Edge voice and Death voice

I’ll explain how to make an edge voice and a death voice.
To make the edge voice, the arytenoid cartilage on the cricoid cartilage moves. This movement is a slide and tilt to the side, and the vocal folds bend down to make a space between the glottis.
Furthermore, if you exhale stronger when extending the vocal cords (causing the mucosa) downward, from the status of making the edge voice, then the death voice will be made.


Note1:The vocal folds move downward when letting out both the edge voice and death voice. If you exhale to vibrate the vocal folds when the vocal folds are downward, the vibration increases making the edge or the death voice. 
This is same as with a guitar, if the strings are thin it makes high-pitched sounds, and if strings are thick it makes low-pitched sounds. If you tighten the strings the guitar will make a high-pitched sound, and if you loosen the strings, it will make a low-pitched sound.
Similarly, the vocal folds’ pitch is controlled by (1)opening and closing (2)expansion and contraction (3)hardness and softness (4)thickness and thinness.

Note2:In the case of human beings, structural composition is always different and depends on the person’s (1)angle (2)size(3)speed(4)asymmetry
In conclusion that is why everybody has different abilities and every individual’s voice is unique.


Issues relating to asymmetry of the vocal folds

If you go to the Otological Hospital and the Doctor says that there is no problem with your throat, but you are suffering from symptoms of a hoarse voice, a feeling of choking when vocalizing, or having too quiet of a voice, then please suspect LDP. LDP stands for larynx in a deep position. This issue is very difficult to see and diagnose without proper equipment. When dealing with vocal issues, LDP is the most commonly overlooked issue by Doctors.
As a voice care professional, I’ve helped a lot of people who have LDP.
However, I have come to learn that even if a patient takes a lot of treatment, improvements are slow and gradual. Regardless of the degree of improvement, LDP patient’s vocal folds will always be asymmetrical.
If the vocal cords weight is different between the right and left sides, the speed and timing of the vibrations made by exhaling are also different. Although this is a really small deterrence, these minor differences in weight or size cause a hoarse voice, a quieter than normal voice and/or a feeling of choking when vocalizing.


If you train the muscles related to vocalization, it is absolutely possible to be able to move both vocal folds evenly.
Yes, you can train and exercise your vocal muscles by yourself.
I’ll report more progress from my research findings, as well as exercises and treatment care for LDP sometime soon – Please wait for good news from me!


A common dilemma with musical pitch

A common dilemma with musical pitch is being consistent and accurate.
You can overcome such issues. If you let out the first pitch sound correctly, you can keep singing with the correct pitch consistently. When you let out the last pitch of each phrase correctly, your singing will also sound good.
In fact, most people who are not good at singing can noticeably not sing the last pitch of a phrase correctly.
Therefore, if you focus and pay close attention to singing the first and the last pitch carefully, your singing can sound great. Please try it!


Note:Generally when people move from a resting state, then stop and enter a state of motion, they are using a lot of muscles.
As the above states, vocalization also needs to use the muscles relating to vocalization so much when letting out the first voice pitch and the last voice pitch. This is because the vocal folds are vibrated by muscles using air. That air is echoed in the resonance chamber to make the voice, which finally comes out from the mouth.
Regarding the above mentioned voice training tips, please be careful with your vocal muscles and don’t practice anything excessively.
Vocalization is a sport and you are the athlete of your voice.
