The pifilca (Mapudungun language: onomatopoeia of its sound) is a type of ductless flute, resembling a silbato, found in Patagonia, particularly the Argentine provinces of Río Negro and Neuquén.
Description
It is an aerophone resembling a flute with a longitudinal filo-flauta, with the tube closed at its lower end and the middle portion with a singular perforation.
It is made of wood of 30-40 centimetres in length, lacking an orifice to obturate. The tube is bored through its length, approximately halfway through. The instruments emits only one sound, and its one note mixes with a song or group of instruments in a rhythmic manner.
