To recapitulate, then, for a moment: Wagner's theory of the ideal music-drama is sound enough, but neither he nor any of his successors has been able to realise the theory in practice. In every combination of music with the other arts it must of necessity play the leading rôle, because of the greater expansiveness and superior warmth of its expression.[414] As Wagner saw, it will tolerate no text but one that is thoroughly musical in essence—that is to say, one that is so purely emotional throughout that at no time can we feel that in order to associate with it music has had to descend from its ideal sphere. It is in the process of making the action clear to the spectator that opera generally has to admit certain elements that drag music down from its high estate. We have therefore at present two chief forms of the association of poetry and music—the opera, in which actual characters, using actual words, are shown to us in the actuality of the stage, and the symphonic poem, in which we are given not the characters but the emotions of the characters, and not the scene but an imaginative suggestion of the scene, while the general nature of the subject is communicated to us by means of a printed explanation or a title. This necessity of putting the hearer en rapport with the story by a device that stands outside the music seems to many people an ineradicable flaw in the symphonic poem; a work of art, they say, should be self-contained, and opera, with all its admitted faults, has the virtue of being its own explanation. I do not think, however, that this matter is so simple as it looks.
Closer analysis will show first of all that many apparently self-contained musical works are as greatly in need of verbal expression as a symphonic poem, and secondly, that in the full sense of the term hardly any opera or drama can be said to be wholly self-explanatory, inasmuch as, at every hearing of it except the first, we witness the unfolding of the earlier stages of the action with a knowledge of the later stages, and are thus as effectually adding something from an outside source to the visual and auditory impressions of the moment as when we follow a symphonic poem with the story in our minds that we have just read in the programme book. What real difference, for example, is there between the frame of mind in which we listen to the Tannhäuser Overture and that in which we listen to Ein Heldenleben? In each case we are conscious that the music is not self-existent and self-explanatory, but depends for its full intelligibility on our knowledge of the characters and incidents upon which it is based. We get this knowledge in the case of Ein Heldenleben from a book; in the case of the Tannhäuser Overture we get it from our experience of the opera on the stage.[415] What essential difference is there between the two cases? In each of them we have to rely upon experience outside the work itself in order to grasp the full meaning of it. The Tannhäuser Overture and other works of that class are, in fact, artistic solecisms. No one, surely, will contend that at the first performance of Tannhäuser the Overture conveyed its poetic meaning to the audience any more clearly than a performance of Ein Heldenleben would do without a literary explanation of its contents. The Overture does not explain the opera, but is explained by it, and it is consequently absurd to play it first. It only happens to come first because the old practice of having an orchestral introduction to an opera was unthinkingly retained long after the character of the introduction had so altered that there was no longer any sense in its use. The purpose of the Overture originally was simply to play the audience into their seats. We see it performing this function in an overture like that to the Messiah: the music has nothing to do with the oratorio, and any one of a hundred other orchestral introductions would do just as well. But when opera composers began to make the overture a summary of the opera itself, they entered upon a course that ultimately made it an absurdity. In so far as the overture sums up the opera, and therefore depends for its intelligibility on a knowledge of the opera, it ought logically to be played not at the commencement of the evening, but at the end. Modern composers have instinctively recognised the truth of all this, and the operatic overture is now virtually abolished; there is none, for instance, to Salome, Elektra, or Pelleas and Melisande.
All the overtures, then, that epitomise the opera with which they are connected are in the same category as the symphonic poem; for an understanding of the literary basis of them we have to go to a source outside themselves. The theory that a piece of music is bad music unless it is "self-sufficing" and "self-explanatory" is a mere nightmare of the arm-chair æsthetician. There are thousands of pages in Bach that only yield up their full secret to us when we get some outside light upon the sequence of poetic ideas in his mind at the time of writing. This is the case with many of the chorale preludes, for example. But Bach's music is often rich in a kind of allusive symbolism greatly resembling Wagner's use of the leading motive, though it is bolder than that, inasmuch as the musical symbol has not been made familiar to us by a previous definite use of it in the same work of art. In the Christmas Oratorio Bach sets the words of a chorale addressed to the infant Jesus to the music of another chorale that was already associated in the minds of the congregation with the Passion—thus in a flash bringing the death of the Saviour into the same mental picture as the birth.[416] The chorale fantasia which the blind old man dictated to his pupil Altnikol a few days before his death united the music of the hymn "In our hour of direst need," with the words of "I come before thy throne." And who can forget the effect, comparable to some of the most thrilling of those that Wagner makes with his leading motives, of the trumpet pealing out with the melody of "Great God, what do I see and hear! The end of things created" in the midst of the bass recitative describing the terrors of the Day of Judgment (in the cantata Wachet, betet). Bach anticipated, as he did most things in modern music, the Wagnerian use of the leading motive, the function of which is to suggest to the hearer's imagination another idea simultaneously with the one the music is explicitly expressing. I think Bach would have smiled at anyone who chose to object that his chorale in the Christmas Oratorio was not self-sufficing, inasmuch as it depended for its affecting double meaning upon knowledge that the hearer had gathered elsewhere. He would probably have been satisfied with the unshakable fact that the hearer had this knowledge, and that it was therefore quite safe to rely on his making use of it. Surely the composer of the symphonic poem and allied forms is also justified in trusting occasionally to his auditors' outside knowledge of the subject of his work. Is there anything less legitimate in Strauss's trusting to our imagination to summon up at performance the scenes and the figures of Don Quixote, than there is in Wagner's trusting to it, during the Tannhäuser or Meistersinger Overture, to summon up the scenes and figures of the opera? I have already pointed out that in his music-dramas Wagner is continually asking us, by means of recurrent leading motives, to visualise more than is actually set before us on the stage—thus flying in the face of his own theoretical arguments. It only needs to be added that he also relied, at times, as much as the writer of symphonic poems does, upon the hearer's or spectator's knowing more about the course of the drama than has been revealed to him in the drama itself. How do we know, for example, that the "Sword" motive in the final scene of the Rhinegold is a "Sword" motive at all? How do we know the train of thought running through Wotan's mind at this point as he looks into the future? Simply by antedating the information we have gained from the later dramas of the Ring. At the time the "Sword" motive is first heard there has never been the slightest suggestion of the sword that is to help to lift the curse from the gods; not only Siegfried but Siegfried's parents are as yet unborn. Again, the phrase that Tannhäuser sings to the words "Ha, jetzt erkenne ich sie wieder, die schöne Welt der ich entrückt" in the first Act of the opera is explained only by the association of it with Elisabeth and the Hall of Song in the second Act. Anyone with a knowledge of the Wagnerian operas can multiply these instances for himself.
Does not everything, in fact, point to the impossibility of our listening to any performance of a drama or opera, except the first one, with a mind that is absolutely a clean slate? Are we not always drawing consciously or unconsciously upon our store of acquired knowledge of the work, and blending this with the visual or auditory impressions of the moment? Do we not all know, long before it happens, that the screen will fall down at a certain climactic point in the School for Scandal and show us Lady Teazle hiding behind it? Is not our appreciation of all the dialogue of this scene whetted by our knowledge—gained from "outside" sources—of what is going to happen at the end of it? The instructed spectator or reader invariably keeps looking ahead, his interest or delight in what is occurring at the moment being intensified by what may be called anticipatory memory. It is only at the first time of reading Tom Jones that we can be in the slightest doubt as to who is the hero's mother. The ever-present clue to the solution of the mystery does not spoil our pleasure, however, in the second and subsequent readings; nay, it rather adds to it, for it makes us conscious of a number of cunning strokes of construction that we had not noticed at the first reading. At the second and every subsequent performance of Mr. John Galsworthy's The Pigeon a thrill of horror goes through us at the exit of Mrs. Megan in the second Act, for we know—what we did not know at the first performance—that she means to throw herself into the river; and for this reason the second performance necessarily makes a profounder effect on us than the first. I take it, then, that an exaggerated importance can be attached to the principle of art being "self-sufficing" and "self-explanatory" at the first time of hearing or seeing; the subject is a far more complex one than the amateur æstheticians have imagined. They had only to turn to the Greek drama to see a form of art in which deliberate advantage was taken by every author of the fact that the audience had an "outside" knowledge of the characters and events of the play. The Greek drama, broadly speaking, did not rely, as ours does, on the effect of a slow unfolding of a complicated plot—the main art of which consists in first of all giving the audience something to hunt for and then finding it for them. The Greek drama was based on a myth or a legend every detail of which was known to every member of the audience. At a first performance, therefore, the audience would be in precisely the same position as a modern audience is when it reads in its programme-book the analysis of a new symphonic poem that is about to be performed. And this knowledge, so far from diminishing the audience's enjoyment of the drama, actually intensified it, and permitted to the author an amount of subtle psychological allusion that can only be compared with the effects of the leading motive in modern opera. When Clytemnestra, for instance, in Æschylus's drama, greets Agamemnon with falsely-fawning words, the thrill that ran through the Athenian audience came not from any feeling of foreboding inspired by the visible situation or the actual words, but from its outside knowledge that all this was feigning, and that the hounds of death were already hot on the track of the unsuspecting king. Wagner would have flashed the same light upon Clytemnestra's words by means of an orchestral motive. An Athenian, again, at the first performance of the Œdipus Rex, must have known the whole of the story from the beginning. There could be for him none of the cumulative surprise at the slow unravelling of the web that we feel at a first reading of the tragedy; rather did he accompany the first blind steps of Œdipus with a pity born of the knowledge—the outside knowledge—of the doom the gods had woven for him.
