Bottom-End, Writings and Reviews from Music Producer Pete Strobl

One of the first questions I ask a voice student is, “What is the first thing you do in order to sing a note?” The answers range from, “Breathe from my diaphragm” to “Stand up straight” and open my mouth.” But I think that I’ve heard the right answer only once. The first thing a singer must do is to hear the note. Remember my second rule…you can find it in the sidebar. “It is always simpler than it seems.”

This is not exclusive to singers. This first thing you do pertains to any and every musician. Before you make a sound, you have to hear the sound you are about to create. This is a mental tool that is valuable in conceptualizing that which you are attempting to create. But the importance of hearing brings me to my subject.

Have you ever performed or attended a concert and experienced ringing ears afterwards? You leave the venue, get on a plane or go to your room and the ringing is more than annoying. You feel as if it will never stop. So you turn off the TV, shut off the iPod, anything to hear only silence. But the quieter it is, the more pronounced the ringing becomes. It is time to heal your hearing.

First, here is the fast lane explanation of how your ear works. Sound waves enter the ear canal, striking the ear drum, setting into vibration the attached stirrup which passes the vibrations along to a bone-like structure called the anvil after which the vibrations are processed by thousands of little hairs, each attached to a nerve which tells the brain what to think of it all. When the sound pressure is too high, those little hairs call it quits and your brain gets less information. So what do you do? You turn it up, of course. Causing more of the little hairs to take a powder, so you…turn it up!

Now, those little hairs are frequency specific and if the sound pressure level stays elevated long enough, they will lay down and stay down…forever. That’s why drummers often lose hearing in the high frequency range. Good god, hitting a snare drum all night long is worse than passing out targets at the firing range.

Alright, that’s the problem, now what is the cure? Don’t ask me, I’m no doctor. I guess that the ultimate solution would be to stop making all that racket and stop going places where they are making a racket. But you gotta work. You know how to rock and roll. Here is something that might help you to rock and hear.

Let’s get a little anthropomorphic here and think of all those little hairs as tsunami survivors. Once the racket stops, they are all clinging to each other in fear of the next wave. After the initial look around for survivors, they start to talk to each other. “Did you hear that shit?” “Yeah man, it was LOUD!” “Boy, it sure is quiet now.’ ” Yeah, I wonder what’s next.” Did you hear anything?” “No, you?” “Anybody seen Bob?” “He’s down for the count.” and so on. Now, these little guys are tiny and they have little tiny voices. But when enough of them start calling out to each other, we hear it as a ringing in the ears.

Having taught in the classroom, I can tell you that the best way to get the attention of a noisy class is to speak quietly. Standing in silence just makes you a target for paper airplanes. But a whisper will always get the attention of a crowd. So here is how I get the little guys in my inner ear to shut up and go back to work.

Put on a pair of good quality headphones. Now play a string quartet or maybe the Bach Unaccompanied Cello Sonatas. And turn the volume down to the point where you have to struggle to hear the music. Very low. Inside your ear, the little hairs’ conversation starts to dwindle and finally die down. When the music hits the inner ear, you can imagine them saying to each other, “Did you hear something?” “Shh! What was that?” “I think it’s a violin.” Shut up man, It sounds nice.” “Hey, let go of me, I can stand up on my own.” “Will you guys shut up already, I want to hear this.”

And soon, the little hairs stop talking and are back up and dancing. When you make them seek out something to do, something to hear, they work very efficiently. The ringing will go away, and you can finally get some much needed rest. Try it. A little classical music never hurt anybody and your ears will be full of happy little hairs for years to come.

Heal your hearing.

First things first. Before jumping into a series of vocal exercises that could easily harm more than help a singer experiencing fatigue, it is important to root out the cause of the problem. Again, keep in mind that every singer is different, with a unique instrument, and with a unique set of demands to be made on that instrument. Applying the generalized principles of “correct” vocal production can result in more problems than solutions.

Rather than write a boring litany of all the possible cause and effect formulae, let me illustrate by creating a hypothetical scenario. Sven the Viking is the lead singer of a metal band specializing in “Nordic Pillage Rock.” Sven’s band is preparing for a six month world tour and although he is gifted with massive physical presence, the stentorian tone which is his trademark is losing torque with every rehearsal. He wants two things. 1. The strength to sing a show without losing his voice, and 2. the prospect of beginning every show from square one rather then with vocal fatigue held over from the previous show.

Lets summarize what is before us:

Sven is a screamer…If we change that, his fans will pelt him with bottles.
Sven smokes…good luck changing that one, Sven just got out of drug/booze rehab and is clinging to his last known vice.
Sven is a hard worker and has reached his level of success by storming through whatever obstacles were in his path.
Sven has reached the point of saying, “It can’t get any worse, I’ll try anything.” He is receptive to my suggestions and “believes” that what I say will help him.

We start by listening, and watching Sven sing a song. Sven has no problem with support. But as I look at his upper chest and neck, I can see the muscles working overtime. Sven is trying to squeeze 10 pounds of sound through a 5 pound opening. He sings with his chin up and opens his mouth wide by raising his head. All wrong! But the sound and delivery are exactly the same as on Sven’s records.

Simply put, we need to find the range where Sven’s voice is most relaxed. I start by having Sven lay on his back. Now his head is in the proper posture for singing. (For a full explanation of this, see my entry Vocal Architecture.)

I have Sven hoot like an owl, very lightly and in his falsetto, or head voice. I find that there are 5 or 6 notes that he can “hoot” so we exercise just those notes, first by singing “Hoooo” in a light breathy tone as if blowing across a bottle. Remember, the idea is not to make a great sound, but to get the vocal machinery operating in its most relaxed state. I’m looking for free and easy vibration without the tension present when Sven does his act.

Next, I use the syllable “Voo” and exercise the same notes. I start with the “Hoo” in order to begin the tone with air. This allows the vocal cords to engage in a non-violent way with a minimum of tension applied by the surrounding muscles. (See my essay on this principle here) Using the “Voo” brings the initiation of the tone, forward as the lips form the “Vee” consonant, also allowing the tone to ride on a column of air. Repetition of these relaxed exercises will manipulate the mechanism and allow the vocal cords to vibrate freely thereby providing much needed therapy much as an athlete would have sore muscles worked on by a physiotherapist.

After the upper register feels free, I look for the most relaxed range of the lower voice. This is usually in the normal speaking range. The same principles apply, find the easiest notes and exercise them by beginning the tone on a column of air. The “oo” vowel is very helpful because when produced properly, it is not a loud vowel. I ask Sven to sing “Hoo” and “Voo” as if he were imitating very low level feedback.

Depending on the individual, various other vowel sounds are brought into the exercise regimen. Normally, “oo” and “oh” feel the most relaxed while the open “ah” will tend to expose problem areas. I will move through the vowels from “oo” to “ah” with an effort to letting the “ah” vowel be influenced by the habits of free vibration being learned from the “oo.”

This would be the very beginning. If Sven were not able to see me every day, I would record a regimen of exercises as he sings them and hope that he repeats these at least once a day. Progress is absolutely inevitable, IF the work is done. When Sven goes on tour, he will find that he is still screaming his guts out, his fans are loving it, and by sticking to a regimen of daily vocalization, his vocal mechanism will be able to survive.

Of course this scenario doesn’t represent the way it’s supposed to be according to every teacher I’ve learned from over the years. But what does Sven care about “Bel Canto” technique? Sven lives in the real world and only a real world approach will get him to the end of the tour.

So…to continue a discussion of vocal fatigue. There is a good possibility that I may go off on a bit of a rant but I’ll try to stay on point long enough to give some advice on conquering fatigue and rehabilitating the vocal mechanism. I find it important, however, to take a quick left turn and provide some background for my method.

I spend a lot of time in my lessons discussing what I call “vocal mechanics.” The human voice is produced by a machine made up of levers, tubes, reservoirs, intake manifolds, exhaust systems, tone generators, resonators, springs…Jesus, it sounds complicated, doesn’t it? The truth is, yes, it is extremely complicated. The good news is that most of these systems operate involuntarily and with utmost efficiency with every beat of your heart.

Singing can be a very simple process, and I try to keep technique as simple it can be. But vocal fatigue is a symptom of one or more of the many components of the mechanism being operated in a manner that causes other components to be overworked. At that point it becomes important to carefully analyze the singer’s technique with a mechanic’s eye toward detail and efficiency of operation.

Most singers suffering from fatigue experience discomfort or pain in the throat, hoarseness and inflexibility in the upper register. This indicates that the vocal cords are being misused. Now, try to move your vocal cords. Go ahead, move just the left one, now move the right one. Can’t do it, can you? So how can you expect to correct the abuse of the vocal cords without ascertaining precisely which component of the mechanism is not doing its job and causing the vocal cords to work overtime?

The vocal cords, or “vocal folds” as they are sometimes called, can more precisely be described as a valve. This valve’s primary function is to act as the last line of defense in protecting the breathing mechanism from foreign objects. When you swallow, the epiglottis closes over the airway to cap the opening. Below this cap, the vocal cords close across the airway just in case anything gets past the epiglottis. The vocal cords, or “valve” is closed when swallowing. Hum. Now try to swallow while humming. Impossible.

The function of the vocal cords as the “tone generator” of the vocal mechanism is secondary to survival, but primary for communication. It’s the architecture of the human mouth with it’s ability to form words that separates humans from the non-speaking species. The process by which tone is produced by the vocal cords is discussed in detail in my post from May, 2006 entitled, “Bernoulli, Doppler and Natural Vibrato’” found in the archives.

To illustrate how the abuse of the cords results in fatigue, hold your hands in a praying position with palms flat and together. Pull your hands three inches apart and put them together again twice per second lightly, so they just touch. Repeat this for the length of a short song…say, two minutes. This is a simulation of the action of the vocal cords when singing. Now repeat the process, only this time clap your hands firmly together, again, twice per second. Do this for two minutes. How do your hands feel? They hurt, don’t they? If you put your palm against your face, you’ll feel how hot they have become. This is precisely what happens to the vocal cords when you scream, yell or sing with crap technique. And as small and delicate as the vocal cords are, it’s no surprise at all that an ounce of abuse can require a pound of rehabilitation.

If you slap your hands together for an extended period, callouses will form at the points of most violent contact. When these irregularities form on the leading edge of the vocal cords, the surface of the cords are not able to come to a complete closure and some air flows through the opening(glottis). The resultant tone is breathy or hoarse, and there is a build up of heat and pain from slapping the cords together. Voila…Vocal Fatigue.

Okay, so I took a wide left, but let me get back on the road and suggest the first step in alleviating vocal fatigue. Step one? Stop talking! Don’t say another word. When you speak with a worn out voice, you just aggravate the cords. Step two, if you can afford to, don’t sing. It hurts and you sound like shit anyway, so just stop it. You’re doing something wrong and until you discover what that is, you’ll just continue to cause damage. Usually the fault lies in two areas. These are Breathing and Support, and Vocal Architecture, also covered in the archives. Step three, deep breathing exercises. There is no short cut. It all starts with breathing and it doesn’t have to be complicated.

In a future post, I will go into more detail as to the exercises that may be helpful in rehabilitating abused vocal cords. In the meantime, If you suffer from vocal fatigue, SHUT UP, DON’T SING, and BREATH DEEP.

Vocal fatigue can affect every singer to varying degrees. In the amateur ranks, the cure is usually painless and very simple. If one is not under the pressure of having to sing in order to keep a chicken in the stew pot, that singer can just stop for a while and rest will allow the fatigue to subside. Even in cases where the fatigue was brought about by bad singing technique, rest usually does the trick. After a short break, the singer can go back to the karaoke bar or the church choir and resume singing, bad technique intact, until fatigue once again dictates a period of inactivity.

But what about the professional singer who has dates on the calendar? There are professional singers who may have less than perfect technique and suffer from vocal fatigue. Indeed, there are a great many professionals whose lack of extensive vocal training can be an integral element of their style. Introducing too much correct technique into the style of a known artist with a characteristic sound can be catastrophic. I know that I’ll get heat for that last statement, but only from the academic crowd. But screw you, you know who you are…snobs! Get back in your classroom and shut the door.

I have worked with quite a few pros who suffer from vocal fatigue. The first step in helping such a singer is to provide reassurance. The stress of thinking that one has lost one’s voice can be the biggest hurdle to overcome when rehabilitation is required. After a singer buys into the possibility that the voice can and will come back, the real work can begin.

A singer should never think about technique when performing. If proper care is taken to develop exercises which gently heal the overused elements of the vocal mechanism, it will be able to recover sufficiently for the singer to continue performing without changing style or character. When a singer’s style includes tension or a tight throat, there is damage done to the mechanism every performance. Consequently, every night’s work begins a bit worse off than the last, until fatigue doesn’t allow the singer to continue. Certain exercises designed specifically with each particular singer in mind can serve to get back what is lost during performance much like a football player might use water jet treatment or massage to therapeutically loosen fatigued or damaged muscles. This requires patience, trust, thorough knowledge of vocal mechanics and imagination. The sort of thinking that can deal with vocal fatigue in a well-known singer is the sort of creative thinking that may sometimes be frowned upon in academia. But professional singers live and work in the real world and sometimes an academic approach can fall short of success in real world scenarios.

My favorite tube amp technician is a purist. ( Yeah, I know. This is going off on a tangent but stick with me.) You can’t pay him enough money to do a modification on a vintage amp. But there is one area where he will fudge the specifications. Say you have a sweet Fender Tweed Deluxe. The thing has been running with the same old capacitors for 30 years and is starting to make rice crispy noises as it warms up. Now, normally, an amp tech would replace the old, tired and leaking capacitors with new ones made to the original manufacturer’s specifications. You plug in to the amp and, gosh, doesn’t it sound fresh and clean. But wait. What happened to that lovely warmth, that flannel-like fuzzy mantle that surrounded your guitar sound? Aha! This is a case of correctness spoiling character. My guy will tell you that your amp does need capacitors and if you don’t replace them, the sound will deteriorate further over time. But the deterioration up to this point has resulted in a sound that you like. So he will measure the value of the capacitors as they are today, and install new ones at the deteriorated value. Now your amp will have that character that you’ve grown to love without deteriorating. No, the values of the new capacitors are not correct according to the factory schematic. BUT WHO CARES!! The amp performs the way you like it to and it will do so dependably.

Now, I don’t know if you’ll understand the correlation between my amp rap and the issue of alleviating vocal fatigue. Suffice it to say that creativity is not limited to performers. The creative minds that work in support of creative performers can have a great impact on what you see and hear on the concert stage.

Think “outside.” Think of something you do as a result of habit, and just for today, do that one thing differently…but don’t hurt yourself!

Next entry, I’ll discuss some pertinent vocal exercises and how they came about.

As I have discussed in previous posts, breath control and support are essential to singing. Here is a vocal exercise that has proven to be extremely helpful in building better support. Keep in mind that the exercise is only designed to increase the body’s awareness of proper support. It is not a “tone” or “range” exercise.

1. This exercise uses a 5 note descending scale, 5-4-3-2-1.
2. This exercise should be sung only in same range as the speaking voice. You should sing no higher than is comfortable.
3, Sing each pitch on the vowel ‘Oh’, starting the sound with an ‘H’ or a slight burst of air. This requires a quick contraction of the abdominal muscles. Ho-Ho-Ho-Ho-Ho. The sequence is sung with one breath.
4. Each note should be short and have impact. It should feel the same as if you are laughing…belly laughing.
5. Using a very narrow range, go up and down by half-steps. The entire range of the series should not exceed one octave.

Repetition is the name of the game here. Don’t let yourself get bored. Feel each note as being important. really work the abs and put a good ‘H’ on each note. The point is to use a lot of air…more that you would need for a typical song phrase. Repetition of the sequence will train the body to take in the right amount of air per phrase.

After 5 to 7 minutes, double up the Ho’s per note. in other words:
HO-HO, HO-HO, HO-HO, HO-HO, HO

As before, make every note important. Sing very staccato in short, detached bursts.

This exercise is the base coat of what should be a 20 minute daily workout. Gradually, the benefits will seep into your singing and you will realize an improvement in pitch and density of tone. And remember, the place to think is in the practice room. efficient exercises will enable you to interpret songs without thinking of technique. Don’t make it difficult…it’s always simpler than it seems!

Some of my recent lessons have inspired me to write about a subject that is extremely important to good vocal production. I call it Vocal Architecture. Good posture is a must if one is to breathe properly for singing. But Vocal Architecture has more to do with the efficient use of body structures and how they interact.

The main area of concern is usually the neck and head. The weight of the skull sits precariously at the top of the spine and is continuously balanced by various muscles. A reasonable parallel would be the Segway Human Transporter which has an onboard computer that calculates and adjusts changes in balance at the microsecond level. An improper tilt can cause a great deal of unnecessary tension which will cause vocal fatigue and can also completely change the sound of the voice. Many questions can best be answered by looking back into primitive human history. The question here is, what is the proper position of the head and why?

I find that many singers hold their head a bit too high which causes multiple problems. The weight of the back of the skull compresses the neck muscles, the throat muscles are stretched unnaturally, causing tension in an extremely vulnerable area, and the entire balance of the body is put into a precarious attitude. Head tilt seems like a small detail, but once a singer achieves the proper balance, everything changes for the better… immediately.

I teach singers to “Lead with their forehead and look intently to the horizon.” I also teach the importance of dropping the jaw to open the mouth wider as opposed to raising the head. Here are a few reasons why this is so important:
1. This position allows the skull to be balanced equally by all the muscles around the neck.
2. Focusing on “leading with the forehead” is a mental image that tends to help the singer picture the sound as emanating from the resonant chambers of the mask.
3. Dropping the jaw eliminates tension in the area surrounding the larynx which must be absolutely free of undue tension in order for the voice to be produced correctly.

Dropping the jaw also has a massive affect on what happens inside the mouth and throat. The very tip of the soft palate or, the roof of the mouth, is called the uvula. When the jaw is lowered, this little guy points downward creating a wider passage for sound waves to pass up into the sinus area. This could be compared to turning up the high frequency tweeters in a stereo system. The difference in the sound of an AH vowel when the jaw is dropped just a small amount is amazing.

As to posture, I prefer that a singer do vocal exercises standing with feet shoulder width apart and one slightly in front of the other. There are certain exercises that include slight crescendos or extensions of energy and I like to see a singer shift weight forward on the crescendo and back on the diminuendo. Merely shifting weight from one foot to the other will expend energy in the legs and usually results in better support from the torso.

I think of singing as a very physical process and these slight variations in balance will have good results without clogging the mental process. The physical aspects of singing, when drilled and practiced extensively, should become second nature. Good habits will allow more “CPU” usage to be alloted to the interpretation of a song.

So…getting back to the dawn of human history, I imagine primitive man as a hunter-gatherer who had to have finely tuned scanning skills in order to provide himself with food and to anticipate both the danger of predatory animals and the presence of food animals in the distance. Primitive man walked erect, thereby making use of his built-in periscope. To anticipate what was in store for him, he looked to the horizon…out and down. His horizon was much different than ours. When we look for what we need, we look at shop windows and billboards…we look up. Our scanning and awareness has deteriorated to the point that any distraction can cause us to trip or step off of a curb.

My take on Vocal Architecture may seem a bit quirky, but it works. Become primitive man and look down and out to the horizon. Sing with a purpose, as if survival were hanging in the balance.
