It all begins with a sea creature—a snail called a conch—and the mathematically perfect spiral it transforms into a home, which we humans then put to our lips and play like a trumpet. Throughout time and cultures, conch shells have been used to communicate across great distances, from signaling on the battlefield to connecting with the divine. Hear stories about a jazz musician who plays the conch to connect with his ancestors, why a sacred Incan site way up in the Andes became a ceremonial conch concert hall, and how a conch shell made its way from the depths of the ocean to echoing through the Great Hall of The Met.
