Record your laugh on tape, and videos. It's enough to put the camera included somewhere in the corner of the room during a meeting with friends and forget about her. By the way, the camera is able to amplify any imperfections. Examine their behavior on entry, volume of speech, the voicing of laughter. This will help to identify and correct significant deficiencies in expression of your emotions.
If you are shy own laughter, appreciate and analyze the reasons for this. Ask around others and relatives that your laughter is not so. Perhaps you have unsightly or discolored teeth and you all the time cover your mouth? Then the problem will go away by itself after you go to the dentist. If you emit a loud cackling or grunting, you need to have self-control and to work on their sounds. And the laughter in the wrong place and the wrong time and all said about low culture people. Nothing is impossible to do without a person's desire to get smarter and evolve.
Temperamental and short-tempered people are usually very loud and booming laugh. Try not to open your mouth wide and not too tip the head back. This will create a barrier coming from you sound and will make your laugh more cultural. Soon the tears should rush out of your eyes than you will stun everyone with his laughter.
Get rid of the wheezing, Parcani, deep-throat whistles, squeals, guffaws. These seemingly fun features of laughter can plunge into shock strangers. And the beauty of manners with such laughter to forget. For self-control think of invisible technique: pinch your hand or bite your tongue just a distraction from rassmeshili you subject matter and keep their own sounds.
Follow the situation of their own lips: the wider open the mouth during laughter, the more likely it is to accidentally spit interlocutor (or, again, to emit an involuntary sound). Try to prevent this moment, but deliberately the lips should not be too. Stretch your lips into a wide smile, and you will hear a completely different cultural and musical laugh.
Rehearse in front of a mirror. But try to stay relaxed. If you willfully and stagy laugh, to dramatically change the facial expression, to restrain themselves when others laugh, you just misunderstood.
Real laughter is good-natured, twangy, positive emotion. Treat everything with humor, know how to appreciate jokes and just relax. There is nothing more attractive than a sincere, cheerful, shrill laughter that transforms and makes a human beautiful.
