THE SENSATIONS OF THE PALATE
The sensations of the palate are best made clear to us by raising the softest part behind the nose. This part is situated very far back. Try touching it carefully with the finger. This little part is of immeasurable importance to the singer. By raising it the entire resonance of the head cavities is brought into play—consequently the head tones are produced. When it is raised, the pillars of the fauces are lowered. In its normal position it allows the pillars to be distended and to close the head cavities off from the throat, in order to produce the chest tones; that is, to permit the breath to make fullest use of the palatal resonance. As soon as the soft palate is lowered under the nose, it makes a point of resonance for the middle range of voice, by permitting the overtones to resound at the same time in the nose. (See plate, middle range.)
Thus the palate performs the whole work so far as concerns the different resonances, which can be united and separated by it, but must always work together in close relation, always bound together in all tones, in all kinds of voices.
The lowest chest tones of the bass, the highest head tones of the soprano, are thus the two poles between which the entire gamut of all voices can be formed. From this it can be perceived that with a certain degree of skill and willingness to work, every voice will be capable of great extension.
