Very low frequency circling vibration, easy to keep, a little difficult as the resonant metal begins to bounce from the wand, a considered amount of pressure at certain angles needs to be applied with the fingers and wrist. So big i can fit my face in the bowl which is great with the long lasting resonance to really wash my head in the sound. Bowl can be played with two rubber headed mallets and added to gong work and other percussive instruments. When struck creates a very long lasting sound, resembles the sound of a grandfather clock in an echo chamber, beautiful overtoning chimes. Yet to try different levels of water in the bowl to see what difference it makes to the over all sound. A well presented and crafted product with a distinct individual sound.
