The first bowls were made from an alloy of various metals and were used already 6000 years ago in the Far East. Tibetan singing bowls are a mysterious acoustic phenomenon, which was discovered by “spiritual tourists” in the Himalayas and after the Chinese invasion of Tibet appeared also in Europe and the USA. A Tibetan singing bowl is a type of bell that vibrates and produces a rich, deep tone when played. Also known as singing bowls or Himalayan bowls.
