You can also moisten your lips by drinking a glass of water.
It is not especially important how the remaining fingers rest as long as they do not get in the way. If you are not a fan of the “okay” finger configuration, experiment with other ways to whistle with your fingers.
You should apply enough pressure with your fingers to cause the tip of your tongue to curl back slightly, but without folding it completely over. Be sure to wash your hands before putting your fingers in your mouth.
Make sure that all other areas around your fingers are airtight. If air escapes from any other position at the front of your mouth, you will not get a strong whistle. Wet your lips again if they dry up throughout this process.
Do not be discouraged if you do not get this right on your first try. For many people, it takes time and practice to master this whistling technique. Make sure the blown air is focused and narrow so that the air flows through the correct space.
Light and quiet whistle sounds mean that you are not blowing hard enough, but that you are blowing air through the space properly. You can practice and make adjustments while walking, or while listening to music.
At the beginning you will hear air flowing through your lips without hearing an actual whistling sound. The best thing to do during this stage is to go back through the steps required to whistle loudly and make adjustments to your technique. Later you will hear a sound similar to that of a jet engine. You may hear something close to a whistle, with some vibration in your lips. From here, it’s mostly a matter of readjusting your fingers until you can get a clearer sound. Soon you will hear a whistling sound, but the sound will remain soft and airy. This is due to air leaking from outside the space between your fingers. So you will need to tighten the seals made by your tongue and lips. Finally you will find a full-powered, clear whistle. If you make it to this point, you now know how to whistle!
This circular shape is where the air will flow through, ultimately making the whistling sound.
Your top molars will be touching your tongue as well.
Start with a gentle blow of air until you can hear a low whistle. This will let you know that the technique is right.
Proper technique and blowing harder will create the loud, intense whistling sound you are looking for.
