The Phenomenon of hypertonic phonation or LDP

If you feel choking or if it’s becoming hard to let out your voice, commonly at the halfway point of singing a song, then you are suspected to have hypertonic phonation or LDP (Larynx Deep Position).
This is not relating to the skill of singing. This issue is relating to the muscles of the throat. The muscles become stiff and in turn, cause the larynx move into a deeper than normal position.
This is a muscle habit which adversely affects singing.
It is better to treat this condition in the early stages of discovery. When gone untreated can cause more, depending on the degree, or even permanent damage to the throat’s muscles.

Note: Hypertonic phonation, as mentioned above, is not a disease. It is a treatable condition.

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.

Our breath has a tone

Although I cannot say for sure that it is a completely easily distinguishable tone, but yes – our breath has ‘a tone!’
I tested this theory, using a recorder.
The findings are as follows:
I selected a testing group and asked each person to play the same melody using a recorder. When comparing the playback recorded sounds, I found that even though each test subject used the same instrument and played the same melody, every tone varied with each individual.
As a result, it can be determined that the breath has a tone.
Breath comes out from the body passing through the lungs, the bronchi, the glottis, the laryngeal ventricle, the piriform recess, the pharynx and the oral cavity.
Exhaled air is different with each person, depending on the body’s varied qualities of the above tissues such as shape, size, length, weight, hardness or angle.
These differences affect the tone of our breath when blowing into the recorder.
The main factors that influence voice tone production are not only the five resonance chambers, but also exhaled air.
It’s true – in all over the world, no one has the same voice.

The reason why a person’s sneeze can sometimes sound so loud

Have you ever been surprised to hear a really loud sneeze in a public place such as when walking on the street, shopping, riding the train or at the office?
The sneeze noise is referenced to as ‘Haku-Syon’ in Japanese and ‘Achoo’ in English. In my opinion, the Japanese sneezing noise makes a louder sound due to its pronunciation length, compared to the English noise.
The action of sneezing is a corneal reflex, for ridding the body of foreign substances or thermoregulation.
The breath and movement of the larynx muscle plays a very important role in controlling the volume of an individual’s sneeze. This is because sneezing is an involuntary movement.
However, if these muscles deteriorate, the sneeze noise tends to be louder than usual because the muscles can’t be controlled well.

LDP….Some professionals can fix LDP, and others cannot

If you have any of the following problems with your throat it is best to first go to an ‘Otological Doctor’ or a ‘Voice Care Specialist.’ Such as a feel of choking, difficulty in letting out the voice, if your throat makes abnormal noises when drinking water, if your voice sounds boxy or it’s generally hard to let out any kind of high register tone.
If a Doctor cannot detect any specific problem or fix your throat after taking treatment, you possibly have LDP.
LDP.
L.D.P. stands for ‘Larynx in a Deep Position.’ It is a muscle habit. When the muscles relating to vocalization become stiff and the larynx is positioned in deeper than normal position. LDP is not a disease, it is a condition.

I use these following methods to treat LDP;
1.Tugging and stretching the throat muscles (to relax the muscles and give it flexibility)
2.Ultrasonic treatment targeting the throat muscles
3.Ultrasonic treatment targeting the muscles relating to vocalization
4.Infrared therapy for improving motion performance of the throat
5.Microcurrent treatment for the throat muscles
6.Low-frequency therapy for improving muscles relating to vocalization
7.Red LED therapy for improving the blood circulation of the superior laryngeal artery
8.Electric needles specifically for improving the blood circulation of the middle constrictor
9.Regular breathing training
10.Pressure breathing training
11.Pulling out the hyoid bone
12. Mobilization of the cricothyroid articulation.
13.Training to improve utterance and the common stutter
14.Weight training of the cricothyroid muscle

I give a lot of treatments individually depending on each individual’s condition.
However, I never know exactly how long it takes to fix LDP completely, because every condition’s degree varies. Persistence, dedication, and continuity are always needed from both the individual and the professional treating the issue for the outcome to be successful.

How I diagnose LDP                                                                                         (1) The throat makes abnormal sounds, when the thyroid cartilage is moved      from side to side without pushing                                                                     (2) I can see the omohyoid muscle going up when letting out the voice               (3) Measurement, when using a muscle hardness meter, is more than 30Tone.

Some people have all three of the above issues, others may only have one of the three, and rarely there is an extremely critical condition of LDP.
Some people can be fixed only after a couple times of treatments, and others cannot be fixed even after treatment for more than a couple years. Many patients give up hope when lengthy treatments take too long. When beginning treatment it is important to be familiar with the condition, the treatment procedures, have a positive outlook, and be committed to a treatment schedule.

Note:I have treated thousands of patients who have LDP.
From this experience, I have found that the following types of individuals can fix LDP quickly when they:
1.Take treatment very often within a short time frame
2.Feel serious, eager and want to fix LDP
3.Take voice care candy daily
4.Understand the basic mechanics of vocalization
5.Often enjoy singing or music
6.Have an active lifestyle or are athletic in currently playing or used to do sports before

An unsuited throat for singing

Unfortunately, if the incisura of the thyroid cartilage is really visible, then that individual’s throat may not be suited for singing.

When the incisura of thyroid cartilage is visible, the thyroid cartilage and cricoid cartilage lean forward, causing (Larynx Deep Position) LDP. Noticeable symptoms would be feeling a lump, choking and/or coughing in your throat which absolutely obstructs singing.
Even if you do not have LDP, (in regards to the cricoid cartilage) if the cricothyroid articulation cannot move wide enough, as shown in the drawing below, it is difficult to let out a high and low pitched voice.
