Music's Secret Math
What makes music sound pleasant to our ears?
You're listening to your favorite song, and suddenly your whole body wants to move. Your foot taps. Your head bobs. Something about those sounds just feels right. But why? What makes some combinations of sounds feel like a warm hug for your ears, while others make you want to cover them?
Sound is really just air molecules bumping into each other in waves, like ripples spreading across a pond. When something vibrates — a guitar string, a drum, your vocal cords — it pushes the air around it, and those pushes travel to your ear. The faster something vibrates, the higher the pitch. A piccolo vibrates hundreds of times per second; a tuba vibrates much slower.
