But much has to be got through before this point is reached. First, we have the gorgeous prelude--the most brilliant Wagner wrote, and the last he was to write that has no thematic connection with any portion of the opera. Here we have no summary of the act, no hint of impending disaster and tragedy, but simply a joyous, rattling preliminary to the procession that escorts Lohengrin and Elsa to the bridal chamber. It starts off with immense spirit, the music leaping straight up, hesitating a moment on a cross-accent, then a noisy shake reaching its highest note, and after a clash of the cymbals sliding off into the more regular rhythm, broken slightly by occasional syncopations, in which the piece as a whole is conceived. The melody in the bass that follows, and the more tender strains of a middle section, are familiar to every one nowadays--in fact, so familiar that we are likely to overlook the intense originality of the whole thing. When we remember the course the drama has now to take, the tragic beauty of its close, we can perceive how exactly right Wagner's feeling was when he left the plan he adopted throughout the _Dutchman_ and _Tannhäuser_--the plan either of summing up or foreshadowing the ensuing scenes, or of making the prelude part of the first scene. Of course the music at the beginning of Act II is rather in the nature of an introduction than of a distinct prelude; but Act III is not prefaced by so much as that. Rather, it suggests that since Elsa and Lohengrin entered the church all has been rejoicing, and that we catch only the tail-end of the feast as the party comes on the stage.
