Many years ago, archaeologists discovered skull-shaped whistles at Aztec sites. They believe that priests used these instruments during human sacrifice ceremonies. Quijas Yxayotl, a musician who specializes in pre-Columbian Mesoamerican traditions, developed a modern version. It produces a sound just like that of people screaming in terror. The whistle is like something out of a horror movie!
You can hear Yxayotl perform the Aztec death whistle in this video. Skip to the 0:49 mark to hear the screaming.
I'm envious. Those of us with Scottish heritage have no instrument comparable to the Aztec death whistle.

The Aztecs had a lot of horrible practices. Bagpipes have nothing on that whistle.
