Each Planetary tuner is tuned to the frequency of a different planet, this one to the Moon, and activates the different astrological qualities associated with that planet when played. The tuning fork is engraved with the name of the planet and the exact vibrations per second of the tuning fork
Hold your tuning fork by the stem between your thumb and first finger. Do not apply a lot of pressure. Gently tap the weights on your knees, tapping pad, or palm of your hands. This will set the weights in motion and create a clear, deep and sustained tone. Bring the double-pronged side of the fork about an inch from your ear(s) and adjust the distance for volume. You can use this pitch as a guide for chanting, or simply for listening or meditating.
