Introduction to Weighted Tuning Forks

Introduction to Weighted Tuning Forks

Nov 3rd 2019

A weighted tuning fork is also known as an Otto Tuner. Otto is short for Osteophonic; “osteo” meaning bones and “phonic” relating to sound. So weighted tuning forks or Otto tuners bring sound to the bones.

Weighted tuning forks have a round weight at the end of each prong. The purpose of the weight is to create a stronger or heavier vibration which brings a more pronounced feeling when the stem is placed on the body.

Weighted tuning forks have been successfully used to relieve joint pain as well as reduce tension in muscles and nerve groups. Research by Dr. John Beaulieu has shown that two of the weighted tuning forks, the Otto 128 and the Earth (Ohm) tuner stimulate the release of nitric oxide, a gas in our blood known to reduce inflammation. Reducing inflammation helps to relieve the pain from arthritis as well as muscle spasms by improving blood flow.

The four most popular weighted tuning forks are the Otto 128, Otto 64, Otto 32 and the Earth or Ohm tuner. The numbers refer to the frequency of the tuning fork so the Otto 128 vibrates at 128hz. The Earth tuner vibrates and 136.1hz, the frequency of Earth. Omnivos Therapeutics has introduced a fifth Otto tuner, the Otto 48. No formal research has been done with this tuning fork but those who use it love the vibration it creates, particularly when placed on the sternum and chest area. 48hz is within the range of a cats purr which any cat lover will tell you is very soothing.
Custom frequencies can be made however the most effective range for weighted tuning forks is from around 20hz to 550hz. 

The weighted tuning forks can be placed anywhere on the body but each has a specific intention. We’ll discuss these intentions and the different ways to use the weighted tuning forks in upcoming posts.
