Our weighted tuning forks are based on the Schumann Resonance (7.83 Hz) and comprise the 7th and 8th harmonic of this important frequency. They can be used separately or together to create a binaural beat of 7.83 Hz that can be applied to the body via the handles or listened to in either ear. If you would like just one fork, we recommend the 62.64 Hz. If you would like just one fork, we recommend the 62.64 Hz.
