The vowels and consonants are, in speaking, produced by certain noises (Geräusche), which in singing sound together with the tone. These sounds are produced by local diminutions of the cavity of the mouth, or by the opening or closing of the lips and teeth, as well as by movements of the tip of the tongue, &c., while a single pulse of the air passes through the tolerably wide open glottis and through the cavity of the mouth without regular vibrations. For the air rushes more directly out of the mouth in speaking than in singing. Of this we may be easily convinced by holding a feather before the mouth; it will show far more motion in speaking than in correct singing. If, in speaking, people would take pains to form the vowels in the front of the mouth—a habit so necessary in singing, and which is easily acquired by practice—our common speech would be much more melodious, far-sounding, and less strained. We see the truth of this when we hear words called out from a height and from a distance; the different consonants then mostly disappear, excepting the m and n, which are formed mostly in the front of the mouth. The vowels, on the other hand, are more or less plainly heard, according to the places in the mouth where they are formed. Certain it is that for the beauty of our common speech, the resonance of the cavity of the mouth peculiar to each vowel may be rendered available. A singing tone in speaking is very disagreeable. Every one who is not used to it, finds the singing dialect of Saxony in the highest degree offensive and unpleasant. Nevertheless, a more attentive observation soon teaches us that behind the noise which characterizes the several sounds in language, a timbre is heard similar to the tone in singing, and in various instances there occur regular musical intervals, as at the end of a sentence or in the special accentuation of single words. Thus, at the conclusion of an affirmative sentence the voice usually falls about a fourth from the medium pitch, and at the end of an interrogatory sentence rises about a fifth above the usual speaking tone. Words specially accented are usually a tone higher than the rest, &c. In public speaking and in dramatic representations these variations of sound are more numerous and complicated, and the inventor of the modern Recitative, Jacob Perri, even declares that he formed it by imitating in singing these variations of sound, in order to restore again the declamation of the ancient tragedians. 16
