Welcome to the Sound Studio! Every sound you hear starts the same way: something vibrates, moving back and forth very fast.
Pluck a guitar, and its strings vibrate. Hit a drum, and its skin vibrates.
Put rice on a drum and tap it. The rice jumps, because the skin is shaking.
Your voice works this way too. Touch your throat and hum. You can feel your vocal cords vibrating!
Try it with a grown-up: hold a ruler on a desk with one end hanging off, then flick the end. Watch it blur as it vibrates.
