In choral singing there is the tendency to lean on certain singers who are natural leaders, with the result that there is little independent listening and individual culture, even if the singer could hear his own voice well, which is not usually the case. The same objections and others apply to class singing in schools, which does little for music, and tends to make slovenly singers. If some of the time given to school singing were taken up in illustrating why certain musical selections are good, and others mere rubbish--in other words, in forming the taste of the nation in the children--a valuable work would be done; but school class singing, as commonly carried out, tends rather to injure than develop voices and good musical taste. We cannot honestly pass by the subject of Wagner's music and some of its tendencies. Wagner was an intellectual giant among men, and his works are amazingly grand, yet they unfortunately are, in a certain sense, responsible for much bad singing and not a little injury to fine voices. First of all, Wagner's operas are, in their present form, too long. To sing these compositions night after night is beyond human powers, even in the case of those of the most perfect musical and technical training. If they were divided into two, and one half sung on one evening and the other on the next, it would be a gain for the public and the artists. It is impossible for even the musically cultivated to absorb and assimilate the whole of such an opera as "Siegfried" or "Tristan and Isolde" in one evening, and it is too much to expect any artist to sing them through without a rest. Again, they call for such strong accents, such deep and strenuous breathing, that the artist impersonating a hero or a god or goddess is put to a degree of exertion that is too great for human powers when continued for more than a very moderate period; besides, there is a temptation to a wrong use of the larynx--a forcible _coup de glotte_, or attack--that is exceedingly dangerous, and has injured many voices and ruined others. The man or woman who would sing Wagner's greater music dramas should, in addition to a strong physique, be master of a wonderfully perfect technique. These operas should never be attempted by very young singers of either sex, and especially not by very young women. They are for the powerful, the mature, the perfectly trained, the experienced. Turning to some special faults, we would warn against the "scoop," the excessive use of the _portamento_, or glide, so common a fault at the present time, and the _vibrato_ and _tremolo_.
