Why did you learn to sing with JJ Lin, and suddenly your voice became louder, which sounded much better? Is it because you learned from his resonance that your voice is loud?

Hello.

I * * organ and its working principle

The sound emitted by the vibration of one object propagates to other objects, causing other objects to vibrate, that is, causing * * * vibration, which is called * * * ringing.

(A) the composition of the singing organ

* * * The vocal organs include all cavities of the vocal system, including chest cavity, throat cavity, pharynx cavity, oral cavity, nasal cavity and sinus. The soft palate is divided into upper vocal cavity and lower vocal cavity. The nasal cavity, paranasal sinus and nasopharyngeal cavity are called superior sound cavity, and the chest cavity, throat cavity, pharynx cavity and oral cavity are called inferior sound cavity. When singing high notes, you mainly use the * * * cavity, and the medium and low notes mainly use the * * * cavity. According to the fixity and flexibility of the volume, each cavity can be divided into a constant cavity and a variable cavity. Thoracic cavity, nasal cavity and sinus (including frontal sinus, sphenoid sinus, sinus and honeycomb bone, etc.). ) has a fixed gap and is a constant sound cavity. The mouth can be large or small, the tongue can be long or short, it can move freely in the mouth, the muscles of the pharyngeal cavity can contract and expand, and the laryngeal organ can move up and down. The characteristics of these organs show that the oral cavity, pharyngeal cavity and laryngeal cavity are variable.

(2) The working principle of singing organ * * *

The sound just emitted from the vocal cords is weak and simple, but this weak and simple sound will become pleasing to the ear under the action of the vocal organs. Just like the horn, the bright and full transmission of the horn is due to the role of the horn. If you remove the role of the speaker, the sound will be very weak and unpleasant. So people's * * * cavity, like a bugle horn, plays a * * * role in sound. The principle of sound production is very similar to that of reed instruments. A person's throat is like the mouth of a reed instrument, and a person's vocal cords are like the reeds of a reed instrument. It is five or six inches long from throat cavity, pharynx cavity to nasal cavity, which is equivalent to a tube.

The sound comes from the vocal cords, that is, through the laryngeal cavity, laryngeal opening, pharyngeal cavity, and then through the space between oropharyngeal cavity and nasopharyngeal cavity to reach the nasal cavity. In this process, the sound is heard in the throat, pharynx, mouth and nasal cavity, and the sound is amplified. Then the amplified sound is transmitted through the skull, causing * * * vibration of several sinus bodies, thus strengthening the * * * sound, and at the same time, the sound also produces * * * vibration in the chest cavity, causing * * * sound in the chest cavity. Next, we will outline the role of each cavity in singing.

1. Chest * * *

The chest is located below the vocal cords. Including trachea, bronchus and whole lung. Some sound waves (mainly low-frequency sound waves) emitted by vocal cords can be transmitted to the chest, causing * * * to sound, giving off rich and broad timbre, and the chest has obvious vibration at this time. Chest * * * singing is generally used in bass and coarse tenor, and it is good at expressing deep and solemn feelings.

2. Pharyngeal cavity *

The pharyngeal cavity is located above the larynx that produces sound, connecting the head cavity upwards, connecting the chest cavity downwards through the throat, and being adjacent to the oral cavity outwards. The pharyngeal cavity consists of oropharyngeal cavity, pharyngeal cavity and nasopharyngeal cavity. It is the first sounding body through which sound waves must pass upwards, and it is the' connecting part' between the upper sound cavity and the lower sound cavity. When singing, the vocals produced by each vocal cavity are transmitted by the vocal cavity in coordination. Pharyngeal cavity is a variable acoustic cavity. People often experience the state of pharyngeal cavity expansion by blowing, lifting the soft palate and tightening the pharyngeal wall. The pharyngeal cavity expands to form a space. If it is properly matched with other vocal organs and used properly, it can produce bright and powerful timbre, which is helpful to express firm and decisive emotions.

3. Mouth * * *

The mouth is variable. When singing, according to the pronunciation characteristics of different vowels, the opening and closing range of the mouth can be large or small. The oral cavity not only undertakes the heavy responsibility of singing, but also undertakes the complicated and changeable task of delivering words. Therefore, in the adjustable cavity, the oral cavity has the heaviest task, the most complicated action and the more important role.

When singing, always keep the soft palate and uvula raised and the throat open, so as to ensure the smooth combination and connection of the oral cavity, pharyngeal cavity, head cavity and chest cavity, and form a whole singing. Spoken language * * * is widely used in life, which makes the voice and timbre bright and clear, and the pronunciation is friendly.

4. Nasal cavity * * *

Nasal sounds include nasal cavity, nasopharyngeal cavity and sinus. Is a constant cavity. Sound waves cause * * * vibration through the throat, pharynx, mouth and nasal cavity, and then cause * * * vibration of several sinus bodies through skull conduction, so as to enhance the sound production of * * *, which is called' bone conduction' (not air conduction).

Nasal humming is mainly realized by means of' bone conduction'. The nasal cavity * * * sound is produced on the basis of the lower * * * sound. That is to say, after the sound produces strong sound waves in the chest cavity, throat cavity and pharynx cavity, the sound waves reach the hard palate, and the vibration of the hard palate causes the sinus of the nasal cavity and head cavity to vibrate, which can not only increase the volume, but also increase the intensity of the sound. The sinus body includes frontal sinus, ethmoid sinus, frontal sinus and sphenoid sinus. Because of different regions, the bone tissue in the head cavity causes different vibrations in the nasal cavity. Generally speaking, the * * * sound of frontal sinus is the strongest and clearest, because this * * * sound area is directly vibrated by all sound waves of laryngeal cavity, pharyngeal cavity, oral cavity and nasal cavity. The nasal cavity * * * is also called the head cavity * * * because the correct nasal cavity * * * will make the singer's head vibrate and feel the sound coming from a cavity in the head. In fact, the brain itself is full of brains without cavities, and this feeling is just a kind of nasal cavity.

The nasal cavity is the most important singing style in singing, and it is a tweeter. It can make the timbre bright, soft, powerful, metallic and penetrating, and is good at expressing passionate emotions. It is often used for singing in high-pitched areas.

According to the requirements of vocal music, these * * * sounds all play a role in singing, that is, the mixed * * * sound effect. Only with the different pitch, the proportion of three * * * vocals mixed with * * * vocals is also different. For example, when singing bass, the chest is mainly singing; When singing contralto, the throat, pharynx and mouth are the main tones; When singing high notes, the head cavity is mainly singing. However, when singing, it is required that the voice should be connected up and down, and there should be an overall concept of the voice. For example, when singing alto, the main vocal areas are in the throat, pharynx and mouth, but they cannot be completely separated from the vocal functions of the head cavity and chest cavity. In singing, these vocal areas should not only have clear boundaries, but also be interrelated and become a whole.

* * * Ming Can makes the voice mellow and sweet, adjusts the pitch and changes the timbre, which is an extremely important part in singing.

Second, sing * * *

Singing * * * plays a very important role in singing art activities. The volume of singing, the quality of timbre, the clarity of words, and even the appropriateness of musical expression and emotional expression are closely related to the singing skills of * * *. In short, successful singing art activities must be based on good singing.

In singing, singing cavities communicate and coordinate with each other, so that different songs blend with each other and form a harmonious and unified whole mixed song.

(a) * * * cavity adjustment and ideal * * * effect.

The adjustment of vocal cavity mainly refers to the adjustment of the position and state of adjustable vocal cavity, that is, training to put down the larynx, relax the chin, flatten the tongue, lift the soft palate and tighten the pharyngeal wall. After adjustment, the oral cavity and pharyngeal cavity should be able to communicate with the nasal cavity, chest cavity, tooth back and pharyngeal wall. In this way, these * * * cavities always keep a large space, which is convenient for sound waves to generate * * * vibration, so as to obtain the ideal * * * sound effect. However, if the non-tunable cavity can produce good * * * effect, it must also rely on the adjustment of the tunable cavity and the transmission of * * * sound.

1. Oral cavity * * *

The oral cavity is an adjustable acoustic cavity. The oral cavity is not only responsible for the important vocal task, but also for the complicated and changeable task of articulation.

When singing, according to the pronunciation characteristics of different vowels, the opening and closing range of the mouth can be large or small. However, the core position of the oral cavity should not be too forward, and it should be moved back a little, so as to combine the oral cavity with the pharyngeal cavity, and connect the pharyngeal cavity up to the chest cavity down to get the head cavity * * * so as to get the overall * * * sound effect. If vowel [a] is pronounced, the oral state should be to lift the soft palate, close the uvula, open the mandibular joint, and naturally lower the jaw, so that the internal oral cavity will open and stand up and down, and combine with the pharyngeal cavity to form a harmonious and unified singing body. When the sound [A] is issued in this state, it will inevitably produce oral * * * sounds with the inner oral cavity as the core position. At this time, after the oral cavity * * * and the pharyngeal cavity * * * are mixed, they pass upward through the nasopharyngeal cavity to the head cavity, resulting in the head cavity * * *, and the chest cavity will be obtained by connecting the throat cavity downward.

2. Pharyngeal cavity *

The pharyngeal cavity is composed of oropharyngeal cavity, laryngopharyngeal cavity and nasopharyngeal cavity, which is located above the larynx that emits sound, connects the head cavity upwards, connects the chest cavity downwards through the throat, and is adjacent to the oral cavity outwards. When singing, the * * * voice produced by each vocal cavity is coordinated and transmitted by the pharyngeal vocal cavity. The longitudinal and orbicularis muscles in the pharyngeal cavity are used to change their length and width. Therefore, when singing, the different intensity and timbre of each voice require the pharyngeal cavity to have a specific shape, and the beautiful sound quality is also determined by the shape of the pharyngeal cavity. Therefore, the pharyngeal cavity plays a role as a bridge and hub in the singing effect of other vocal cavities, and the pharyngeal cavity * * * plays a very important role in singing * * *.

The formation of the ideal pharyngeal cavity hum mainly depends on the adjustment of the following parts.
