If there is one thing I learned while recording Mindfulness Bells Volume 1, it’s that meditation bells are not all equal! I sampled dozens of different bells and eventually exhausted my
own collection of over 65 different bells and meditation bowls before I
found "the one".
Just for fun, I decided to call him "Henry".
Henry is over 10 inches wide and he weighs 4 pounds. He is made from seven different metals and he was born in the Himalayas. He's a big boy, but he has a very calm disposition and he loves to sing in a deep, soft voice. Henry is the star of Mindfulness Bell Volume 1, but he promises me that he won't let all this sudden fame go to his head.
Henry has all the qualities of a perfect mindfulness bell. He’s never shrill, clangy or boomy and when you strike him he sings effortlessly. His two most prominent harmonics oscillate with a low delta frequency of 0.5 Hertz, and at a delta frequency of 4 Hertz. (You can hear these oscillations pulsing away in the audio sample). Much like the effect of binaural beats, these oscillations are deeply relaxing and can actually help to guide your brainwave activity into a state of deep meditation.
