The resonance of the subglottis

Some vocal coaches say that, ”the resonance of the subglottis is important for vocalizing.”
When vocalizing, the voice is the sound, and the sound is the compression wave of air. The compression wave of air refers to the vibration and movement of air.
The vibration of air makes the eardrum vibrate in your ear. The brain recognizes this sound through the auditory nerve.
The action of exhalation, vibrates the vocal cords to make the vibration of air to be added the tone or resonance in the resonance chamber. Finally, it reaches to your eardrum as the voice.
However, the vibration of air is not made in the subglottis. This is because the subglottis is underneath the vocal cord, which it why it is not added the tone or resonance.
The subglottis deeply relates and affects exhalation. If the airflow is not stable in the subglottis it will impact the the vocal chords’ ability to vibrate. Therefor, If you take a breath correctly, you can vibrate the vocal chord effectively.


Absolute vocalization

‘Absolute pitch’ is a rare auditory phenomenon characterized by the ability of a person to identify or re-create a given musical note without the benefit of a reference tone.
‘Absolute vocalization’ is the ability of person to be able to let out their voice with the perfect pitch, as well as the sound having strength and tone.
Absolute vocalization is an inherent ability. To be successful at such an ability, one must also have an excellent skill to be able to listen and focus on the music correctly.
Of course, if a person cannot listen to the sound correctly, then they cannot let out their voice correctly to mimic the sound.
If I listen a person’s singing, at first hearing them I may feel their singing sounds very good. But… if I listen over and over again, and really analyze their voice, I often notice and feel their voice is like a robot. With such characteristics as: not impressive, expressionless, boring, or just not holding their audience’s attention.
I sometimes see Professional Singers who tell me they aim and strive to be able to display absolute vocalization. I believe such a goal is great to an extent. If you want audiences to be impressed by your voice, too perfect is not good. This is because most people like the characteristics of a human emotional voice better than an empty mechanical voice.

Understanding the potential of a voice and having outside opinions of it from vocal coaches or any casual audience, will help any Singer grow and improve their singing skills.

Enjoy more singing!

Note:Japanese singers especially tend to seek absolute vocalization more than overseas singers. As a result, they tense up their throat when they start singing.
