In the Buddhist tradition, they are played to signal the beginning and the end of silent meditation cycles. Tibetan bowls emit very pure tones, close to sine waves. Their sound is a synonym of purity for our ears. Like a bell, the tone is produced by striking the side of the bowl with a wooden mallet. By running the mallet around the bowl - only with slight pressure - a pure tone will eventually rise. When this happens, the bowl is said to sing - hence its name.
