This is the heaviest, most substantial piece of our antique Japanese singing bowls. The material is solid bronze. All patina is original. This bowl makes the most beautiful, enlightening, deep sound that is at once soothing and thought provoking. The Japanese singing bowls are very rare and hard to come by. They were used in temples to sync energy between human and nature. They summon blessings, clear one's mind and anchor one's thoughts. Striking the singing bowl begins a ceremony and symbolizes a fresh beginning. Complimentary leather and solid mahogany striker (new).
