The Bel Canto and the epiglottis

The Bel Canto refers to the Italian originated vocal style which became known through the singing of opera.
I’ve investigated the status of the larynx when an individual is singing the Bel Canto.
I’ve compared a Bel Canto singer with non-Bel Canto singer, by reviewing their separate performances on recorded videos. My opinions about the Bel Canto performance are as follows:
(1)I never got tired or lost interest during the performance, even when I listened to their singing for a long time.
(2)There is no awkwardness observed when the performer sang high pitched tones.
(3)The voice sounded completely natural.
The results were the opposite when I reviewed the non-Bel Canto vocalist.

I’ve figured out how ‘vitally important’ having control of the epiglottis is, after I investigated the extrinsic larynx of an individual who has mastered the Bel Canto.

The epiglottis’ lid (the opening and closing mechanism) is made by the cartilage which sends food and/or drink to the esophagus.
The orange line is the epiglottis in the figure below.

You can see the thyroid cartilage and the epiglottis in the above figures.
The epiglottis is covered by the mucosa tissues in the larynx and is controlled by the thyroepiglottic muscle.
The thyroepiglottic muscle pulls down the epiglottis to stand vertically.

Next, I’ll explain how the epiglottis moves, exactly.
Its movements are primarily only made when eating or drinking. When you swallow the food, the thyroid cartilage moves forward and collapses at same time.

The following movie mentions how to move the epiglottis when people are swallowing jelly. As the video showed, when the jelly passed through the throat the epiglottis began to collapse.


If you let out the voice when the epiglottis is standing vertically, the bronchi, the glottis, the piriform recess, the pharynx and the nasal cavity align in the vocal tract, then the voice can expel swiftly. In my opinion the above process is the best for vocalization.
You need to have good muscle condition to be able to stand the epiglottis vertically.

Note1:The Bel Canto is originally utilized for singing in the style of opera. Commonly there is no need to sing Pop or Rock music in this style, but… Bel Canto can and should be used for vocal training to assist in creating depth in the voice.
Note2:Although it’s possible to have the right condition to vocalize the Bel Canto, it maybe difficult to control when singing. This is because it is not easy to control the epiglottis on purpose as well as accurately.
Note3:Please note that if the hyoid bone gets in deep, the epiglottis cannot stand vertically because the hyoid bone blocks the epiglottis’ ability to move freely.
