Whistling

Whistling is making a sound by blowing air through your lips or teeth. When you blow air through your lips in a certain way, it makes a high-pitched sound, kind of like a bird. You can also make the same sound but with your teeth, which is called tooth-whistling. To whistle with your lips, make a circular shape with your lips and blow air through it. To tooth-whistle, press your lips tightly together while keeping your front teeth apart. Then blow air slowly through the small gap created by your teeth. Whistling is fun, and it's a great way to make music without instruments.
