HORACE, _Ars Poetica_. Mr. Strauss has been acclaimed as an explorer, a pathfinder in the wilderness of new art. But after all he is simply a product, or perhaps it would be more exact to say a result; for the trend of musical art in the past century was toward representation. But the attempts of the early composers were in the line of descriptive music, which is a species of mimetics. The transfer of peculiar sounds and characteristic sound-motions, as in the cases of whistling wind and undulating forest billows, to the musical canvas, is a simple and natural process. It pleases the most superficial mind by the translation of one art into terms of another. To "paint" in sounds, as the musicians term it, is a pretty and poetic fancy. It is like the poet's use of tone-speech to imitate qualities or motions. It is the onomatopoetic in music. Sometimes it is the paronymous. We are all cultivated savages. The primeval hordes of Europe had their rude rhythms and their inarticulate cries, which were as music to their ears. Significance was attached to these sounds wholly because of their external resemblance to something lying in a different plane of human experience. We have refined and extended the scale and have attuned our ears and our spirits to higher tones. We hear triads in stones, scales in running brooks, and chords of the diminished seventh in everything. How long was it before the musicians ceased to content themselves with their tone pictures of ocean waves and murmuring streams? Surely, it was not long after Monteverde found the rhythmic and instrumental equivalents for the galloping of horses and the crashing together of gallant and knightly combatants that the dream of joy or woe, uttered in songs without words, entered the minds of composers. Monteverde's lament of Arianna showed that the plaint of a sorrowing heart might be most musical, most melancholy. Doubtless, as the indolent Venetian gondolier hummed the melody and forgot the words through the shining avenues of the island city, the thought came dimly to him, as it did clearly to the musician, that the tune was sad and saddening, even without the text. But not till the time of Beethoven was a direct and explicit effort made to paint soul pictures in wordless music. Beethoven was indeed the regenerator of instrumental art, in that he demonstrated with splendid and convincing power in his later symphonies that the classic sonata form could sing the weal and woe of humanity with eloquence as noble as that of the opera aria aided by the explanatory comment of its own verses. Beethoven, however, contented himself with broad outlines. He sang passion, joy, grief, resolution, courage, force; but never did he essay to impart to his music the virtue of an explanation. The fifth symphony explains itself and it asks no aid from without. It does not lean back against a wall of text for its support.
