Of the ideas which lie behind the music of Strauss less can be said in opposition now than could be said five years ago. Then we knew Strauss as the writer of "Don Juan," an attempt to put into music the sensuality of a libertine, his final satiety, his utter coldness of heart; of "Death and Apotheosis," a weird endeavor to portray with an orchestra the horrors of dissolution, the gasps, the struggles, the death-rattle, the _tremor mortis_; "Till Eulenspiegel's Merry Pranks," a study in musical depiction of wandering vulgarity, of jocular obscenity, a vast and coruscating jumble of instrumental cackles about things unfit to be mentioned. We felt that the nineteenth century was closing with something like midsummer madness in art. With Ibsens, Maeterlincks, and Strausses plucking like soulless ghouls upon the snapping heart-strings of humanity, treating the heart as a monochord for the scientific measurement of intervals of pain, and finally poking with their skeleton fingers in the ashes of the tomb to see if they could not find a single smouldering ember of human agony, we had attained a rare state of morbidity in art. We felt that when Art had turned for her inspiration to the asylum, the brothel, and the pesthouse, it was time for a new renaissance. Strauss was our musical Maeterlinck, our tonal Ibsen. Vague, indefinable fancies, grotesque and monstrous mysticisms, gaunt shapes and shapeless horrors, seemed to be his substitutes for clean, strong, pure ideals; and when he set to music Friedrich Nietzsche's "Thus Spake Zarathustra," the philosophy of the solution of "world riddles," we thought he had utterly gone mad. For in this work we found the highest skill in the development and polyphonic treatment of leading motives devoted to an attempt to make music lecture on metaphysics, when all the time it was perfectly obvious that without reading Nietzsche's book no one could have any notion of the composer's intent. The mastery of orchestration and of the technics of composition shown in this work convinced thoughtful critics that Strauss was not to be sniffed out of consideration. Here was a force to be reckoned with in musical progress, even though it was mistakenly wielded.
