Waterphones are stainless steel and bronze monolithic, one-of-a-kind, acoustic, tonal-friction instruments that utilize water in the interior of their resonators to bend tones and create water echos.

The rods can be played with superball mallets, by hand or with a bow. When the tonal rods are sounded some of the fundamental tones and/or harmonics are sympathetic to the bottom & top diaphragms.

When the attitude of the Waterphone is changed from vertical to horizontal and all in between the water is being moved on and off the bottom diaphragm as the tones are being sounded.

The water acts in 2 ways - (1) to bend tones via the weight of the water on the bottom diaphragm which lowers the tone when the Waterphone is in the vertical position and raises the tone when in the horizontal position and (2) creates acoustic, schiziosonic, modulations as in pre-echoes via the motion of the water and the relative speed of sound in water, air and metals.
