There is a cosmic cycle so vast the mind struggles to contain it: the Platonic Year, the 25,920 years it takes for the Earth's axis to complete a full precession around the ecliptic. Hans Cousto — Swiss mathematician and musicologist — translated this cycle into frequency: 86.03 Hz, note F2. This gong doesn't tell time as we know it. It tells time as the universe knows it.

What is the Platonic Year
The term "Platonic Year" refers to the great cycle of the precession of the equinoxes: 25,920 Earth years. Hans Cousto, applying the principle of the cosmic octave, derived the frequency corresponding to this cycle: 86.03 Hz — note F2. A sound that vibrates in resonance with the great rhythms of the cosmos, perceivable not only through hearing but with the whole body.
- ✦ Frequency 86.03 Hz — fundamental note F2, calculated by Hans Cousto
- ✦ Cosmic cycle of the 25,920-year equinoctial precession translated into sound
- ✦ Deep, enveloping timbre — the sound opens slowly, expands and envelops the surrounding space
