The white-frosted Meinl Sonic Energy Planetary Tuned Crystal Singing Bowls are made using the calculations of Hans Cousto (The Cosmic Octave) to match the frequencies of the sun, moon, and planets. Each one is tuned to produce the corresponding frequency of the celestial body. These white-frosted singing bowls are made of high-purity quartz creating a charming aura with their sound and design. Their long-lasting, spherical tone spreads when the singing bowl is gently tapped or rubbed so that the energy can be felt in the entire surroundings. All Crystal Singing Bowls are delivered with a silicone ring to avoid possible impact and to ensure the best resonance. You can use crystal singing bowls for various purposes: Chakra healing, meditation, sound therapy, yoga, improving your home Fengshui, adjusting your emotional state, or even room decorating.
