417 Hz Tuning Fork

The 417 Hz tuning fork is optional in Biofield Tuning, but much appreciated for its nuance. It can be used in place of or along with the 528 Hz tuning fork, and is recognized for its grounding and opening properties. When combined, the 417 and the 528 Hz Unweighted tuning forks create a binaural beat of 111 Hz. Many people enjoy using these two forks together, holding one up to each ear to experience the 111 Hz.
