During the Inca times, often feathers from the condor or other birds were used to adorn the instruments while creating their mystical spirit.Its construction resembles closely the Peruvian Antara and the Andean siku. To make a Rondador very thin walled bamboo canes are chosen to facilitate resonantly smooth pipes. The instrument has all the tubes arranged in a single row and it is played by blowing simultaneously in two contiguous tubes at once (none like other Andean panpipes in which only one pipe is blown at a time). The pipes are tuned in a pentatonic way interlaced from major to minor: The essential characteristic that sets the Rondador apart from other panpipes is that each pipe is laid down followed by a pipe tuned on its lower third, thus allowing to produce a melody with a harmony in parallel thirds. Nowadays Rondadores exist in an assortment of tunings.
