Duval asserts: "Long, sustained tones are too difficult for the young voice. One should sing medium fast scales at first."
LENGTH OF TIME FOR DAILY PRACTICE
It may be helpful to know about how much time the artists devote to daily study, especially to technical practice. It is understood all great singers work on vocalizes and technical material daily.
Caruso is a constant worker. Two or three hours in the forenoon, and several more later in the day, whenever possible. Farrar devotes between one and two hours daily to vocalizes, scales and tone study, Lehmann counsels one hour daily on technic. Galli-Curci gives a half hour or so to vocalizes and scales every morning. Martinelli practices exercises and vocalizes one hour each morning; then another hour on repertoire. In the afternoon an hour more—three hours daily. Easton says: "It seems to me a young singer should not practice more than an hour a day, at most, beginning with two periods of fifteen or twenty minutes each." Anna Case says: "I never practice when I am tired, for then it does more harm than good. One must be in good condition to make good tones. I can study and not sing at all, for the work is all mental anyway." Muzio states she gives practically her whole day to study, dividing it into short periods, with rest between.
Frieda Hempel says: "I do about two hours or more, though not all of this for technic. I approve of a good deal of technical study, taken in small doses of ten to fifteen minutes at a time. Technic is a means to an end, more in the art of song than in almost any other form of art. Technic is the background of expressive singing."
Sophie Braslau is an incessant worker,—"at least six hours a day. Of these I actually sing three hours. The first hour to memory work on repertoire. The second hour to vocalizes. The rest of the time is given to repertoire and the things that belong to it." Barrientos states she gives about three-quarters of an hour to vocal technic—scales and exercises—each day. Duval advises the young student to practice two half hours daily, two hours after eating, and rest the voice one day each week, during which she studies other subjects connected with her art. Oscar Saenger says: "One should practice in fifteen-minute periods, and rest at least ten minutes between. Sing only two hours a day, one in the morning and one in afternoon."
WHAT VOWELS TO USE
There seems a divergence of opinion as to what vowels are most beneficial in technical practice and study. Galli-Curci says: "In my own study I use them all, though some are more valuable than others. The Ah is the most difficult of all. The O is good; E needs great care. I have found the best way is to use mixed vowels, one melting into the other. The tone can be started with each vowel in turn, then mingled with the rest of the vowels." Mme. d'Alvarez often starts the tone with Ah, which melts into O and later changes to U, as the tone dies away. Bispham has the student use various vowel syllables, as: Lah, Mah, May, and Mi. With Oscar Saenger the pupil in early stages at least, uses Ah for vocalizes. Duval requires students to use the vowel Ah, for exercises and scales, finding the others are not needed, especially excluding E and U as injurious. Griffith uses each vowel in turn, preceded by all the consonants of the alphabet, one after another.
HALF OR FULL VOICE?
Shall the young singer practice with half or full voice seems a matter depending on one's individual attainments. De Luca uses full power during practice, while Raisa sings softly, or with medium, tone, during study hours, except occasionally when she wishes to try out certain effects. Martinelli states he always practices with full voice, as with half voice he would not derive the needed benefit. Mme. Easton admits she does not, as a rule, use full voice when at work; but adds, this admission might prove injurious to the young singer, for half voice might result in faulty tone production. Anna Case says when at work on a song in her music room, she sings it with the same power as she would before an audience. She has not two ways of doing it, one for a small room and another for a large one. Mr. Duval advises the young pupil to sing tones as loudly and deeply as possible. Singing pianissimo is another fallacy for a young voice. This is one of the most difficult accomplishments, and should be reserved for a later period. Oscar Saenger: "The tone should be free, round and full, but not loud."
