One can discern by the reflecting light in the picture that the bones were very thin. And thus must have been played like the Andean Quena. Blown over the thin wall. One of those flutes (number 2 from top) had 5 holes and tuned like the 7th century Japanese Shakuhachi which tuning is found later in the Native American Kiowa Love Flute. The pentatonic scale played with rhythm sounds like Andean music. Did somebody have a flute when they crossed the Bearing Straights?
One wonders if the ancient Jiaju Crane flute made from the wing bone of ancient cranes may have come from an Ancient Chinese Restaurant.
Clay pan pipes and human bone quenas were found in the Andes.
We also find double flutes depicted on ancient Greek vases.
