Our Earth Crystal Tuner is calibrated to 4096 cps, derived from an 8 cps fundamental tone that rises through nine octaves (8 cps, 32 cps, 64 cps, 128 cps, 256 cps, 512 cps, 1024 cps, 2048 cps, 4096 cps). This frequency corresponds with the Earth's own natural pulsation. The ninth octave of this upper overtone series was celebrated by Alexander Scriabin, a Russian composer, as a gateway to the divine realm. He believed this octave could create a bridge between Heaven and Earth, and that his final composition Mysterium could be played in India by bells suspended in the clouds, resonating with the 9th octave harmonics.
