This article wants to highlight the fact that for an opera/operetta performer, just talent and voice are not enough, he must have a multilateral, detailed and disciplined training. Of course, the nature of the voice is the starting point of any path in subsequent evolution. To reach a high level of interpretation you have to go through certain stages of approaching an opera/operetta role. You can't start the road without knowing your vocal apparatus, its components and how to use it, for later to be able to get to the interpretation, style and personal note. A perfect opera/operetta performer will be the one who, in addition to his voice, is able to understand the subtleties of music and implicitly of the libretto, and will also have a very fair and organized technical and informational training, "The sincerity of the expressiveness of a voice that does not take into account the real personal potentials, she will be doubtful” (Cîmpeanu 1975, 28).
