As a flute player, myself.....neat story! Thanks for posting. :)
Flute and pic player here, too!
Sure, sure, flute family but not to be pic-ky, but I’d say it was a piccolo instead of a flute considering the size and what I’d imagine the range would be.
Flutes Offer Clues to Stone-Age Music
Friedrich Seeberger, a German specialist in ancient music, reproduced the ivory flute in wood. Experimenting with the replica, he found that the ancient flute produced a range of notes comparable in many ways to modern flutes. The tones are quite harmonic, he said. A replica is yet to be made of the recent discovery, but the archaeologists said they expected the five-hole flute with its larger diameter to provide a comparable, or perhaps greater, range of notes and musical possibilities.
