The 417 Hz tuning fork is one step above the 528 Hz in the Solfeggio set. This fork is optional in Biofield Tuning, and is included in the Deluxe Toolkit but not the Basic Toolkit.
The 417 Hz fork can be used in place of or along with the 528 fork. When in tension, the 528 fork can sometimes emit a screechy sound. The 417 doesn't have this quality and can be a little easier on the ears. However, it doesn't have the crystalline brilliance of the 528 Hz.
Our unweighted tuning forks are precision-crafted and manufactured in America out of aluminum, using a metal alloy that is superior to regular machine-crafted tuning forks. They have been specially designed and created to stand up to the Biofield Tuning process which subjects the forks to distortion and can put stress on them.
As a result, they are more expensive than other forks. These forks last longer and will maintain their coherence and integrity, which is essential for effectiveness in sound healing. They also create a clearer, brighter, and longer-lasting tone than other tuning forks.
We recommend the use of our high-quality Canadian hockey pucks as an activator for all of our tuning forks.
