Jeremy. There are some interesting aspects of inspiratory hold which reinforces it's role in maintaining an open throat. It is interesting that with a proper and full inhalation of the breath, that the space between the hyoid and thyroid opens a little and that the thyroid cartilage also descends a little. What is interesting is that during inspiration the whole respiratory tract actually descends. This includes particularly the trachea and bronchi but also includes the lung root (blood vessels and major bronchi). This is because the whole bronchial tree is like an accordion, full of elastic tissue. The trachea for example with a proper breath, elongates by as much as 20% (2.5cm). The carina (at the bifurcation of the trachea into the two mainstream bronchi) also descends the same distance. The thyrohyoid membrane between the hyoid and thyroid cartilages is also made partially of elastic tissue and hence also stretches downward. Loss of inspiratory hold causes these structures to snap back to their original position along with the attendant closure of an open throat. This physiology emphasizes the importance of a full breath and the maintenance of inspiratory tension to hold the respiratory tract in this position and hence hold the opening. It means singing in the correct manner is hard work! It takes real talent to hold the opening with a low volume of breath. I believe that respiratory physiology reinforces Stanley's contention about the importance of inspiratory hold (which must be held from the 6th to 10th rib down through the torso). Also a relaxed abdominal Wall Is very important to allow for the full unimpeeded descent of the diaphragm. While one must pay attention to registration and to proper positioning of the resonator, neither of these can function properly without the proper degree of inspiratory hold, the absence of which cause the respiratory system to collapse and retreat to a closed position. Breathing with the upper part of the chest actually impedes this downward descent. Older people with respiratory disease have to use their upper chest because of relative fixation of the chest wall and loss of elasticity. It is also interesting to note the the upper part of the lungs cannot fill unless the lung root descends to create room (this does not mean elevating the chest)

I have been corresponding with Dr. Don Carlow who was the President and CEO of two large Canadian Cancer Hospitals. These were the Princess Margaret Hospital in Toronto and the BC Cancer Agency in Vancouver. He also served on the board of the Vancouver Island Health Authority. Now Dr. Carlow operates a private health care consulting company. He is a graduate in medicine from many decades ago and entered the administrative field after many years in practice. Dr. Carlow has been very interested in what my teacher, Dr. Thomas LoMonaco, had discovered in regards to the breathing and the Valsalva maneuver in singing. As singers we want to rid ourselves from using the Valsalava maneuver at all and to do this the proper breathing coordination must be employed. That means keep the inspiratory (outward expansion) going so as to resist the expiratory tension which pulls in. Here is what Dr. Don Carlow had to say about the breathing:

One of the most important facets of great singing is the concept of vowel on pitch. Very simply when someone sings they are communicating through words. Those words are made up of vowels and consonants; and since singing is involved, there is also pitch. The actual singing happens on the vowels as many consonants do not have pitch, but rather are "unvoiced". For example, the consonant sounds the letters "T", "S", "K" make have no sense of pitch. Other consonants are "voiced" in that they can have a sense of pitch. Those include "M", "N", "V", "Z" and so on. Even though these consonants are "voiced", we as singers should spend very little time on those sounds and instead should be sounding the voice on the vowels. That is how we understand the words of a song. Consonants are simply the articulation points at the start, within, or at the end of a word. The duration of a notes is spent on the vowel sound. Think of a song such as The Star Spangled Banner. The first two notes are simply on the vowel "OH". Then we have the word "SAY". This is an EH vowel sound. We do not spend time on the "S" in the beginning of the word, but rather we get right to the vowel. The following clip is a very good example of excellent vowel balance on pitch. Notice that the vowels are firmly establishing the actually pitch clearly:
Consequently, the quality of the vowels being sung is crucial. This has to do with chiaroscuro. Chiaro = clear and Scuro = dark. We can certainly understand someone's vowels even if they are overly bright and nasal. That doesn't mean we want to hear the vowels sung that way. For example, think of the character Olive Oil from Popeye. We can clearly understand her worlds and vowels, but it is not a nice sound for singing. Conversely we might also be able to understand words if someone is singing overly dark and woofy, lacking clarity, but we also do not necessarily want to hear those sounds being sung either. The ideal sounds are vowels which are dark, having full resonance, but also that are clear having what the Italians called squillante. Squillante is the overtones produced that give a "ringing" quality to a singer's voice. Those overtones are shaped by the vocal tract - mainly the position of the tongue - in order for the vowels to be clearly distinguished. You can test this out yourself by simply looking in the mirror at your tongue while you say or sing "AH", "EH", "EE", "OH" in succession. You will see that the tongue must move to form the vowel. Some of the things that can happen which distort the singing voice are that the vowel is not properly balanced, it is not centered directly in the pitch, the vowel sound fluctuates while holding the notes, and/or several vowel sounds are added which are unnecessary; e.g., diphthongs. A diphthong is when two vowel sounds are added together to form a word. For example, the word "SAY" is made up of the vowels EH and EE. S..EH...EE. In singing we have to be careful with diphthongs as they can distort the voice. Imagine singing the word SAY and instead of holding out the EH part of the word you go right to the EE part. That would be very odd sounding to an English speaker. Also, many times a singer might hold a note on a vowel and while they are holding the note the vowel does not maintain a consistent sound. Take the vowel "AH" in the word father. Imagine holding the AH and instead of it staying clearly AH we hear AH....UH....UHL....AH. Inconsistent in other words. That will make the singer sound quite unskilled and it will cause the listener to feel unsettled. As singers we should have in our minds and in our aural image that the proper vowel sound (chiaroscuro) is what sounds the pitch. Just as as piano player strikes the middle C key with their finger, the singer should be sounding the same pitch with their voice by the vowel. Listeners can easily start distinguishing great singing from mediocre singing just by this one fundamental element alone. The following clips are great examples of the vowel and pitch quality in the signing voice:
Now with the men singing you will notice as they go into their higher range there is a bit of a change in the sound. That is called covering. It is a muscular switch that happens which allows the sound to remain dark while keeping full voice all the way up to the highest notes in their range. The vowels should, however, remain clearly understood. Just as we can understand vowels spoken in a myriad of ways; i.e., nasal, bright, dark, light etc. we should still understand the vowels in the upper range even when covered. You will see that with Del Monaco you can still understand his words even in the top of his voice. One thing that is taught today is the idea of "vowel modification". This is coming at it the wrong way where the vowels are not understood in the top. Instead the "covering" switch should happen and the vowels should still be clear. This means that one must be taught how to cover properly and that is not by distorting the vowel. In classical women's voices you will notice that in the very highest notes - from about F or g 5 and above - you can no longer understand any vowels except AH or UH. That is due to the fact that the pitch is higher than the overtones needed to form a clear vowel sound. Still, women should be clearly understood in everywhere else in their range. Women who sing non classically should be understood the same way men are understood since they use a similar setup.
