In fact, the sound has its scientific rationale ahead of it. First of all, the voice of our people is front, especially Chinese. We sound natural and kind. Almost no one speaks normally when the voice is normal. Unless those who have learned vocal music and whose sound concept is wrong, they speak up to make a tone, and they sound very uncomfortable.
Secondly, the sound in front has its physiological reasons. After singing, the tongue will be retracted under normal circumstances, which will cause the laryngeal muscles to retract. The sound is actually a kind of sound flow. After the sound comes out, it has to be sent out. This is in line with the physiological law. If the sound flow has reached the throat, going back, it may form a reflow of the sound stream, the whole nest will be inside, how the sound will be transmitted, so many students who learn bad vocal music have a deep-rooted concept in their minds. It seems that singing like this is a beautiful voice. If you sing like this, you will sing something wrong in the long run, and it does not conform to the laws of physiology.
Moreover, the sound always has its physical laws. We all know that the sound is to be transmitted, but where is it passed? Obviously it is forward to pass, the more the sound stream is sent out, the more it will impact the outside air, then the penetrating power will be stronger. Singing is for the audience to listen to. Therefore, the sound is of course passed to the audience. Who has seen the audience sitting behind them? Do we have to face the audience when we sing, and pass through when we pass back? Obviously, it should be that the voice is transmitted forward, and the farther it is transmitted, the more clearly the audience hears. This truth should be well known. Welcome to the home theater network shopping guide network.
The sound is a stream of sound, which produces a chest resonance through the chest. The mouth will resonate through the mouth, and finally the sound will reach the head cavity, resulting in resonance of the head cavity. All the sound streams, in order to be transmitted, must be like a touch, from bottom to top, touching the chest, touching the mouth, touching the head cavity, when the throat passes, the pharyngeal cavity does not vibrate. All of this is done in front, there is no reason to put the sound behind. The reason why students are afraid to sing forward is that they are afraid of pale voice. In fact, pale is not wrong in itself. The mistake is not to put the sound stream on a suitable channel. If the sound stream is placed on a suitable channel, the sound will definitely not be like this. . And the sound is so textured, the sound will be pure and clean. And the penetration is very good and spreads far.
It is very difficult to do this step, so we have to lay the foundation since we were young. The basics mentioned in the usual way are the basis of hitting the sound zone. Under the circumstances of the ability, in the case of natural volume, sing comfortably, and gradually adjust the cavity in the case of whitish sound. The channel is gradually elongated on the basis of the natural sound on the front, so that the sound is not very white. Here, it must be a natural sound, don't send it backwards. What we want is the specific feeling of the vibration of the sound stream in our body. Let the sound flow touch the chest, and we will feel the chest resonance. Don't be hard, we must sing the habit of gently singing the chest for the good singing of the high notes in the future. As the sound increases, the sound stream is gradually elongated. The higher the sound, the longer the sound stream, the longer the sound stream, the better the channel, and the longer the channel. The external phenomenon of the channel extension is the lowering of the throat, the opening of the mouth, and the elongation of the sound flow. When the sound flow is elongated, remember that the sound flow is still gently touching the chest, just the sound. The flow has reached the mouth, try to reach the hard mouth cover. Often many people are in this part, let the sound flow turn and turn to the back. In fact, the sound flow we imagine should be straight up and down. Your feelings at this time, do not make adjustments, fear is to adjust later, in this case, the sound will change, it will be stuffy.
The following is the so-called sound change zone. In fact, when everyone sings a high voice, the vocal cords will unconsciously become thinner and shorter. In this case, we must always insist on the feeling of gentle touch, try to feel the high-pitched treble, when you feel that you are not working, you will not add extra strength, if you have In the power, the vocal cords will not work very well, so you have to give him freedom and can't hold it down. As the sound is elongated, our cavity will stretch longer because it is a high-pitched area and the cavity should fit well. The mouth must be large at this time, let the cavity flow with the sound to the brain, and the head of the high position in front of it will come.
In this gentle training sound stream, the vocal cords are like rubber bands, and they are toughened and exercised. In this process, I always insist on singing with the feeling of tightness and tightness. What we want is the ability of the vocal band to sing the high-pitched area. If it is avoided, the texture of the sound will be gone, and the high-pitched sound will be weak. The solid treble must come from a solid vocal cord. False sounds are not desirable.
The above is probably the process of vocal training, of course, not comprehensive, just a rough. The above practice process always adheres to the gentle flowing atmosphere and produces a vibrating sound stream. The open voice is the result of this idea. Only the open voice will have penetrating power, and the words will be clear, and will be clearly transmitted to the audience. Why is it that some sings of sings are unclear? After all, the word is unclear, so the audience can only hear the sound when listening, but can’t hear the words, sing a song and don’t know what it’s singing. It’s no wonder that the audience doesn’t like the sound. Singing.
So vocal music is not mysterious, it just complicates it.
Here are some descriptive terminology explanations that I hope will be easier for you to understand:
Just like everyone's voice is different, the sound effect of audio playback is not the same. We often use different words to describe human voices, such as harsh, hoarse, honest, magnificent, magnetic, sharp, sweet, soft... In fact, the sound quality of the sound is more complicated, sometimes you can't even find the right words. describe. "Video and New Life" Xiaobian specially compiled the contents of some sound quality tastings to share with you.
The purity of the sound <br> As we all know, the audio equipment can not reproduce the sound quality of the original instrument, in addition to the influence of many factors in the process of multiple conversions, it will also be affected by the rendering of the equipment itself. For example, a speaker box made of plastic will add plastic sound to the playback sound; the chassis made of aluminum, copper and iron will also have different metal sounds; and various different parts, such as crystals, Vacuum tubes, capacitors, resistors, etc., will also produce different sound quality, which will penetrate into the playback sound; the noise generated by the poor quality of the parts will also make the sounds have impurities.
It is impossible to make the sound quality completely pure. The efforts of the designers are often to make the sound quality as little as possible to be rendered by the equipment, and at the same time meet the public's listening preferences.
The thickness of the sound <br> refers to the sound is rough and meticulous. Musical instruments should have a moderately rough feel, and the thickness of each instrument is different. If the sound exceeds the fineness of the original instrument (due to insufficient analysis of the sound), it will lose the instrument. The texture, and sometimes the sound is not lively; if the sound exceeds the rough texture that the instrument itself should have, the sound that sounds will be harsh. Therefore, the delicate and vivid sound quality is our goal.
The Q degree of sound quality <br> The Q degree here can be understood as the sound quality is elastic, can be understood as the tail rhyme, it can also be said that the damping is moderately resonant. In fact, in music, flexibility is omnipresent and does not necessarily mean only the bass part. A good sound, whether it is bass, midrange or treble, should be flexible, but the part that affects the elasticity of the entire range is mainly low frequency.
If the sound equipment does not control the low frequency, the low frequency is often soft, loose, dragged, or has no tail rhyme; if the low frequency is too much, the ending is too fast, too short, or even no aftertaste, then The details of the low frequency will not be fully expressed. A good low frequency should be elastic, and the sound will have a tail rhyme. It will pop up and retract like a spring, and it has toughness.
The density of the sound quality <br> The density of the sound is not as tight as possible, but the density is not enough, the sound will be sparse, scattered, fat, not enough. Based on experience, many enthusiasts have the perception that the density of sound varies from device to device at different frequencies, so it must be compared to the density of the three items: treble, midrange, and bass.
Dull: This kind of sound is generated by the frequency of about 20Hz, and when it is higher than 80Hz, the sound will be thicker, so the sound with dullness is generally low, and there are few rich harmonic components. The instrumental source of the perceptual characteristics is generally the bass area of ​​the bass instrument.
Heavy: From the sound point of view, the heavy feeling is the unique sound effect at the 80Hz frequency point, and from the sound pattern characteristics, the short bass percussion type musical instrument has a stronger sense of heavy feeling.
Low: Low is often used to describe a slightly richer sound, its fundamental frequency may be the same as a dull sound, but its high harmonics are mostly richer than dull sound.
Deep: This is a kind of emotional description, often used to express the color of the "loose" low frequency response, its fundamental frequency is slightly higher than the low sound. Generally with deep sense of the instrument, the most typical is the cello and the bass area.
Void: refers to a dull sound with a "staining" effect, which is often used to describe the sound of a big wooden fish.
Thickness: This kind of sound is a characteristic of a wide-spectrum sound source, so the thick sound is generally a sound source with a low fundamental frequency and a wide spectrum.
Thickness: Thickness refers to the low-frequency sound with high integration, and the typical sound source with a thick sense is the low-range of the celesta.
Plump: This is the sound characteristic of the sound source with a frequency between 100-250Hz. Generally speaking, the sound source in this frequency band will have rich sound effects.
Generosity: If the spectrum is wider, a richer sound will be produced.
Full: This is a kind of low-frequency sound called strongness. Generally, the electric bass with "vortex distortion" effect is added. This sound characteristic is very obvious.
Bright: Generally, when the fundamental frequency of the music is higher than 500Hz, it will become brighter, even when it is as high as 7500Hz, it can also have a bright sense, so the brightness of the sound source is a relatively general adjective. The brightness is most noticeable at 2800 Hz.
Loud: It is often used to describe a high-definition sound with a neck, but when the spectrum is higher than 4000 Hz, the sound source does not have this pitch characteristic.
Hongliang: Highly bright sound with a certain fusion.
Rounded: refers to a softer, high-brightness sound.
Glimmer: refers to a high roundness sound with a certain sense of standing.
Soft: Compared with roundness, the softness is more dull and is a relatively low-brightness sound.
Crisp: The sound spectrum is concentrated between 4000-8000Hz, which generally has a certain crisp effect.
Sorghum: refers to the high-penetration crisp sound, and the typical instrument with this phonological feature is 唢å‘.
Sharp: The sound of the spectrum concentrated around 6800 Hz is generally sharp and harsh.
Sharp and sharp: If you have a sharp sound with a similar distortion, you can produce a sharp sound effect.
Slim: Music with a spectrum above 8000 Hz generally has a slender sound effect.
Fusion: Soft sounds that are generally difficult to highlight have a certain sense of integration. Of course, all sources can be measured by the degree of fusion or non-fusion. In musical instruments, it is generally believed that the viola and cello have the best sense of fusion.
Cognac: This is an antonym of fusion. The high-frequency sounds that are generally lacking in harmonics/dissonance and overtones have some degree of dryness. In musical instruments, this is mainly caused by the lack of resonance in extremely high-pitched areas.
Solid: A narrow-band sound system of around 600 Hz, and a short-sounding sound pattern, all have a solid sound effect.
Warmth: This is a word that describes the color of the music. He is generally proportional to the "staining degree" of the sound, such as the clock.
Rough: If the low-frequency sound has an effect similar to overload distortion, it can form a rough sound.
Rough: Roughness is a rough sound with a slight sand sound. Generally, the trumpet and the horn have this vocal characteristic when playing the bass zone.
Vigorous: This is a kind of emotional description, generally refers to the hoarse sound in the lower frequency band, such as the bass area of ​​the big tube.
Hoarse: Specially made with a false "sound" sound effect.
Tension: This is the result of some special discordant overtones in the music.
The sense of strength: the sense of strength in the low frequency band specifically refers to the sound in the 200-500Hz frequency band, such as the bass area of ​​Dagu and Dahu, the sense of strength is better. In the middle and high frequency bands, the sense of strength refers to the high-penetration, high-protrusion, soft-sounding sound. In the middle and high-pitched areas of the general high-pitched brass instruments, they have a good sense of strength.
Penetration: refers to the high-protrusion, high-brightness sound, the penetration is more obvious around 4500 Hz.
Sadness: Despair and warmth are anti-sense, and it is also a kind of emotional description. The typical instrument sound source with this phonological feature is the midrange of the midrange oboe.
Gloomy: High-tension low-range sound can form a gloomy sound effect.
Flat: This is the sound effect unique to the 2500Hz. Music near this frequency point is generally obviously "flat" feeling. Such as Banhu, Erhu and so on. .
Darkening: If the music component lacks more than 6000 Hz in the music, it can generally make its pronunciation "dark".
Deficiency: This is caused by the increase in noise when the instrument is at a higher scale. This noise is usually similar to the airflow.
Specifically from different frequency bands:
Extremely high frequency (Hz):
16K-20K color enhancement has a mystery;
12K-16K high frequency overtone, brilliance;
10K-12K high frequency overtone, glossy;
High frequency and high frequency low range (Hz):
8K-10K S sound (one of the B-Box basic three-tone);
6K-8K Brightness, transparency, lifting tooth tone, falling sound bleak;
The clarity of the 5K-6K language improves sharpness and fatigue;
Upper frequency band (Hz):
The surface loudness of the 4K-5K instrument enhances the distance between the instrument and the instrument;
4K penetration, enhance cough;
2K-3K is most sensitive to brightness, which makes the sound hard and unnatural;
Intermediate frequency (Hz):
1K-2K has a sense of transparency and smoothness, and has a sense of jumping and loose landing;
800 strength to increase the weight of the throat;
500-1K vocal pitch and sound profile, enhance the voice lordosis, landing voice contraction;
300-500 voice main sound zone, enhance voice monotonous, drop voice hole;
Medium frequency low section (Hz):
150-300 The intensity of the sound, the strength of the male voice, the sound is hard, no features, soft and floating;
Low frequency (Hz):
100-150 fullness, lifting turbidity, falling thin;
60-100 浑 感 , , , , , , , , , , , , , , , , , , , , , , , , ,
