Meinl Sonic Energy White Frosted Crystal Singing Bowls are made of high-purity quartz to create a soothing tone when gently tapped or rubbed with a crystal singing bowl mallet (mallets and rods sold separately). These bowls feature an elegant white frosted exterior finish. Ideal for sound healing and relaxation, this singing bowl fits a variety of settings from yoga studios, close meditation spaces or sound baths in large, wide-open rooms. It's also perfect for using at home to relax or meditate on your own. Its long-lasting resonance can easily be felt as a positive energy that flows throughout your surroundings. Our White Frosted Crystal Singing Bowls are expertly tuned based off the tuning standard of A4 = 432 Hz, and each bowl is tuned to a note that corresponds to one of the seven Chakras. This bowl has a diameter of 12" and vibrates at note C4. The corresponding root chakra promotes more vital energy, self-confidence, stability, assertiveness and better digestion. All of our crystal singing bowls include a silicone base ring to ensure the best possible resonance. Designed in Germany, Meinl is a family-owned musical instrument manufacturing business that was established in Germany in 1951. Our expert German designers have deep relationships with our builders to ensure you're delivered the absolute finest quality.
