Is it true that even if you catch a cold, it is still easy to sing falsetto?

I got this question from a singer who has shown a great kinematic performance of the larynx:
Is it true that even if you catch a cold, it is still easy to sing with falsetto?
I thought, that is a really good question!
The answer is yes, the falsetto is displayed when the thin mucosa of the vocal chord mainly vibrates. Where as the original voice is displayed when the vocal cord muscles and mucosa vibrate together.
If you catch a cold, the vocal chord is swollen due to inflammation, maybe you’ve seen the red intrinsic larynx by observing visually or in a hospital, this is referred to as hyperemia.
The hyperemia is when a blood capillary explodes and the blood vessel gets closed.
The hyperemia weighs down the vocal chord, the vocal chord then swells. The heavier weight from being swollen produces a lower pitch than normal.
Furthermore, it becomes harder to control voice pitch, and the throat is more inept to get dry. Mainly because the blood vessel is closed and in turn creates a reduced flow of blood through the bloodstream.
Additionally, increased viscoelasticity of the mucus will occur, and is usually accompanied by sputum in the back of throat. The voice will sound noticeably shattered or gravelly, because when the glottis opens breath is leaked out.
But, what if you experience barely being able to sing with falsetto?
Cold strains do vary. The mucosa has no blood capillary and is sometimes not affected by the hyperemia. Therefore, it is true that even if you catch a cold, it is still easy to sing falsetto.
Of course, the sound quality will vary when you have a cold.
Please be careful not to catch a cold.
Common colds often cause the larynx to become swollen inside, similar to a musician pouring water over their instrument. What happens is that the wooden parts will absorb the water and will not be able to be played properly.



What is the identity of an attractive voice? –Important–

This a is very important overview.
Don’t you think a good voice is determined by the vocal chords?
Actually, a vocal chord mainly creates the sound source and pitch, not quality or resonance.
Vibrations made from the vocal cords’ mucosa and vocal cord muscles are used in concurrence to create the sound source,
The pitch is made by using the length, thickness and hardness of a vocal chord, combined with breath, this is referred to as an “interval”.
So, how is quality and resonance made?
The answer is the resonance chamber.
The resonance chamber can be compared to the strings of an instrument. The quality of sound that the strings produce can be compared to vocal chord strength and movement control. The resonance chamber can be compared to the body of a music instrument.
You can imagine that if you play the strings without body, it does not have a nice ring and makes a weak sound.
The Stradivarius, which is highly prized violin, is of utmost value on its body but not strings.
Therefore, the identity of attractive voice is obviously from the resonance chamber.
Regarding the resonance chamber in people is that
“1:laryngeal ventricle 2: piriform recess 3:pharyngeal cavity 4:oral cavity 5:nasal cavity”(it’s order in closeness, from the vocal chord)
Everything is important but the pharyngeal cavity which which is located behind the hyoid bone is the most relevant chamber to sound quality.
When you change the size or figure of the pharyngeal cavity, which is composed of the soft tissue, the sound quality changes dramatically.
This fact is why, the voice has more tone color and range than a music instrument.
Furthermore,the epiglottis which is a very important part for the bel canto is also in the pharyngeal cavity.
I definitely would like you to practice and learn to control the pharyngeal cavity and the vocal chord well.

Woman Face

Note1:Beside the pharyngeal cavity, are the lips. Which also play a major role in making the tone colorful and tuning. Practice not touching your lips to the tooth surface or gums too much while singing.

Note2:Let’s compare the pharyngeal cavity to musical instruments ranging in different sizes, but can still produce the same strength in volume and pitch. For example, a wooden soprano recorder which is small and thin compared to a metal euphonium which is big.
It’s possible to change the pharyngeal cavity similar to this aspect, because human soft tissue can freely change in size and hardness.
The hyoid bone is located in the back, it has very minor bearing on tone or color changes.
That’s why, it is very important to focus on the strength and quality of the muscles around your larynx.
