• The Rainmaker is a musical instrument or noisemaker from the north of Chile. It originates from the very dry Atacama area, where the Disaguitas Indians first made the Rainmaker for their rain ceromonies. It is made from dead, hollow, Copado cacti, from which the spikes are removed and inserted into the inside of the cactus. The Rainmaker is then filled with small pebbles and sealed at both ends. When the Rainmaker is overturned the pebbles fall from one spike to the next. In this way a uniform sound like flowing water or the splatter of heavy rain is created. This musical instrument may remind a listener of the life-giving force of water.
