Abstract
No one can evaluate the singing voice in the performance of opera and artistical singing without considering the relation between the singing itself and the nature of the performance, then the evaluated voice must be useful in singing performance.
The evaluation of singing is dif icult. There is no standard of evaluation.
Vocal examination at music colleges and in competitions of professional singers employ various methods for critical evaluation. In the public singing performances, the evaluation is even more various.
Singing performance is evaluated concerning two elements : the musicality and the voice. The musicality is evaluated subjectively and variously, but the voice is evaluated objectively with the following three elements : the pitch range, the vocal loudness, and the voice quality.
Renowned singers are superior in all three elements, but especially more superior in one of these elements.
I chose several melodies having each element, from the records of renowned male singers as follows, Franco Corelli (tenor) Jussi Björling (tenor) Kurt Moll (bass) Leonard Warren (bariton) Mario Del Monaco (tenor) Boris Christoff (bass) Dietrich Fischer-Dieskau (bar-iton) .
