More correctly called tingshas, these are sets of 2 single cymbals joined together by a piece of leather. Generally made from nickel and bronze (which is a combination of copper and tin). TIngshas are used in spiritual practice and meditation in order to focus the mind, over parts of the body during healing, in feng shui, during space clearing and cleansing rituals and in certain types of dance. With correct use they tend to reverberate at a high frequency and create waves of sound that delight the ear and enhance renewed silence.
