Peruvian Aerophone (Pan Pipes): "Zampoña"

This zampoña, a wind instrument which belongs to the pan-pipe family, is made up of a series of cane tubes of varying sizes bound together. The size of the tube determines the musical note. The zampoña comes in a wide range of variations, depending on the region, where the length, location and quantity of cane tubes vary. The pan flute is played by blowing horizontally across an open end against the sharp inner edge of the pipes. Each pipe is tuned to a keynote, called the fundamental frequency.
It is frequently played in nearly all the festivities in southern Peru.

The earliest known example of the zampoña was found at Cahuachi, Peru, dated to 4200 BC - a time that corresponds with what is called the Honda Period of this region. Researchers point to three different ancient Peruvian cultures as early users of the panpipes: the Nasca Culture (1,100 BC - 750 AD), the Paracas Culture (600 BC - 175 BC), and the Moche Culture (100 AD - 800 AD). Reed, cane, ceramic, condor quill and bone panpipes have been found across the Andes.
