If you find in a guitar dismantled, some piece unglued, some screw too tightly fastened, the strings not properly fixed do you expect it to sound well? do you think to play it? Are you surprised if it doesn’t sound properly? And if you have never played a violin do you find correct to judge your ear and musical capacity by playing it? Voices are like those two examples. Even when you don’t see anybody walking with his head in his hand or a leg round his neck, this doesn’t mean that his body is properly assembled to sing, or according to the second example he does naturally good and proper things to play his instrument. Some very lucky are yet properly settled and do some very right things just naturally, others not, sometimes due to simple injuries or bad habits.The worse is the judgement deaf-tone voices; I have experimented people who have submitted to, and the consequent shyness that render them more shy and uneasy in the regard of such a joyous instrument as voice is, and the consequent lack of the necessary energy and body attitude added to the problems that renders those voices out of pitch. Sometimes they also think having a bad ear and a bad musical brain. It is always possible but in my experience it had no relationship with a tone deaf voice. Tone deaf voices I have worked with, were mostly a bad shaping body, as the first example and when we properly set up they were no more tone-deaf voices, but only voices who had to learn how to sing. Some, very few in the second. To start with the ones of the first example I usually put them in a possible shape for singing (I explain that hereinafter) and I don’t ask them to match a pitch, but just to imitate me. If I put them in the condition of vibrating and I produce a good sound for them by passive attitude they will start vibrate according to one of the overtones in my sound, if possible to their body the easiest one, the correct pitch I wanted, if yet impossible something normally not that far in very little time. To make it possible there are many simple and less simple exercises to give the minimal elasticity and shape of a possible correct sound. I have to play them for the first period as the second range strings of a viola d’amore. The Viola d’amore was an ancient viola with a double range of strings, one under the other. The player played the upper range and the other vibrated according to the superior “per simpatia” was said, by sympathy. What is nice in that passive way is that the lack of tension to match a pitch will live the body smooth enough to simply let itself being changed and shaped by the teacher and vibrate. In that way they have the experience in the body of a sound less incorrect, a feeling to remember, a feeling to relate to look for sounds and pitches, a feeling and an experience that will feed body and brain and give a quiet and easy sense of comfort while producing sounds. The body and the brain will remember those feelings and will reproduce the same patterns while you will play less and less for what is acquired and as before to obtain more difficult and complex things. The teacher has the necessity to understand well the inside shaping of the student. What renders so difficult to understand what and how is badly set up is the fact that we don’t see the elements of our instrument, they are for the most part inside and very rarely we can feel it before having made a work on them, so how can a teacher know what to do? And how to do if the person doesn’t even feel the existence of he has to move and change? A good teacher and a good singer should be able to feel in himself what is happening in the student, but I think that on that subject the teaching world should think about developing proper methodic to deal with, and that’s why I talk about voice luthiery, a field to explore and develop. I can usually feel how they are shaping themselves, because I let my body being guided by their shape and opening the same communicative channel of musicians I can make them take the shape I am assuming. This shape I assume and want them to imitate must be not that far from the shape they have and at the same time they must have the elasticity to assume it. I mean that I have to assume me their shape and then to ameliorate it in a suitable way. To give them the elasticity I make them do some simple and less simple physical exercises. To maintain that elasticity and not make an intellectual control that will use movement pattern yet existing and not useful I ask them to lay together as children: I do they do, I do they imitate without thinking or analyzing my voice or sound or movement. When we think I experienced that some part of the body will get stiff and than it will be impossible to sing correctly without being yet nearly a singer. We can think before and after, not during.The exercises I give to the student will give the correct shape and strength or the necessary soft to all the body’s parties, and work on the coordination of the single parts. Singing is a complexe activity and we just have to render the brain and body in the possibility to execute that complex coordination.
