It is not easy, even for those who were aware from the very first that Strauss was not the spirit "pardlike, beautiful and swift" and that there always were distinctly gross and insensitive particles in him, to recognize in the slack and listless person who concocts "Joseph's Legende" and the "Alpensymphonie," the young and fiery composer, genius despite all the impurities of his style, who composed "Till Eulenspiegel" and "Don Quixote"; not easy, even though the contours of his idiom have not radically altered, and though in the sleepy facile periods of his later style one catches sight at times of the broad, simple diction of his earlier. For the later Strauss lacks pre-eminently and signally just the traits that made of the earlier so brilliant and engaging a figure. Behind the works of the earlier Strauss there was visible an intensely fierily experiencing being, a man who had powerful and poignant and beautiful sensations, and the gift of expressing them richly. Behind the work of the latter there is all too apparent a man who for a long while has felt nothing beautiful or strong or full, who no longer possesses the power of feeling anything at all, and is inwardly wasted and dull and spent. The one had a burning and wonderful pressure of speech. The other seems unable to concentrate energy and interest sufficiently to create a hard and living piece of work. The one seemed to blaze new pathways through the brain. The other steps languidly in roadways well worn. He is not even amusing any longer. The contriver of wonderful orchestral machines, the man who penetrated into the death-chamber and stood under the gibbet, has turned to toying with his medium, to imitating other composers, Mozart in "Der Rosenkavalier," Haendel in "Joseph's Legende," Offenbach and Lully (a coupling that only Strauss has the lack of taste to bring about) in "Ariadne auf Naxos." He has become increasingly facile and unoriginal, has taken to quoting unblushingly Mendelssohn, Tchaikowsky, Wagner, himself, even. His insensitivity has waxed inordinately, and led him to mix styles, to commingle dramatic and coloratura passages, to jumble the idioms of three centuries in a single work, to play all manner of pointless pranks with his art. His literary taste has grown increasingly uncertain. He who was once so careful in his choice of lyrics, and recognized the talents of such modern German poets as Birnbaum and Dehmel and Mackay, accepts librettos as dull and inartistic and precious as those with which Hofmannsthal is supplying him, and lends his art to the boring buffooneries of "Der Rosenkavalier" and "Ariadne auf Naxos." Something in him has bent and been fouled.
