Clicking your tongue is not as easy as it sounds and getting a loud sound can be even more difficult. For some people it comes naturally; for others, not so much. If you are one of the many who have a hard time mastering this skill, these steps and a bit of practice will help you get there.
Make sure your mouth is moist. If your mouth is dry, drink some water before attempting to click your tongue.
Place the tip of your tongue directly behind your front teeth.
Move your tongue along the roof of your mouth just a tiny bit toward you and away from your teeth until the tip rests right on the edge at the point just before your palette curves upward.
Stiffen your tongue and put pressure on this area with the tip.
Create a vacuum against the roof of your mouth with your tongue. Make sure that your tongue is not flat up against the roof of your mouth but instead is completely sealed all the way around the edge of the palette with a hollow space in the middle.
Lower your jaw and pull your tongue free from the vacuum to hear the loud click. You did it!
