Construcción de una escala perceptiva para la evaluación de la calidad de la voz cantada

In the context of vocal education, the most common pedagogical resource tends to be the verbal exchange between teacher and student. It is often difficult, however,for the participants to select the terms to be used in this discourse, as the concepts expressed are often complex and open to varying interpretations. The aim of this research is to attempt to form a consensus on some of these concepts in order to use them to build a scale to assess the quality of the lyrical singing voice. After several months of internal debate among the authors, multiple potential versions of the scale were developedandthen distributed in the form of a questionnaire to 22 experts inthe field in order to gather their input and create the most reliable possible scale. Finally, a smaller discussion was held with seven participants and key investigators. The final scale was then configuredby defining 12 parameters, with the construction of visuallyperceptual scale featuring binary oppositions of adjectives divided into 10 sections. This scale that resulted from this process is considered a valid instrument for the perceptual assessment of the lyrical singing voice.
