It is in the boldly imaginative and unconventional arrangement of simple material that Strauss gets his most striking harmonic effects. Plain "triads" and "dominant sevenths," the small musical change of hack composers, turn to gold in his hands. The touchingly expressive cadence of Don Quixote's theme will illustrate. The material is of the most ordinary, yet the effect is magical and its dramatic appropriateness surprising. In the words of Mr. Arthur Kahn,[8] "These confused harmonic windings through which the central chords of the previously established key are reached, characterize strikingly the well-known tendency of Don Quixote towards false conclusions. He goes carefully out of the way of natural sequences and palpable facts, in order not to demolish therewith his fancy structures."
Strauss has carried this principle of the close juxtaposition of chords more or less foreign to each other, and even of different keys, to greater and greater lengths in his more recent works, and to the effects of "queerness" which result when these foreign tonal groups quickly follow each other, and of more or less extreme dissonance when they occur simultaneously, he owes much of the violently adverse criticism to which he has been subjected. Indeed, nothing has more retarded his general acceptance than these abrupt transitions and unaccustomed discordancies. The matter is of sufficient importance to intelligent appreciation of him to justify a brief digression here. For any composer who conceives music as a number of melodies proceeding together in greater or less amity, but preserving the measure of independence that individuality and vigorous movement demand—and Strauss is to a peculiar degree such a polyphonic composer—a certain amount of physical harshness at moments when the melodies happen to clash is not only unavoidable but positively desirable, as tending to throw each into relief. According to the degree of his experience the listener follows the composer in this respect: that is, he accepts with something more than passive endurance, yes, with active pleasure, the physically disagreeable clashes (dissonances) which by setting off the differing contours of the melodies emphasize for him their mental and emotional appeal; but not—and the point is of prime importance to the would-be music-lover—not if he does not follow the melodies, that is, not if he cannot hear consecutively as well as moment by moment—for it is only by following the threads, so to speak, that we can untangle the knots. Accordingly most untrained listeners dislike, probably, music that contains many of these knots, the presence of which makes it so interesting and exciting to the experienced ear. The woman who confessed to her piano teacher that she did not like Bach's Two-part Inventions because they were so "ugly" was not less cultivated but only more frank than many who have not discovered that Bach has to be heard "horizontally" (to borrow a figure from musical notation) rather than "vertically."
This gift of horizontal hearing is peculiarly necessary to anyone who would disentangle the tonal knots in which Strauss delights, working as he does with many more than two voices and with the vast fund of harmonic possibilities accumulated since Bach's day to draw upon. And he is not the man to use his resources timidly, or to make any concessions to laziness or inexperience in his listeners. Here is a reduction of a passage from "Ein Heldenleben" to its essential elements.
Figure VII.
The heavy brass gives the foundation harmonies; the strings and woodwind have an upward-moving melody, and the eight horns blare forth at the same time a slower-moving downward melody. If we read almost any single chord vertically, we shall find it has its measure of harshness, sometimes considerable. If we listen to the coherent voices, none of these dissonances will trouble us in the least. This is a very simple example of what Strauss is constantly doing in a far more complex way.[9]
It is a real difficulty in the way of Strauss appreciation that while only familiarity can enable us to follow the intricate windings of the threads that make up his gorgeously rich fabrics, frequent hearings of his later and more complex symphonic poems are not to be had, even in the large cities. In the meanwhile we have no recourse but piano arrangements, unsatisfactory for two reasons. In the first place, it is physically impossible to play with two hands even a respectable fraction of the melodies that Strauss delights to elaborate for two hundred; and four-hand versions are better only in degree, not in kind. Secondly, piano versions fail us precisely in this matter of unraveling dissonance, since by reducing a colored pattern to monochrome they diminish the salience of the lines we are trying to follow, and by juxtaposing in one tone-quality tones that in the orchestra are softened by difference of timbre they notably increase the physical harshness of the combinations. Obviously, then, we must be exceedingly chary of condemning Strauss, or any other composer, for orchestral dissonance that we have either become acquainted with insufficiently, or only through piano arrangements.
