratory waveform, much in the way that wavelength only measures the distance between wave peaks. A metronome is a perfect example of such a vibratory waveform: each tick = 1 vibration. If the starting tick is on the left side (the "peak" on the waveform), then each return to the left side = 1 cycle. The arm is vibrating between two points, albeit at a very slow rate. Movement to one side = 1 vibration. 2 vibrations (2 ticks) = 1 cycle. Tuning forks were invented in 1711 by John Shore. They didn't have Hertz measurements back then, or the concept of vibratory cycles (they didn't know that sound is actually waves and that vibration corresponds to the movement of wave peaks through an object, i.e. one wave produces one back and forth vibratory cycle), so they measured vibrations per second. For example, what they called a C4 at 512 vibrations per second, we today call 256 Hz. Shore's A4 forks vibrate at 422.5 Hz by today's measurements, but Shore himself was tuning them to 845 vps. Just thought you might find that interesting.
Interesting, our solar system sounded lovely! Of course, concepts of consonance and dissonance are somewhat subjective. I, for example, often find two notes, one semitone apart to be a very pleasing interval, with a certain feeling of resolution. Another person might naturally disagree. It's just a matter of preference really. Great video though. Subscribed! ✔
Super interesting! Definitely going to try some of these ideas out next time I write!

Ah that’s very interesting, thanks for pointing that out!!
Super cool stuff!
Good stuff as always, Gu Wei!
We can also hear #frequencies and #emfs in what is passed off as "#tinitus"?

Thank you!! It is indeed very subjective :)
👍
Well, they may have sounded good, until after #colonialism and wars? 57%, 17:32!
