Ornaments, such as _appoggiaturas_ and _turns_, _roulades_, _trills_, &c., are to be used only with taste and care. The old Italian compositions, which were so arranged as to show the voice in its fullest brilliancy, have their ornaments commonly in such phrases as were to be first sung several times in a simpler way. In the frequent repetition of the same melody and words, those places were designated by so-called _firmates_, where it was permitted to the artist to introduce embellishments according to his own taste. In German arias embellishments are allowed to be introduced according to the taste of the singer, only, however, with the greatest care; but in German ballads not at all. And yet we often hear artists, who have acquired a certain flexibility of voice, introducing their little trickeries in the most inappropriate places. But none of these aids to expression are to be used so often as to become mere mannerisms. Only when employed in due measure can they have an æsthetically fine effect. As so much depends upon the taste of the singer, it is necessary that he should, above all things, have a thorough appreciation of the sentiment which is to find expression in the piece, and seek to make it his own, and then the ornament is to be introduced only where it accords with the sentiment, that is, where it is appropriate. The two greatest artists of the present day, Lind and Stockhausen, whose expression is perfect, take great pains to understand the composition thoroughly, and in this way to be fully imbued with the sentiment. Without the animation of a soul, singing fails of all effect upon the hearer, and is ordinary and wearisome. But this animation must be with understanding and taste--i.e., æsthetically beautiful. For the beautiful continues beautiful and true only as long as it is in proportion and not exaggerated--only while those fine lines are not transgressed where it begins to be untrue, that is, affected and ridiculous.
