Carl Van Vechten,
The Russian Review
(1916)
“ Strauss, following Wagner's theory of the leit-motiv, rounded out the form of the tone poem, carried the principle of representation in music a few steps farther than his master, gave new colors to old instruments, and broadened the scope of the modern orchestra so that it might include new ones; in one of his symphonies Gustav Mahler was content with 150 men! Moussorgsky (although his work preceded that of Strauss, the general knowledge of it is modern) , working along entirely different lines, strove for truthful utterance and achieved a mode of expression which usually seems inevitable. ”
