An instrument which was developed while in residency in in 2004. Similar to a Mouth bow or Berimbau the Waterbow is either played by running water which excites the string or moving the bow back and forth when in still water. A resonator amplifies the sound as a personal "headphone" for the player. An ear pressed directly against the branch is also possible for a more introspective listening. The first listening experiments where conducted with only branches. The sound of the running water would modulate through the wood and depending on the type of wood and it length and thickness produce different timbres and volume of sound. Collected branches and listening to the sounds of the Cascata is now an annual event during the Stazione di Topolo.
