"I am asked sometimes if I teach registers of the voice. I can say
decidedly no, I do not teach registers. The voice should be one and
entire, from top to bottom, and should be produced as such, no matter in
what part of the voice you sing. Throughout the voice the same
instrument is doing the work. So, too, with voices of different caliber,
the coloratura, lyric and dramatic. Each and all of these may feel the
dramatic spirit of the part, but the lighter quality of the voice may
prevent the coloratura from expressing it. The world recognizes the
dramatic singer in the size of the voice and of the person. From an
artistic point of view, however, there are two ways of looking at the
question, since the lyric voice may have vivid dramatic instincts, and
may be able to bring them out with equal or even greater intensity than
the purely dramatic organ.
