But, if great powers are required by the composer of an opera, so also is it necessary that those who are to make known its meanings fully--especially those who are to interpret its leading parts--should possess, as singers and actors, more, to say the least, than ordinary abilities; and those who, in their capability for complete, soulful sympathy with the author's aims, who form, in fine, the very embodiment of the latter's ideals, certainly deserve to stand next to him in greatness. Generally the brightest vocal stars have shed their effulgence upon the operatic stage: here these singers have found the widest range for their extensive powers of voice and dramatic action. The part of a performer in opera (and here I refer not alone to one who acts the leading _role_) is a most exacting one; for the artist must unite in himself the qualities of both the singer and the actor. While called upon to demonstrate with proper melody of voice and expression the meaning of the music of the opera, he is also required to portray by suitable dramatic movements its corresponding meaning as found in the libretto. These remarks apply more particularly to those who constitute the _dramatis personae_ in operatic presentation. Of course we do not forget the very important aid afforded by those who are included in the pleasing chorus, nor those who by instrumental accompaniment add to the charm of--in fact, give indispensable support to--the whole performance. It would perhaps be superfluous to here dwell, at least more than incidentally, upon the deep pleasure enjoyed by the lovers of music and of dramatic art when witnessing the performance of a good opera. At such a time their truly musical souls enjoy a delicious, a sumptuous feast of melody; while the kaleidoscopic prospect, formed by richly-costumed actors, and appropriate, beautiful scenery, fills them with delight. The harsh realities of every-day life are so much relieved by the poetic charms of the ideal, that they live amidst a scene of fairy-like enchantment. Nor does all that belongs to the bewitching occasion end with the regretted close of the performance; for "Music, when soft voices die, Vibrates in the memory;" And for days and days, nay, often throughout life, do the best melodies, the "gems of the opera," delightfully "haunt the memory," and awaken in the heart the most pleasing emotions. In all this, no more than a just tribute is paid to the noble genius of the composer, and the fascinating power of his faithful coadjutor, the lyric actor.
