Buddhists use this bowl to meditate. Sound healers and therapists like to add it to the soundscape as it is strong and soothing.
The Black Ching Gong is best played by striking the top edge, or rim, with the wood and rubber mallet that is provided with it. These bowl gongs produce beautiful tones, but are not well suited for 'singing'.
You can get remarkable tones that are both clarion and subtle. They stay in a specific range but sustain and hold for a good length of time.
