PRIMUM NON NOCERE         The first is to do no harm.         MEDICAL MAXIM

I remember Dr. Barbara Doscher at the University of Colorado describing vocal pedagogy as a negative-value proposition. Above all, don't hurt the voice. In many singers a healthy voice will emerge naturally; stay out of the way and let that sound emerge. Create a vocal warm-up, especially for younger singers, that will allow this expressive, free voice to come out.

The techniques and strategies suggested below come from observing Dr. Doscher's teaching of studio voice lessons, from reading texts on vocal pedagogy (see below for a reading list), and from three decades of teaching singers in choirs of varying ages and abilities. The primary laboratory for these exercises is the University Chorale of the University of Southern Maine, a large ensemble of mixed voices, whose membership comprises experienced singers whose principal instrument is voice, singers who are dedicated amateurs and who seek to continue their love of choral singing, and students who have been instrumentalists for most of their musical life, some of whom are singing for the first time in the University Chorale.

The suggested techniques belong to the realm of Group Voice Building (as exemplified in the work of Frauke Haasemann among others). The best-designed group vocalises in no way supercede studio voice lessons. One-on-one instruction is the best way to address the unique vocal needs of individual singers. I always ask the singers in the Chorale who study voice privately to inform me if the exercises that we do in Chorale contradict the ideas of good vocal development that they have learned in private lessons; furthermore, there is always an option for experienced singers to do their own private warm-up prior to rehearsal and to sit quietly during vocal warm-up. I ask them to inform me of their concerns, so that we may both be aware of what the other is doing.

My experience with the exercises below is that they address the dictum stated above: do no harm. The sound that I hear from this vocal procedure is clear, in tune, free, and pleasing. Singers are encouraged to sing individually with a sensitivity to the group sound.
 
 

WAKE UP THE BODY


First we must prepare the body to sing.
Several exercises can contribute to this readiness:

These exercises are several from the many effective exercises that singers can do to ready the body for singing. They generally work well in close quarters and are designed to bring a state of readiness to the body with special attention to relaxing muscles in the neck which attach to the laryngeal cartilages. Freedom and readiness are the issues: free the voice and ready the body.

OBSERVATIONS: I have used all of these exercises with varying degrees of success. The first time many years ago that I used back rubs, the students looked at me with disbelief and genial mocking, "What is this, a phys ed class?" Now if I forget to do back rubs, they ask for them.

You cannot use any vocal technique that you do not believe in. If you have confidence in the exercise and can convince the students that you are working in their interests to make them better singers, then keep at it. These exercises are not magic; they do not work overnight. Over time, however, they do work. When you notice a difference in their singing, tell them so and let them know that it is because of the exercises that we have been doing regularly. We are all working together for a better ensemble.
 
 

WAKE UP THE BREATH

The Process of Breathing: A singer's breath involves the coordination of muscles of the ribs together with muscles of the abdomen, a process called muscular antagonism. The muscles of inspiration–the external intercostals and diaphragm–work to create a partial vacuum in the lungs. Natural air pressure moves air into the lungs. The muscles of expiration–the internal intercostals and several muscular layers of the abdomen–pull the ribs down and in and the belly inward, which moves air out of the lungs across the vocal folds. (See also below: appoggio)

The Process of Phonation: The vocal folds are brought into vibration through a principle of physics called the Bernoulli Principle. (It is the same principle that gives lift to an airplane or forward motion to a sailboat.) The vocal folds are "sucked" into vibration through the partial vacuum created by the air rushing out of the lungs through the trachea. In an ideally phonated pitch,  the movement of breath is met precisely by the approximation (adduction) of the vocal folds, which are brought together with the right amount of muscular energy that is neither too tense (producing a glottal plosive) nor too relaxed (producing a breathy vocal quality). Voice and breath are precisely coordinated resulting in "singing on the breath."

Exercises: Once the body is alert and energized through a physical warm-up,
it is time to wake up the breath. These exercises are effective:

Other exercises (These exercises are from the Ehmann/Haasemann book listed below.)

The intent of these vocalises is "vocal-ease." Breath flow needs to be uninhibited and immediately connected to the sound. "To sing is to breathe."  The flow of breath may be imagined as water pouring forth freely from a garden hose. The sound on the breath is as a leaf on the stream of water, carried effortlessly and completely connected to the stream of water.
 

Observations about breathing


The Italian concept of appoggio (support) is amply illuminated by Miller (pp. 23-29). Though it is roughly translated as "support," appoggio is much more: a dynamic balance of abdominal and thoracic muscle movement, coordinated with vocal onset (phonation), which allows cooperative (antagonistic) coordination among the muscles. Its features are

WAKE UP THE NOSE

Once the body is ready and energized for singing and the breath vitalized,
it is time to "wake up the nose."

The Italian maxim goes something like this: "Put some nose in the sound without the sound being in the nose."  Virtually everyone agrees that, in the bel canto style, nasal singing is avoided. The converse is also true: "cut-off nasality" is to be avoided. Nasal sound has a twang that is generally out of place in classical singing. On the other hand, the sound of "cut-off nasality" is dull and monochromatic, flat (not in pitch but in resonance). In a balanced voice there is some nose in the sound, but the sound is not nasal. A good test is to sing and pinch the nostrils. If the sound doesn't change at all, there is no nasality in the sound: it has "cut-off" nasality. If the sound changes a lot, there is a nasal twang: it has too much nasality. If the sound changes slightly, then the balance is probably right. This is a tricky concept to teach. Studio voice teachers use a variety of techniques to get the right mix of nasality in the voice.

In a choral setting I have found that the best way to "wake up the nose" is through a humming vocalise. Ask the singers to bring the lips gently together as if humming [m]. Place the tip of the tongue easily behind the upper teeth as if singing [n]. Hum using this combination of [m] and [n].  Experiment in mid-range with random humming sounds, single pitches and gentle glissandos. Use the humming "puppy whine" in upper register as a means of developing nasal placement and as a technique to connect with head register.

Once singers are comfortable with humming, introduce this vocalise: 5-3-4-2-1 (sol-mi-fa-re-do) in major mode and in a comfortable mid-voice range. Hum the first four pitches and sustain the final pitch on the vowel [a]. Repeat several times a half step lower each time, but remaining in a comfortable range.

Another useful vocalise on the same pitch pattern (sol-mi-fa-re-do) or a more extended pattern
(sol/mi – fa/re – mi/do – re/ti – do) is [ni-ne-na-no-nu] sung while doing gentle circular gestures with your in front of the body as if lovingly stroking a cat.

Observations about Resonance

WAKE UP THE VOICE

Once you have animated the body, initiated consistent breath flow,
easily connected breath to sound, and energized the nasal placement,
it is time to extend the range of the vocalises to awaken the full range of the voice.

There are numerous vocalises that effectively achieve the goal of vocal extension. The two that I use most frequently with choirs are these:


Observations

MAKE THE SOUND BEAUTIFUL

Once you have animated the body, initiated consistent breath flow easily connected to sound, energized the nasal placement, and extended the range of the vocalises to awaken the full voice, it is time to focus on vocal beauty.
NOTICE THE ORDER: vocal beauty is the last important vocal component to be addressed.


The exercise that I use most often for beauty of sustained singing is a single pitch in mid-voice, first hummed pianissimo and then sung with gradual crescendo on a succession of vowels that grows increasingly brighter: [u - o - a]. If the vowel is truly unified, somewhere in the [a] an overtone (or sometimes two) emerges as a result of the vowel unification. When this happens, the choir is truly singing in tune.

For optimum sound, think in this order:


For optimum resonance, encourage the following:


For beautiful sound and optimum resonance, use the following:


To do all of these exercises every day will probably require 10-15 minutes, and you may not have that much time in rehearsal. I generally use a 20-25% rule of thumb for vocal warm-up and sightsinging exercises. If your rehearsal is 50 minutes, take no less than 10 minutes for vocal and musical exercises. Find a plan that works for you and stick with it. Slight variations from day to day are good, but in general keep the routine the same; in the long run that will produce the most consistent results.

Research has demonstrated the value of singing every day. The vocal exercise does not have to be complex: easy humming in the shower or simple scalar passages in the car on the way to work are effective; certainly more extensive vocalizing is needed for more rigorous singing. The benefit of humming is holistic: somehow we feel more integrated, grounded.

If students resist vocal or musical exercises, tell them that we are merely "sharpening our axes." The story is told of two woodsmen, one of whom wanted to get the jump on the other by going immediately into the woods to chop trees. The other stopped first to sharpen his axe. Woodsman #1 felled his tree first, but Woodsman #2 felled many more trees by day's end.
 

CHARACTERISTICS OF A GOOD VOICE


Much debate among singers, singing teachers, and choral conductors has centered on the topic of vibrato. I believe it is possible for good choral union and vibrato to peacefully coexist. (Consult recordings of The Robert Shaw Chorale or the Swedish Radio Choir with Eric Ericson conducting as examples.) Straight-tone singing to the point of "laser-like" vocal production (as I have heard in some choirs) is unhealthy and unpleasant. Likewise, a vocal free-for-all in which singers are allowed to do anything and everything with vibrato does not yield the most satisfactory choral sound.

A NOTE ABOUT AUDITIONS:  Choral conductors who have a great variety of singers interested in choral ensembles have the joy as well as the responsibility of choosing the singers that best match their concept of choral sound. For example, in a select chamber choir of 30-40 voices that sings primarily a cappella repertoire, I prefer the lyric soprano sound, and (if I have the choice) will seek sopranos who can sing high and soft and who can produce a sweet timbre which is still energized and musical (much like the voice of Emma Kirkby). If during the audition you can choose voices that match one another, then you can use rehearsal time to attend to musical matters rather than matter of vocal unification. The larger ensembles that sing with piano or orchestra can more easily accommodate more vibrant, ringing voices.

A NOTE ABOUT BLEND:   A chorus learns to sing together to the extent that members of the chorus have developed unified concepts of pitch, vowel, diction, rhythm, articulation, dynamics, balance, and timbre. In rehearsal I encourage all singers to


If we do these things, then I rarely find the need to say,
"Sing with straight tone."  OR  "Blend the sound."

SUGGESTIONS FOR GENERAL HEALTH


SOME PRINCIPLES OF VOCAL TRAINING

SUGGESTIONS FOR REHEARSAL

You can't sing a song in tune until you sing a phrase in tune. You can't sing a phrase in tune until you can sing a scale in tune. You can't sing a scale in tune until you can sing a pitch in tune. If you feel that the choir is singing with a generally healthy sound and intonation is still a problem, try simplifying the musical demands according to the suggested order above.
 
 

QUOTABLE

"Technique and expression must be the supporting pillars of vocal art…Technique is of no value except as it makes communication possible…Unless the emotional experiences and sentiments of a performer can be externalized, they have no value beyond personal therapeutic ones."
 Richard Miller
 Vocalism for its own sake is boring.
 Expressive singing is virtually impossible with faulty technique.


"The vocal instrument does not need to be constructed; it is available for immediate use. Lodged in a physical machine, it receives its impetus from mental and spiritual parameters of human personality. Its adaptability in channeling communication is the foundation on which human civilizations are built."

Richard Miller in RT Sataloff Vocal Health and Pedagogy p. 301

"Singers should not produce musical tones with a voice gaping wide in a distorted fashion or with an absurdly powerful bellowing, especially when singing at the divine mysteries; moreover they should avoid tones having a wide and ringing vibrato, since these tones do not maintain a true pitch and because their continuous wobble cannot form a balanced concord with other voices."

 Franchinus Gaffurius in Practica musicae (1496)

"The tremolo should be slight and pleasing; for if it is exaggerated and forced, it tires and annoys; its nature is such that, if used at all, it should always be used, since use converts it into habit…it facilitates the undertaking of passaggi; this movements…should not be undertake if it cannot be done with just rapidity, vigorously and vehemently."

 Ludovico Zacconi in Prattica di musica (1592)

Nothingness
T. Duncan

For a long time now I've been convinced that "breath-intake" was the key to free, easy and consistent singing. And I still believe in "in-and-down" and to begin singing there. But the more I sing, the more I know that on that very inspiration lies also the dangers. For when we breathe in, everything must be and remain in repose--no stiff tongue, back of throat, back of the neck muscles and chest.  Eradicate there unnecessary tensions on the intake, and you can sing.

I find too, it is best to breathe through the nose. Nose and throat tend to stiffen positions of the throat. Yes, break intake is the position--then there is no pushing, no projecting, no supporting, no grabbing of anything but the breath hookup…then the larynx and surrounding muscles work automatically on their own, not part of your volition. One is only conscious of its working…and it's a wonderful, exhilarating consciousness!

The vocal place is so small--so in front, so soft, so vocal working on its own--that any conscious help in that region destroys the natural loveliness that is there, on its own. When one is conscious of the larynx and the vocal cords while singing, one is not wholly free.

It hangs low, deep and free and has no consciousness. That is the feel of it…Nothingness.
