Standing bells originated in China. An early form called "nao" took the shape of a stemmed goblet, mounted with rim uppermost, and struck on the outside with a mallet. The manufacture and use of bowls specifically for 'singing' is believed to be a modern phenomenon. Bowls that were capable of singing began to be imported to the West from around the early 1970s. Since then they have become a popular instrument in the US-originating new-age genre often marketed as 'Tibetan music'.
