Training the voice is a complex work of opposite forces, and it does not work with the simple opposition of opposite muscles. We can think in a more complete and refined way putting the opposition on the functions so to work in some parts or in all the muscular chains and obtain not by luck all the different possibilities of voices and not strain or remain with a too limited voice.
If you are a boxeur or a sprinter will you train just in a relaxed and smooth way, as for example doing only Tai Chi? Relaxation can be useful and even fantastic as Tai Chi, but it is one of the tools possible and useful in voice training and it does not serve all the required purposes for professionals and performances or certain styles. Music and repertoire are made of different rhythms and accents and strenghts and if we do not train the system voice in a rational and precise way to be the perfect image of the music we are going to perform we will have a problem. Of course how to do that and from where and by what passages develop strengths and speeds requires great care and wisdom as in every training, but the answer always smooth and legato and relaxed is not the answer correct.
My first two talks on some fundamental questions of vocale technique, often not so clear in students and singers and not clearly explained through their effects and consequencies so that they remain scary and refused in the first step. Often they are related as the fact that when you cover the sounds you will have in your sound not the effect of copertura but the disclosure of the state of your sustain and appoggio. I mean that not covered sounds have a different kind of pressure from the effective and true sustain (a true sustain always have a copertura effect), so you cover and the vocal folds do not respond anymore to the excess of pressure not correct. You will immediately hear how much the correct and true sustain is developed and the really good news is that with copertura it is safe and not tricky to develop the effective and true sustain. So if you refuse covering you will probably never develop a real and effective sustain, and this just because you were scared by the sound after copertura that was just the first step of the process and not the arriving point of the process. Many things in vocal technique present this two step process, I will try to clarify some of those for you on Istagram in my IGTV.
And the first is on copertura. 🙂
