Each one is handmade with a special bell metal alloy that produces a powerful harmonic resonance when played. Lightly tap the exterior rim and move the striker around the outer edge, firmly, slowly and with a stead even motion. The intensive energy that went into making the bowl is summoned forth. The vibration extends from the bowl into your body and soul, connecting you with the artisans and elements they wrestled with to create this fine work of art. Includes wooden striker.
