What is "singing bowl"

n. A type of bronze bell, shaped like a bowl, related to Buddhist and pre-Buddhist religious practice.

Singing bowls (also known as Tibetan Singing Bowls, rin gongs, Himalayan bowls or suzu gongs) are a type of bell, specifically classified as a standing bell. Rather than hanging inverted or attached to a handle, singing bowls sit with the bottom surface resting, and the rim vibrates to produce sound characterized by a fundamental frequency ( first harmonic) and usually two audible harmonic overtones (second and third harmonic).

Singing bowls are used worldwide for meditation, music, relaxation, and personal well-being. Singing bowls were historically made throughout Asia, especially Nepal, China and Japan. They are closely related to decorative bells made along the Silk Road from the Near East to Western Asia. Today they are made in Nepal, India, Japan, China and Korea.
