Whistling

sound · mouth muscles · music

Lips make the opening. To whistle, you create a small gap between your lips and blow air through it. The moisture on your lips helps the air move smoothly and create the right vibrations.

Your tongue is magic. Your curled tongue acts like a special sound chamber called a Helmholtz resonator. This makes your whistle sound richer and louder, kind of like how a guitar's hollow body makes music sound better.

Moving parts change notes. By shifting your lips, tongue, teeth, and even a tiny flap in your throat called the epiglottis, you can change the pitch and create different sounds. This is how you can whistle whole melodies.

Air turbulence creates sound. When you blow air through the lip opening, it creates swirling movement called turbulence. This turbulence bouncing around your mouth is what actually makes the whistling noise you hear.
