It is very interesting to note how much a word can gain or lose in fulness and beauty of tone. Without the use of auxiliary vowels no connection of the resonance in words can be effected; there is then no beautiful tone in singing, only a kind of hacking. Since it must be quite imperceptible, the use of auxiliary vowels must be very artistically managed, and is best practised in the beginning very slowly on single tones and words, then proceeding with great care to two tones, two syllables, and so on. In this way the pupil learns to hear. But he must learn to hear very slowly and for a long time, until there is no failure of vibration in the tone and word, and it is all so impressed upon his memory that it can never be lost. The auxiliary vowels must always be present, but the listener should be able to hear, from the assistance of the oo, only the warmth and nobility of the tone, from the a and e only the carrying power and brilliancy of it.
SECTION XXX
RESONANT CONSONANTS
K, l, m, n, p, s, and r at the end of a word or syllable must be made resonant by joining to the end of the word or syllable a rather audible ĕ (eh); for instance, Wandele, Gretele, etc.
A thing that no one teaches any longer, or knows or is able to do, a thing that only Betz and I knew, and with me will probably disappear entirely, is the dividing and ending of syllables that must be effected under certain conditions. It may have originated with the Italian school.
I was taught it especially upon double consonants. When two come together, they must be divided; the first, as in Him-mel, being sounded dull, and without resonance, the syllable and tone being kept as nasal as possible, the lips closed, and a pause being made between the two syllables; not till then is the second syllable pronounced, with a new formation of the second consonant.
And this is done, not only in case of a doubling of one consonant, but whenever two consonants come together to close the syllable; for instance, win-ter, dring-en, kling-en, bind-en; in these the nasal sound plays a specially important part.
