Tibetan singing bowls are traditionally constructed of a 7 metal alloy, said to include gold, silver, copper, iron, lead, tin, and mercury. Both Buddhism and Hinduism include ideas of the role of sound and vibration in trance and transformation, as do other religions. Today, singing bowls are most often used as meditation aids, however, anyone can benefit from the relaxing, soothing effects of the sounds produced. Many people are also mysteriously drawn to the sounds and find them fascinating regardless of any spiritual connections.
