Waterphone
（重定向自Aquaphone）
A waterphone (also ocean harp or AquaSonic waterphone) is a type of inharmonic acoustic percussion instrument consisting of a stainless steel resonator bowl or pan with a cylindrical neck and bronze rods of different lengths and diameters around the rim of the bowl. The resonator may contain a small amount of water giving the waterphone a vibrant ethereal sound that has appeared in movie soundtracks, record albums, and live performances. The instrument was invented and developed by Richard Waters.
