Schumann Resonance (7.83 Hz)*Prints are unframed 'Cymatics' is the physics of sound made visible. The inspiration for the particular frequency used to create this image came from the Schumann Resonance: Earth's resonant vibrational frequency. The Earth has an electromagnetic field surrounding and protecting all living things with a natural frequency pulsation of 7. 83 hertz, along with progressively weaker harmonics at around 14. 3, 20. 8, 27. 3, and 33. 8 Hz. These oscillations
