Zenergy Chime - DuoTibetan 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 manner. The two rods, are purposely tuned to almost the same pitch. When both are struck at the same time, an acoustical phenomenon known as "beating" is produced. A gentle tap of the mallet and the Zenergy Meditation Chime emits a powerful tone that lasts and lasts. 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. Relax, refocus, and rejuvenate with these good vibrations. Comes with wooden mallet and listening exercises. Cherry finished hardwood with 2 silver polished aluminum rods. Measures 7 1/2" long, 3" wise and 1 1/2" tall.
