The tone must be idealized with reference to place and form. The student
should imagine the tone outside that resonant chamber of the nares most
distant from the vocal cords. This will bring the consciousness outside
that part of the nose which is between the eyes. The anterior portion of
the nares is, so far as place and consequent resonance are concerned,
the dominant center of the voice. My reason for calling this the
dominant center of the voice is that when the tone is perfectly directed
toward this chamber, all the resonant passages open freely through the
entire nares, mouth, and pharynx to the vocal cords; and also the tongue
has a tendency to relax its rigidity.
