The Aztec death whistle is one of the most enigmatic and haunting musical artifacts of the ancient world. It is a small, ceramic whistle shaped like a human skull or a decapitated head, with intricate carvings and details. When blown, it produces a sound that resembles the scream of a dying person, a howling wind, or a wailing animal.

The whistle was first discovered in the 20th century during archaeological excavations in Mexico, primarily within the sites associated with the Aztec civilization (1345-1521 CE). However, its origin, purpose, and use remain largely unknown and debated by scholars and enthusiasts.
