How we standardized music

The Gray Area is taking a short break this week — but we’ve got something special for you. We’re dropping an episode from one of our favorite podcasts, Unexplainable. In it, host Emily Siner explores deceptively simple questions: What is a musical note? And how did something as fundamental as the note A become standardized across the world? It’s a story about science, history, and the hidden complexity behind the sounds we listen to every day.We would love to hear from you.
