Press play on your favorite song and something strange happens. Your foot taps. Your chest warms. Maybe you grin for no reason at all. Music is just air wobbling against your eardrum — so how does a wobble in the air reach all the way into your mood?

It starts with vibration. A guitar string, a drum, a voice — each one shoves the air into tiny waves. Those waves jiggle a thin patch of skin deep in your ear, which jiggles tiny bones, which jiggle a curl of fluid full of microscopic hairs. Each hair answers to a different pitch, like a row of tuning forks waiting to be tickled.
