The Vocal Score Profile in Verdi's Characters

OBJECTIVES: Selecting the appropriate repertoire for an opera singer may be crucial for both the prevention of voice disorders and the career progression. Here, we reviewed the score of 14 Verdi's operas to gain the data for the creation of the vocal score profile of each role. MATERIALS AND METHODS: Seven musicians were involved in the analysis process. Notes were counted and reported as absolute and relative frequency. Pitch measurements included pitch range, percentage of high-pitched notes, percentage of medium-pitched notes, percentage of low-pitched notes, high-pitched and low-pitched notes rate, percentage of the notes in the passaggio, identification of the prevalent octave, percentage of notes in the prevalent octave, and percentage of notes in a moderate range tessitura. The total phonation time was calculated for each character. RESULTS: A heterogeneity among pitch and duration measurement was found among roles within the same voice type, leading to highly different vocal efforts required by the performer. CONCLUSIONS: Data on 67 Verdi characters were gained, and the vocal demand of each role was discussed. Potentially, these results may support singers, singing teachers, and vocal coaches in the selection of the repertoire. The data may also assist clinicians in the conduction of counseling and during eventual voice therapy. Future studies must investigate the predictive value of the vocal score profile in appraising the risk of vocal injury.
