It is the scariest musical instrument and often appears in the horror scenes of movies. It comes from America, and its voice often appears in the soundtrack of movies. Its name is beautiful, but it is the scariest musical instrument in history, and it has produced many horrible sound effects in modern movies (such as Alien, Invasion of Blood, Star Trek, Crouching Tiger, Hidden Dragon, Ghost Water, etc. ).
It consists of a stainless steel bowl or basin, a "neck" connected to the top and a brass band welded to the outer edge of the bowl or basin.
The way of playing the water harp is to make the resonator and copper rod vibrate and sound by friction or percussion. Common sounding accessories include rubber hammer, tuning fork, wooden stick, violin bow, etc. After the water in the water harp is filled with water, the water in the resonator can make a curved tone under the shaking of the player, accompanied by the echo of water. This relatively free vibration mode exceeds what we usually know about musical instruments.
