Have you always wanted to be able to whistle but never figured out how?
Today is the day to learn the solution.
Let's start:
Step 1
Form the letter 'A' with your index and middle fingers. Gather the remaining fingers as if it were a fist.
Step 2
Inhale your lips from the inside just a little, folding your tongue as in the picture, around the teeth. It may take some effort to decide exactly how much to tighten your lips.
Step 3
Now you need to move the tongue to the right position. Using your fingers, gently press the tongue back into the mouth and gently press its tip down.
You need to end up with a "curve" formed by your language. No more than 1/4 of the length of the fingers should be in the mouth.
Step 4
Breathe through the air that forms in your mouth. If it feels like air is just passing over your lower lip, then you did it correctly. If it appears to be passing through your upper lip as well, you should reduce the size of the air passage using your fingers.
