If Nietzsche considered the poem a vaporous background for the passionate musical mosaic of Tristan and Isolde, what would he have thought if he could have heard the tonal interpretation of his Also Sprach Zarathustra, as conceived by the mathematical and emotional brain of Richard Strauss? I recall the eagerness with which I asked an impossible question of Frau Foerster-Nietzsche when at the Nietzsche-Archive, Weimar, in 1904: Is this tone-poem by Richard Strauss truly Nietzschean? Her tact did not succeed in quite veiling a hint of dubiety, though the noble sister of the dead philosopher was too tender-hearted to suggest a formal criticism of the composer's imposing sound-palace. It is not, however, difficult to imagine Nietzsche, alive, glaring in dismay and with "embellished indignation" as he hears the dance theme in Zarathustra. Nor would he be less surprised if he had suddenly forced upon his consciousness a performance of Claude Debussy's mooning, mystic, _triste_ Pélléas et Mélisande, with its invertebrate charm, its innocuous sensuousness, its absence of thematic material, its perverse harmonies, its lack of rhythmic variety, and its faded sweetness, like that evoked by musty, quaint tapestry in languid motion. (Debussy might have delved deeper into churchly modes and for novelty's sake even employed pneumes to lend his score a still more venerable aspect. Certainly his tonalities are on the other side of diatonic and chromatic. Why not call them _pneumatic_ scales?) Surely Nietzsche could not have refrained from exclaiming: Ah! the pathos of distance! Ah! what musical sins thou must take upon thee, Richard Wagner! Strauss and Debussy are the legitimate fruits of thy evil tree of music! Miserably happy poet, like one of those Oriental wonder-workers dancing in ecstasy on white-hot sword-blades, the tears all the while streaming down his cheeks as he proclaims his new gospel of joy: "_Il faut méditerraniser la musique._" Alas! the pathos of Nietzsche's reality. Reality for this self-tortured Hamlet-soul was a spiritual crucifixion and a spiritual tragedy. III ANTICHRIST?
