Sounds of the Sun - pauloflight - 11-27-2020
An interesting ambient recording created by an artist called Indigo Aura, which involves frequencies “tuned to the oscillations found on the Sun’s surface.” Here’s how he describes it...
“Patches of the surface of the sun oscillate up and down with a typical period of about 5 minutes. These oscillations are due to sound waves generated and trapped inside the sun. The sound waves are produced by pressure fluctuations in the turbulent convective motions of the sun's interior. The five-minute cycle of the Sun’s surface corresponds to a frequency of about 0.0033 hertz.
If raise 0.0033 Hz by 16 octaves you will get 216.26 Hz. All of these numbers are an averaged and are approximated, so just rounding it off to 216 Hz is fine. This is why the reference pitch of this track is A = 216 Hz. This is one octave below A = 432 Hz, quite a well known frequency. Not that many people seem to know that the Sun sings a very low octave of 432 Hz.
If you lower A = 432 Hz by 3 octaves you will get A = 54 Hz. This is the frequency of the soft sine wave bass drone in the music. The volume of this bass drone is modulated at 0.421 Hz which is also a lower octave of 432 Hz. It is also modulated in longer 5 minute cycles just for good measure.
Volume modulation (rising and falling volume) on a sine wave is called an isochronic tone, these are often used for brainwave entrainment.”

Indigo Aura is also in the midst of releasing 10 tracks that are mathematically “tuned to the orbits of the planets in our solar system.”

Thank you pauloflight, beautiful.
