Development of the arioso.
The aria supplanted.
Music and action.
Out of this style there grew within a decade something very near the arioso, and for all the purposes of our argument we may accept the melodic devices by which Wagner carries on the dialogue of his operas as an uncircumscribed arioso superimposed upon a foundation of orchestral harmony; for example, Lohengrin's address to the swan, Elsa's account of her dream. The greater melodiousness of the recitativo stromentato, and the aid of the orchestra when it began to assert itself as a factor of independent value, soon enabled this form of musical conversation to become a reflector of the changing moods and passions of the play, and thus the value of the aria, whether considered as a solo, or in its composite form as duet, trio, quartet, or ensemble, was lessened. The growth of the accompanied recitative naturally brought with it emancipation from the tyranny of the classical aria. Wagner's reform had nothing to do with that emancipation, which had been accomplished before him, but went, as we shall see presently, to a liberation of the composers from all the formal dams which had clogged the united flow of action and music. We should, however, even while admiring the achievements of modern composers in blending these elements (and I know of no more striking illustration than the scene of the fat knight's discomfiture in Ford's house in Verdi's "Falstaff") bear in mind that while we may dream of perfect union between words and music, it is not always possible that action and music shall go hand in hand. Let me repeat what once I wrote in a review of Cornelius's opera, "Der Barbier von Bagdad:"[F]
How music can replace incident.
"After all, of the constituents of an opera, action, at least that form of it usually called incident, is most easily spared. Progress in feeling, development of the emotional element, is indeed essential to variety of musical utterance, but nevertheless all great operas have demonstrated that music is more potent and eloquent when proclaiming an emotional state than while seeking to depict progress toward such a state. Even in the dramas of Wagner the culminating musical moments are predominantly lyrical, as witness the love-duet in 'Tristan,' the close of 'Das Rheingold,' Siegmund's song, the love-duet, and Wotan's farewell in 'Die Walküre,' the forest scene and final duet in 'Siegfried,' and the death of Siegfried in 'Die Götterdämmerung.' It is in the nature of music that this should be so. For the drama which plays on the stage of the heart, music is a more truthful language than speech; but it can stimulate movement and prepare the mind for an incident better than it can accompany movement and incident. Yet music that has a high degree of emotional expressiveness, by diverting attention from externals to the play of passion within the breasts of the persons can sometimes make us forget the paucity of incident in a play. 'Tristan und Isolde' is a case in point. Practically, its outward action is summed up in each of its three acts by the same words: Preparation for a meeting of the ill-starred lovers; the meeting. What is outside of this is mere detail; yet the effect of the tragedy upon a listener is that of a play surcharged with pregnant occurrence. It is the subtle alchemy of music that transmutes the psychological action of the tragedy into dramatic incident."
