Many vocal teachers advise their pupils not to sing in choirs and choruses. There may be some ground for the belief that students are apt to fall into bad vocal habits while singing in the chorus. But this risk is entirely avoided by the teacher having his pupils sing in his own chorus, under his own direction.
Another important feature of the musical education is the hearing of good music artistically performed. Vocal students should be urged to attend the opera and the orchestral concerts. They should become familiar with the different forms of composition by actually hearing the masterpieces of music. Chamber music concerts, song recitals, and oratoric performances,—all are of great advantage to the earnest student. When students attend the opera, or hear the great singers in concerts and recitals, they should listen to the singers' tones, and not wonder how the tones are produced.
Ear Training
No special exercises can be given for the training of the ear. The sense of hearing is developed only by attentive listening. Every vocal student should be urged, and frequently reminded, to form the habit of listening attentively to the tones of all voices and instruments. A highly trained sense of hearing is one of the musician's most valuable gifts. A naturally keen musical ear is of course presupposed in the case of any one desiring to study music. This natural gift must be developed by exercise in the ear's proper function,—listening to sounds.
Experience in listening to voices is made doubly effective in the training of the ear when the student's attention is called to the salient characteristics of the tones heard. In this regard the two points most important for the student to notice are the intonation and the tone quality.
Absolute correctness of intonation, whether in the voice or in an instrument, can be appreciated only by the possessor of a highly cultivated sense of hearing. Many tones are accepted as being in tune which are heard by a very keen ear to be slightly off the pitch, or untrue to the pitch. This matter of a tone being untrue to the pitch is of great importance to the student of music. Many instruments, when unskilfully played, give out tones of this character. The tones are impure; instead of containing only one pitch, each note shades off into pitches a trifle higher, or lower, or both. This faulty type of tone is illustrated by a piano slightly out of tune. On a single note of this piano one string may have remained in perfect tune, the second may have flatted by the merest fraction of a semitone, and the third by a slightly greater interval. When this note is played it is in one sense not out of tune. Yet its pitch is untrue, and it shades off into a slightly flat note. In the case of many instruments, notably the flute, the clarinet, and the French horn, unskilled performers often play notes of this character. But in these instruments the composite character of the note is vastly more complex than in the piano. A very keen ear is required to appreciate fully the nature of this untrueness to the pitch. But this is exactly the kind of ear the singer must possess, and it can be acquired only by the experience of attentive listening.
The voice is especially liable to produce tones untrue to the pitch. Stiff-throated singers almost invariably exhibit this faulty tendency. An excessive tension of the throat hampers the vocal cords in their adjustments, and the result is an impure tone. This is more often the cause of an artist singing out of tune than a deficiency of the sense of hearing. Many singers "sharp" or "flat" habitually, and are unable to overcome the habit, even though well aware of it. Only a voice entirely free from stiffness can produce tones of absolute correctness and perfect intonation. Du Maurier hit upon a very apt description of pure intonation when he said that Trilby always sang "right into the middle of the note." As an impurity of intonation is almost always an indication of throat tension, vocal teachers should be keenly sensitive to this type of faulty tone.
Tone quality is a subject of surpassing interest to the musician. Whatever may be thought the true purpose of music, there can be no question as to one demand made on each individual instrument,—it must produce tones of sensuous beauty. A composer may delight in dissonances; but no instrument of the orchestra may produce harsh or discordant tones. Of beauty of tone the ear is the sole judge; naturally so, for the only appeal of the individual tone is to the ear. Melody, rhythm, and harmony may appeal to the intellect, but the quality of each component tone is judged only by the ear.
Each instrument has its own characteristic tone quality. The student of singing should become familiar with the sounds of the different orchestral instruments. Attention to this is extremely valuable in the training of the ear.
Beauty of tone was seen to be the truest and best indication of the correct vocal action. The voice has its own tonal beauty, entirely different in character from any artificial instrument. Students of singing should listen for every fine shade of tone quality in the voices of other singers. They should learn to detect the slightest blemish on the quality of every tone, the slightest deviation from the correct pitch.
