In the first case somewhat less, in the second somewhat more, nasal resonance would help to a greater variety of effect.
There are singers, too, who pursue the middle path with consummate art. Thus Madame Sembrich, in recent years, appears to have devoted very special study to nasal tones, whereby her voice, especially in the middle register, has gained greatly in warmth.
To fix the pupil's attention on the nasal tone and the elasticity of the palate, he should often be given exercises with French words.
SECTION VIII
SINGING TOWARD THE NOSE. HEAD VOICE
When the peak of the softest part of the palate is placed forward toward the nose, instead of being drawn up high behind the nose, as in the head voice (see plate, head voice and nasal tone), it forms a kind of nasal production which, as I have already said, cannot be studied enough, because it produces very noble tonal effects and extraordinary connections. It ought always to be employed. By it is effected the connection of tones with each other, from the front teeth back to a point under the nose; from the lower middle tones to the head tones. In truth, all the benefit of tonal connection depends upon this portion of the soft palate; that is, upon its conscious employment.
This is all that singers mean when they speak of "nasal singing"—really only singing toward the nose. The soft palate placed toward the nose offers a resonating surface for the tone.
The reason why teachers tell their pupils so little of this is that many singers are quite ignorant of what nasal singing means, and are tormented by the idea of "singing toward the nose," when by chance they hear something about it. They generally regard the voice as one complete organ acting by itself, which is once for all what it is. What can be made of it through knowledge of the functions of all the coöperating organs they know nothing of.
