Comment: From folk to opera. This singer now has a choice.
Quote: The stature of a singer is measured in technical terms by his ability to command AT WILL a wide variety of tonal coloration. This is made possible by associating his expressive aims with their physical counterparts as reflected in the texture of the registration, the resonance adjustment, and the vowel quality. These are his interpretive tools and cause the technique to be securely based upon functional freedom. (The Free Voice)
