Wiggles Make Music
What makes a high note high and a low note low?
When you pluck a guitar string, or blow across a bottle, or hear someone sing — what actually makes one note feel high and another feel low? The answer is invisible, but once you see it, you'll hear music differently forever.
Every sound you've ever heard is made of vibrations — tiny, fast jiggles traveling through the air. When something vibrates, it pushes the air around it back and forth, and those pushes travel to your ear as a wave. No vibration, no sound.
