The MEINL Sonic Energy TCM cystal singing bowl 2-piece set is designed for sound therapy and meditation practices informed by Traditional Chinese Medicine. Developed in collaboration with Daoist priest and TCM practitioner Woodie Wulin, the set includes two bowls tuned to complementary yin & yang frequencies, each producing stable pitch and long-lasting resonance. Crafted from high-purity quartz, the bowls respond evenly when struck or rim-played, allowing controlled tonal interaction between the two voices. The 2-piece Yin & Yang set includes a crystal silicone rod, a singing bowl mallet and a padded carrying bag, making it ready for structured sessions, personal practice and transport.
