The result of this, as regards sound, is the so-called nasal voice, which is very much like caterwauling, and I need not say that there is no fascination in it--on the contrary its tendency is to destroy any other kind of attraction.

It is generally far more due to an ill-trained, unregulated, excitable, nervous temperament than to any other cause.
The training the voice to a subdued state "like music in its softest key," or to rich, deep tones, though it be done artificially, has an extraordinary effect on the character and on others.

It is associated with a well-trained mind and one gifted with self-control.

One of the richest voices to which I ever listened was that of the poet TENNYSON.
I can remember another man of marvelous mind, vast learning, and aesthetic-poetic power who also had one of those voices which exercised great influence on all who heard it.
There is an amusing parallel as regards nasal-screaming voices in the fact that a donkey cannot bray unless he at the same time lifts his tail--but if the tail be _tied down_, the beast must be silent.

So the man or woman, whose voice like that of the erl-king's is "ghostly shrill as the wind in the porch of a ruined church," always raise their tones with their temper, but if we keep the former down by training, the latter cannot rise.
I once asked a very talented lady teacher of Elocution in Philadelphia if she regarded shrill voices as incurable.
