Set of Andean, Peruvian bamboo pan pipes in standard 6 and 7-pipe "Chulli", "Chill"or "Chili"configuration. Also called Zampoñas. May be fastened and played as a pair, or separately in coordinated hocket groups. Very good quality and well tuned. Unadorned and labeled by numbers and/or note names. 10 complete pairs, plus two extra 7-pipe units. I bought these and labeled them for use in an upper elementary school classroom, but I am now retired and clearing out my collections. Come over and try them out!
