What we learned in kindergarten music class about sound…. A vibration happens when something is set in motion. A guitar string vibrates when you pluck it. If you look carefully, you can see the string moving back and forth really fast, moving the air around it. The vibration travels through the air to your ears and you can hear it as sound! ................
