Pagon
NOT a bagpipe, but according to Bărbuceanu, who fails to reveal his source, a "variant of a bagpipe with 3 pipes, reported in the ethnological group Cashibo [Who refer to themselves as "Uni" [the people]; ws] of South America"; Because indigenous bagpipes do not occur in (South) America, whatsoever (!), this must be either a misinterpretation (possibly of a kind of syrinx [panpipe]), or an enigmatic error, because a seemingly reliable source (Database for Indigenous Cultural Evolution) explicitly states that "There are no traditionally-Cashibo musical instruments".
