I believe you are most curious about not being able to whistle at night. Why can't you whistle at night? How did you come from not being able to whistle at night.
&Click next to see why you can't whistle at night
The origin of the custom of whistling
This custom originated from the ancient military camp. The reason is that the Sergeants are not allowed to make any noise at night when they are marching and camping. It is estimated that the first one is to be afraid of interfering with the sergeants on duty who are responsible for guarding; the second one is to be afraid of "howling camp" (howling camp - the phenomenon that the camp suddenly makes a sharp noise at night, shooting nervous soldiers, causing chaos, leading to either the enemy's surprise attack or the sergeant's mutiny). Therefore, the military regulations state that there should be no whistling, screaming, or mischievous behavior at night.
In ancient times, people were superstitious. They believed that "Xiaoying" was caused by the evil spirits who died in the war. Therefore, as soon as it was extended, there was a saying that whistling at night would lead to evil spirits.
According to the old people, in the past, people's life was very bad, basically there was no light. Everywhere you go is dark, so those who are not reconciled to death, should be said to be ghosts? They will come out and flee everywhere. It is said that people who have met will hear the sound similar to whistling. But I think maybe that's why people didn't know much about science at that time. In real life, there can be no ghosts. As for no whistling, it's a little bit related to the heat and the fact that most old people don't like to hear people whistling. I always feel indecent.
The old people all say that whistling at night is' cool wind ', which is what we call' ghost '. But I personally think that's what the old people do to scare the children, because the old people all think that the whistling people are not good people. The original scoundrels and people who don't do their jobs are very lazy whistling all day. Now, it's nothing, as long as you like it.
Why you can't whistle at night
Generally speaking, the room whistling parents will be more taboo, children whistling can not scold, had to give a white lie to cajole children not to whistle in the room. Because all of us are afraid of snakes. Based on this, when we whistle again, we will worry about really leading snakes out. So I won't whistle in my room any more. My family never tell me why. Just now I read a post and mentioned something similar: eels are very similar to Japanese 'ichthyosaur' or 'water demon'. This eel is huge in size. Once it rushes into the boat at will, it will add a lot of trouble to the fishermen.
Because of its huge size, it can't be caught by ordinary fishing nets, so it often falls into the sea. When fishing at sea, if you encounter this kind of eels, you should absolutely avoid letting it close to the ship. Some eels are several meters long. If they are not careful, the boat will be entangled by its body. People can only do nothing about it. If the owner's skill is poor, the ship will even be towed away by force, so the huge eel becomes the so-called 'monster'. In the paintings of the Edo era, we can often see the 'strange eel', which is generally called the 'water demon'. Ships sailing on the sea will be entangled by it unconsciously, and it will turn away after smearing the thick mucus on the ship. When people touch these large amounts of mucus, they often think it's left by monsters. If we want to study the origin of Japanese monsters, I believe that at least 70% of them come from China. However, this does not mean Inoue's view. In addition, there are all kinds of incantations, superstitions and so on, which almost make people feel that China is indeed Japan's brotherhood. When we were young, we were often warned by our elders not to whistle at night, otherwise it would attract monsters. At first glance, it sounds like a real Chinese secret. The so-called "Xiao" seems to be a wonderful whistle (scholars do not seem to know much about it), which spread to the Qing Dynasty and is said to be a kind of "voice calling for monsters".
Whistling at night also makes sense. You'd better not whistle at night!
Skills and methods of whistling
1、 External blowing pronunciation
The practice of external blowing should be carried out under the condition of peace of mind, and all the energy should be focused on the consciousness of blowing. The method is: take a deep breath, let the chest, abdominal cavity, lung more air, the better, let the tip of the tongue against the lower teeth, the middle of the whole tongue a little bulge, between the two lips naturally form an air port, maintain the status quo. Then, let the remaining gas in the body blow out slowly through the air port. At this time, should pay attention to the problem is to control the nasal cavity, do not let the air out of the nasal cavity. When blowing out, don't blow quickly. After blowing out slowly, inhale and blow again. The above is the method of blowing the remaining gas out of the body to make a whistling sound, so it is called "external blowing pronunciation method".
At the beginning of practicing the pronunciation of blowing out, you often can't make a sound. It doesn't matter. It's hard for beginners to blow at the beginning. After the completion of one blow, the next time, repeated practice, slowly can blow out a sound whistling. In this way, through the human auditory organs, the sound is transmitted to the brain. After the brain receives this signal, it quickly finds the sense of exertion of the mouth muscle and gradually shapes the mouth muscle.
（1） Breath application in the practice of external blowing pronunciation
(1) After inspiration, the diaphragm rises, the abdominal muscles contract, the chest muscles are fixed, the air mouth is closed, and the air in the lung is slowly pressed to the mouth. In this way, a kind of pressure is formed in the oral cavity, which is called 'oral pressure'. When the oral pressure is greater than the external atmospheric pressure, the breath in the mouth will automatically exhale through the air port. When the breath blows out, carefully adjust the air port between the upper and lower lips to make it sound.
(2) The volume is directly proportional to the flow of breath. The higher the air flow is, the higher the volume is; the smaller the air flow is, the lower the volume is. The volume is inversely proportional to the air port. The larger the air port is, the lower the volume is; the smaller the air port is, the higher the volume is.
（2） Volume practice
Volume is the life of Whistle Music. If you want to make a bright and mellow whistle, you must practice volume.
There are two ways to practice volume;
(1) Up to the maximum volume. After blowing, keep it up. Consciously control diaphragmatic and abdominal muscles, and let the air flow supply to the oral cavity at a uniform speed. After practicing the resonance induction of brain, hearing, mouth, nose and other organs, I feel that the sound is smooth and resonant.
(2) The sound changes from small to big and then to small. The sound is first blown in a low voice and gradually becomes larger. When it reaches the maximum, it should be kept for a period of time. Recently, until the sound disappears, it is a bit like the sound of a fire engine.
For beginners, after a few months of basic practice, they can play some small songs that they know. One is to increase the fun of whistling for learners, and the other is to let the learners' brain receive the feeling of whistling music. This kind of slow practice is very necessary. Through this kind of practice, beginners will unconsciously master some whistling techniques.
2、 Endophonation
The practice of internal absorption should also be carried out under the condition of peace of mind, and all the energy should be focused on the process of whistling. The method is: take a deep breath and let the less gas in your body, the better. Let the tip of the tongue against the lower teeth, the middle part of the whole tongue is slightly bulging, and an air port is naturally formed between the two lips to maintain the status quo. Then, the external gas is slowly inhaled into the body through the air port. Do not inhale fast, must be controlled to make the diaphragm sink, chest, abdominal muscle expansion, slowly inhale the gas into the body. After one inhalation, exhale and inhale again. This kind of method of breathing in the human body through the close cooperation of related organs is called 'internal breathing pronunciation'
It is very convenient for the player to play all kinds of music because of the combination of internal suction and external blowing. Just like playing the violin, we should not only use the upper bow, but also use the lower bow, which is very convenient for the performance of music. Therefore, if you want to be a comprehensive Whistler, you'd better grasp the internal suction pronunciation method.
There is something in common between the two methods, that is, the resonance feeling, the shape of the mouth and the position of the tongue are the same. The difference is that the external blowing is the process of blowing air into the body, while the internal breathing is the process of breathing air into the body. The more close the timbre, the better.
