The aquavina was an experimental musical instrument created by Jacques Dudon.
It was essentially a variant of the Appalachian dulcimer, but with a metal resonator body partially filled with water. The player would agitate the instrument while playing, resulting in a constant acoustic phasing effect within the instrument's harmonics.
