The peculiar character of Wagner's word-drama next arouses critical interest and attention. The composer is his own poet, and his creative genius shines no less here than in the world of tone. The musical energy flows entirely from the dramatic conditions, like the electrical current from the cups of the battery; and the rhythmical structure of the _melos_ (tune) is simply the transfiguration of the poetical basis. The poetry, then, is all-important in the music-drama. Wagner has rejected the forms of blank verse and rhyme as utterly unsuited to the lofty purposes of music, and has gone to the metrical principle of all the Teutonic and Slavonic poetry. This rhythmic element of alliteration, or _staffrhyme_, we find magnificently illustrated in the Scandinavian Eddas, and even in our own Anglo-Saxon fragments of the days of Caedmon and Alcuin. By the use of this new form, verse and melody glide together in one exquisite rhythm, in which it seems impossible to separate the one from the other. The strong accents of the alliterating syllables supply the music with firmness, while the low-toned syllables give opportunity for the most varied _nuances_ of declamation. The first radical development of Wagner's theories we see in "The Flying Dutchman." In "Tanhhaeser" and "Lohengrin" they find full sway. The utter revolt of his mind from the trivial and commonplace sentimentalities of Italian opera led him to believe that the most heroic and lofty motives alone should furnish the dramatic foundation of opera. For a while he oscillated between history and legend, as best adapted to furnish his material. In his selection of the dream-land of myth and legend, we may detect another example of the profound and _exigeant_ art-instincts which have ruled the whole of Wagner's life. There could be no question as to the utter incongruity of any dramatic picture of ordinary events, or ordinary personages, finding expression in musical utterance. Genuine and profound art must always be consistent with itself, and what we recognize as general truth. Even characters set in the comparatively near hack-ground of history are too closely related to our own familiar surroundings of thought and mood to be regarded as artistically natural in the use of music as the organ of the every-day life of emotion and sentiment. But with the dim and heroic shapes that haunt the border-land of the supernatural, which we call legend, the case is far different. This is the drama of the demigods, living in a different atmosphere from our own, however akin to ours may be their passions and purposes. For these we are no longer compelled to regard the medium of music as a forced and untruthful expression, for do they not dwell in the magic lands of the imagination? All sense of dramatic inconsistency instantly vanishes, and the conditions of artistic illusion are perfect. "'Tis distance lends enchantment to the view, And clothes the mountains with their azure hue."
