Mixed voice! The solution of a mystery…

When comparing vocal chords to a music instrumental, the shared goal is to make sound and control/change the pitch of the sound .
The important thing is that the sound is just a fundamental tone, not producing an alluring voice or beautiful high notes.
For example, If you only pick the strings of a a guitar without the body, it would sound so small and poor. But, you can change the small/poor sound by using the hollow space of the body to be able to create an echo and produce an overtone of sound.
Take that concept, and apply it to the human voice, this is the resonance chamber. And it is composed of :                                                                       1.laryngeal ventricle 2.piriform recess 3.pharyngeal cavity 4.oral cavity 5.nasal cavity
There are some people who think that the chest and belly are also resonance chambers but that is not a fact. The reason is, because the voice expels the sound and the sound is created through a vibration of air.
The air (exhaled) is made by picking the vocal chord. Never get in chest or the abdominal cavity(of course not!) Again, this is only the path for the air inhaled and exhaled.
If you feel a resonance in chest,abdominal, head,shoulder,knee or elbow, I think that’s vibration but not resonance.
Previously,some vocal coach believed that the sound come from knee of elbow.
It’s probably possible to feel that the organ which is near by the vocal tract vibrates but I wonder whether knee and elbow also resonate or not.
Let talk more about the structure of vocal chord.
I think what I can get some idea about good voice and singing.
I talked about the cross of the vocal chords before: click here link
If I sketch out the role of good voice or singing to require for vocal chord as fundamental tone,that is the natural voice ,falsetto and mix voice.
It does not include tone color such as beautiful voice because the tone is made in resonance chambers.
By the way, what is the natural voice ,falsetto and mix voice?
I tested before,and I asked young great mimic who copied a bunch of voices which were chosen by me, and ask them(who is singer,voice actor,actor,people have no interest in voice)to listen his voice.
Which one do you think natural ,falsetto or mix voice?
As a result, surprisingly every answer was different…
Especially about sensitive mix voice, elite singer even could not figure out which is exact one
such as ”This voice is mix voice but close to natural voice” ”no,close to falsetto” ”no,exact falsetto” ,i.e….
Therefore, there is no exact definition.
How natural ,falsetto and mix voice is generated?
If you know this correctly,you can understand why every voice sounded different for everyone.
I mentioned that the natural voice is made by vibrating the vocal mucosa and muscle, falsetto is made by only vibrating vocal mucosa, and mix voice is made by changing the hardness of vocal muscle and the vibration rate so far. This is rough explanation and let me explain more detail.
It’s easy to know what happens on the natural voice,and the muscle is weighty, and if the whole muscle can vibrate correctly, it makes the clear voice.
In the case of falsetto voice, the part of vocal mucosa outside the vocal ligament only vibrates.
This means that’s stratified squamous non-keratinizing epithelium and Reinke’s space.
Be aware of two things about this.
How does the muscle move during singing falsetto?
I’ve looked into the status of vocal chord through the fiber scope before when producing the natural,falsetto,mix,edge,whistle or death voice and so on.
In the case of falsetto voice,I did not see any vibration on vocal muscle,which is far from glottis because the muscle is rigid.
The vocal muscle is the skeletal muscle but not visceral muscle, which moves involuntarily.
The skeletal muscle has some features. It shrinks and gets rigid,and this mechanism makes the falsetto voice.
I know that someone cannot come out the falsetto due to the rigid vocal muscle by constitution.
Next one is that the vibration changes depends on the status of loose connective tissue in Reinke’s space.
There is collagen fiber relating to the hyaluronan and the collagen in Reinke’s space.
The loose connective tissue bears the nonkeratinized stratified squamous epithlium which has a lot of fluid element. That’s why,the vibration is changed by gel.
If this fluid becomes less,the vocal fold contracts, hard to make falsetto or cases the vocal cord atrophy in the worst case.
The peoples who had the vocal cord atrophy have improved partially by hyaluronic acid injection before.
The last is talking about mix voice!
The point is what you give the vocal muscle flexibility and power,moisturize the vocal muscle if I roughly talk about how to control the hardness of vocal muscle and moisturize the vocal fold,and it’s important that is the vocal ligament and the elastic cone,ligament generally bonds between bones.
The vocal ligament bonds the processus vocalis cartilaginis arytenoidei and anterior commissure of thyroid cartilage,this does not make the arthroplasty for indented usage. The larynx is really unclear part in human body.
The vocal ligament also has a big roll with the arytenoid cartilage rotating and sliding.
The vocal ligament is required to provide plenty of support the vocal muscle for getting move better,and there is the elastic cone between the vocal ligament and the arch of cricoid cartilage.
This means that the elastic cone also supports the vocal ligament.
If the vocal ligament and the elastic cone are not steady,that degrades the motion performance of vocal muscle.
Furthermore, it would be a waste not to use the elastic cone, this connects to vocal fold closely.
If you could make it suitable vibration,you can make a wider sound.
After I tried using the artificial arytenoid cartilage and cricoid cartilage which made by paper clay, I’ve figured out the relation between the movement of the vocal muscle,the vocal ligament and the elastic cone.
Although, this is still during the experiment and hypothesis, I’m willing to continue investigating this.
The people is good at using mix voice who sounds really good singing.
Note:The hardness of vocal muscle is changed by muscular excitation and relaxation, expansion and contraction by moving the arytenoid cartilage and blood pressure change(not disease),and the above 3 points.
