7 Metal Large Singing Bowl Set, D=4.75": Set includes wooden striker and bowl cushion. A singing bowl is a type of bell shaped as a bowl. They come in many shapes and sizes and ours are made using seven metals: copper, tin, iron zinc, lead, silver and gold. Singing bowls were traditionally made throughout Asia. The tradition continues today in Nepal, India, China, and Japan. Vibration is the most essential characteristic of singing bowls. For centuries the pure vibrations of singing bowls have been used for healing, meditation, making music and purifying negative influences. Doctors have used them for diagnostics, Monks used them for offerings, and Shamans used them for esoteric purposes. Handcrafted by our valued supply partners in Nepal.
