How to protect
Teachers use Mike, and parents have opinions.
The teacher's voice is so low that the students sitting in the back row can't hear the teacher at all. Some students who can't hear clearly either whisper or read extracurricular books. Teachers often stop to maintain class order, which also affects the listening effect of other students. Some teachers choose to wear "Mike" in class according to their own situation, so that they don't have to lecture loudly all the time, which is conducive to fundamentally protecting the teacher's voice.
Some parents are worried that the teacher will wear "Mike" in class. A student's parents said that teachers not only spread knowledge by voice in class, but also personal charm and passion are an important part of a good class. These humanistic qualities and cultural details can not be underestimated and ignored in guiding and attracting students.
Common throat diseases
Teachers' Occupational Disease-Multiple Pharyngitis
The cause of teachers' illness is probably related to their professional factors-teachers' long-term overloaded lectures and unscientific pronunciation methods make the mucosa of the throat and pharynx suffer from congestion and swelling under the long-term impact of strong airflow, which is prone to chronic pharyngitis. Insomnia, anxiety, general malaise and other sub-health symptoms, in the view of Chinese medicine, are the dysfunction of yin and yang. Chen Ruifang said that chronic pharyngitis is not acute inflammation, and it is particularly effective compared with traditional Chinese medicine. These common problems can be solved by nourishing yin.
Experts suggest that teachers: master vocal skills and pay attention to vocal methods; When you have a sore throat and hoarseness, you should see a doctor in time; Female teachers should not use their voice excessively during menstruation; Don't smoke and drink, eat less spicy food, and get into the habit of drinking water in class. In addition, excessive alcohol and tobacco will irritate the throat, and if you have chronic rhinitis, sinusitis and other diseases with frequent nasal congestion, breathing dust with your mouth open will also cause chronic pharyngitis.
Common voice diseases are: (1) organic diseases: vocal cord congestion, vocal cord polyp and nerve paralysis; (2) Functional diseases: poor glottis closure, excessive vocal cords closure, dysphonia, cardiogenic dysphonia, vocal nodules, functional or pathological aphonia.
There are several voice diseases that usually cause hoarseness: congenital malformation of larynx, acute laryngitis, chronic laryngitis, vocal nodules and polyps, benign tumor of larynx, laryngeal cancer, laryngeal nerve paralysis and hysterical aphasia.
Use pronunciation skills
1, practice breathing and strengthen motivation.
Breathing is the kinetic energy of rap and the most basic link of vocal music practice. Daily breathing is relatively calm and shallow, and it is not necessary to use all the vital capacity, but the breathing action during rap is different, with fast inhalation and slow exhalation. When you meet a long sentence, you have to hold your breath. Changes in pitch, such as high, low, strong, weak, cadence, cadence, can only be accomplished by vigorous and flexible movements of inspiratory and expiratory muscles.
Exercise: Pronunciation skills can be improved through training.
Teachers can train breathing in two ways:
First of all, you can do some breathing training during the break. 1. Inhale: Inhale vertically downward with your mouth and nose, and suck the air to the bottom of your lungs. Be careful not to lift your shoulders. When inhaling, the lower ribs will expand. On the abdominal side, the diaphragm will gradually expand, so that the abdomen will expand forward and left and right sides, while the lower abdomen will contract without expansion. The back should be upright, and the spine should hardly move, but both sides can move, and it must be extended downward and left and right. At this point, the gas is pushed to the sides and back and stored there, held there, and then exhaled slowly. Then exhale: when you speak with your breath, keep breathing. There is also a problem of keeping breathing. To keep breathing, you must keep breathing in the process of speaking, control your breath to spit out slowly, save your breath and exhale evenly. This is called breath confrontation. In the process of breathing and inhaling, we should avoid the feeling of stiff breathing and take the initiative to relax the whole body expression. The tense part is the diaphragm and ribs, and the ribs are like a full balloon. We should let the sound sit on it and pull it down, so as not to let the balloon float, that is to say, we should hold the breath and not let it lift. This is the so-called "breath fulcrum" problem. Secondly, you can do some breathing exercises before and after class. Such as: counting gourds (gourds 1, gourds 2, gourds 3, gourds ...) (how many are you breathing in one breath), imitating "dog panting", humming practice and so on. These exercises do not affect others, but also exercise their own breathing. At the same time, they strengthen the rap function, dredge the tendons, strengthen the motivation, and create a good "working environment" for the voice.
2, using * * * Ming, rap is labor-saving. Using * * * is to let the sound supported by breath enter the * * * cavity to produce * * * sound, and the sound with * * * sound is both easy and penetrating. Let's also learn about the vocal organs of the human body. The vocal organs of human body mainly include chest, mouth and head cavity. The thoracic cavity includes trachea, bronchus and the whole lung below larynx; Oral cavity includes larynx, pharyngeal cavity and oral cavity; The head cavity includes nasal cavity, maxillary sinus, frontal sinus and sphenoid sinus. When speaking, the proportion of using these * * * cavities varies with the range, volume and pitch. Generally speaking, when using the bass zone, the chest cavity will play the greatest role when the volume is small and the sound is high or low; When the alto is used and the volume is moderate, the oral * * * sound is widely used; When using the treble zone, when the volume is high, you should mainly look at the head cavity. If we can make good use of these cavities correctly and reasonably and coordinate with each other, then we can get a mellow, pleasant, plump and beautiful sound.
* * * Humming practice is best to use humming, which is often called "humming". When practicing with "Hum", I feel a yawning state. The lips are slightly closed, the mouth is empty, the better, the nasopharyngeal cavity is open, and the breathing channel is wider, the better. Then let the breath pass through these channels smoothly and enter the sphenoid sinus of the head cavity along the pharyngeal wall and nasal cavity wall. The feeling of sphenoid sinus is the eyebrows on our foreheads. Feel the sound moving forward and upward, feel the vibration between the eyebrows, and thus make a bright and concentrated "hum" sound. If you practice this tone from bass to treble, you will feel the movement of three * * * vocals, the bass area will obviously feel the less used chest * * * vocals, the midrange area can feel the more used oral * * * vocals, and the first vocals in the treble area must be practiced. We usually use mixed voices in class. There are many ways to do a good job of mixed voice: consult a vocal music teacher; Imitate the drama actor Dao Bai; Imitate the singer's voice. In life, teachers can practice singing by learning how babies cry. A baby crying for an hour without hoarse voice is the best hint. It is our goal to speak with * * * in class and save effort to protect our voice.
3. Articulate clearly and beautify the sound. Pronunciation is the only way to circle. If you want a good voice, you have to know how to pronounce words. Speech organs (that is, language organs) include lips, tongue, teeth and palate. The position of these organs when they are active and the different parts of their efforts form consonants and vowels (that is, language). Speak more quickly and exaggeratedly than usual. Clever is to make the pronunciation accurate and clear, and exaggeration is to make the beautified vowels or vowels play smoothly. Therefore, language organs are the material basis for us to pronounce and pronounce words, and they are also important organs for us to pronounce, quote and rhyme when we learn to pronounce and pronounce words. You can train under the guidance of professional vocal music teachers to form conditioned reflex to judge whether your voice is correct or not and whether it conforms to the basic laws of vocal organ movement. It should also be pointed out that organs are only the basis of vocalization, and the coordination of these organs needs to be completed under the control of human nervous system.
Will, emotion, desire and feeling, etc. , largely related to psychological factors, sometimes psychological constraints will hinder the play of sound. Therefore, while beautifying the voice, we should carry out psychological training and pay full attention to the importance of psychology. Pay attention to the content and emotions expressed in the lecture, and be affectionate and vocal. In this way, you can speak easily and students can hear clearly and be happy.
4. Keep practicing your voice and reserve energy for your voice. Everyone wants to use interest when spending money. How can we realize the benefits? That is practice-persistent practice. Like the formation of oil and coal, it was the storage of solar energy1-200 million years ago. Practicing voice is to store the interest of voice. It is necessary to ask a vocal music teacher to practice vocal music regularly, which can not only correct the vocal problems, but also learn to use your voice scientifically and prolong your professional life. Many actors, singers and announcers practice their voices to make their voices return to normal and rejuvenate.
Modern vocal music skills are mainly based on adjusting personality and controlling emotions, taking nature and truth as the method, and aiming at pure, transparent, free and high-quality voice. There is also a saying: one side of the soil and water support one side of the people, a nation has the characteristics of a nation, a region has a regional style, and the voice varies from person to person. Different voice features pay attention to different methods, and there must be clear judgment.
How to protect
(1) Enhance the body's resistance. Exercise, pay attention to nutrition and keep your throat healthy.
(2) Unclean mouth can easily cause throat inflammation. It is necessary to develop the habit of gargling after meals and brushing your teeth before going to bed.
(3) prevent colds. Because many throat diseases are related to colds, we should pay attention to increasing or decreasing clothes to prevent catching cold; During the flu epidemic, wear a mask when going out and try to go to public places as little as possible.
(4) Eat less spicy food and avoid alcohol and tobacco, so as not to irritate the throat.
(5) Speak in moderation, don't talk loudly or talk too much, otherwise it will aggravate the fatigue of throat muscles, especially vocal cords.
