They move in a physically lesser motion. The feeling of the vibration is more subtle, when its stem is placed on the body. The sound does not last as long, but it is sharper more crystallized. The sound lasts longer, but is softer more diffused. They are heavier in weight. These Forks work more on the Physical level. One can feel the vibration more stronger at a deeper level, when its stem is placed on the body. This is due to the weights at the end of each prong. Tuning forks are used for healing because of their ability to emit vibrations and frequency. When a tuning fork is struck, it not only vibrates the fork itself, but it also vibrates the surrounding air space with the same frequency of vibration. This sends the vibration as an impulse through the air. This vibration can be harnessed to help increase the healing energy inside us. Made in High Grade Aluminium and anodized with GOLD coating.
