You may need to move your lips around when you begin to practice the whistle, but for now, keep them wet and tucked inside your mouth. [1] X Research source
You can also use your pinkies. Hold your hands the same way, holding up your pinkies instead of your index and middle fingers. [3] X Research source You can also use one hand. Hold one hand up, and make the okay sign by pressing the tip of your index finger and thumb together. Then separate your fingers slightly, leaving a small space between your fingers for the air to escape. Keep your other fingers out straight. [4] X Research source
Curl your tongue toward the back of your mouth. Using your fingers, fold the tip of your tongue back onto itself. The back of your tongue should cover a wide portion of your lower back teeth. [5] X Research source [6] X Research source
Don’t blow too hard at first. As you blow, adjust your fingers, tongue and jaws to find the bevel’s sweet spot. This is the area of maximum efficiency for your whistle, where the air is blown directly over the sharpest part of the bevel.
Make sure you don’t breath too fast or too often while you are practicing. You don’t want to hyperventilate. If you take your time, you will have more breath to practice with. Using your fingers to apply some extra downward and outward pressure onto the lips and teeth may also be helpful. Experiment with the position of the fingers, tongue, and jaw.

Your bottom lip should be snug against your lower teeth; if you need help with this movement, press your index and middle fingertip on either side of the mouth to draw your lip slightly out at the corners and over your lips. [11] X Research source
As an alternative, flatten out your tongue so that the sides of your tongue are pressed against the edges of your back teeth. Roll the tip of your tongue down slightly, making a “U” shaped dip in the middle where air can pass out from behind your tongue. [13] X Research source
Make sure you don’t breath too much or too fast while you practice. You don’t want to hyperventilate. If you take your time, you will have more breath to practice with. [17] X Research source
