The tarka is an indigenous hand carved square flute of the Andes.  This 1940s painted tarka is from Bolivia, featuring the carving of a man playing panpipes and an alpaca at the bottom.  It has an end-blown duct flute (whistle) mouthpiece, a cylindrical bore, and six equidistant finger holes on the top side.  Tarkas have three variants:  Large (seen here); Medium (tuned by a fifth above); and Small (tuned by an octave above).  These three size tarkas are played together in an ensemble accompanied by the tinya (found in this collection) and the wankara, a large double-headed cylindrical membranophone of the Quescha- and Aymara-speaking people of the Bolivian Andes.

These ensembles (consorts) are called tropa in Bolivia and can be seen at Carnivals and family celebrations.
