Two rods tuned to similar pitches produce a pulsing tone called "beating."
Tibetan monks use small cymbals called tingsha, which are sounded to mark the beginning and end of a period of meditation. You can use your Zenergy Meditation Chime in much the same way. The two rods are purposely tuned to nearly but not quite the same pitch. When both are struck at the same time, an acoustical phenomenon known as "beating" is produced. The rods will seem to ring with the same pitch, but you will notice a distinct pulsation or rhythm in this case, approximately 12 beats per second.
Sounds like this are often used in meditation and healing, because they help us to focus and redirect our attention to the sounds within.
