The last movement begins with a ringing _pomposo_, and I cannot explain its meaning better than by quoting Mrs. MacDowell's words: "Mr. MacDowell's idea was, so to speak, as follows: He wished to heighten the darkness of tragedy by making it follow closely on the heels of triumph. Therefore, he attempted to make the last movement a steadily progressive triumph, which, at its climax, is utterly broken and shattered. In doing this he has tried to epitomize the whole work. While in the other movements he aimed at expressing tragic details, in the last he has tried to generalize; thinking that the most poignant tragedy is that of catastrophe in the hour of triumph." The third sonata (op. 57) is dedicated to Grieg and to the musical exploitation of an old-time Skald reciting glorious battles, loves, and deaths in an ancient castle. The atmosphere of mystery and barbaric grandeur is obtained and sustained by means new to piano literature and potent in color and vigor. The sonata formula is warped to the purpose of the poet, but the themes have the classic ideal of kinship. The battle-power of the work is tremendous. Huneker calls it "an epic of rainbow and thunder," and Henry T. Finck, who has for many years devoted a part of his large ardor to MacDowell's cause, says of the work: "It is MacDowellish,--more MacDowellish than anything he has yet written. It is the work of a musical thinker. There are harmonies as novel as those we encounter in Schubert, Chopin, or Grieg, yet with a stamp of their own." The "Sonata Eroica" (op. 50) bears the legend "Flos regum Arthurus." It is also in G minor. The spirit of King Arthur dominates the work ideally, and justifies not only the ferocious and warlike first subject with its peculiar and influential rhythm, but the old-fashioned and unadorned folk-tone of the second subject. In the working out there is much bustle and much business of trumpets. In the reprise the folk-song appears in the tonic minor, taken most unconventionally in the bass under elaborate arpeggiations in the right hand. The coda, as in the other sonata, is simply a strong passage of climax. Arthur's supernatural nature doubtless suggested the second movement, with its elfin airs, its flibbertigibbet virtuosity, and its magic of color. The third movement might have been inspired by Tennyson's version of Arthur's farewell to Guinevere, it is such a rich fabric of grief. The finale seems to me to picture the Morte d'Arthur, beginning with the fury of a storm along the coast, and the battle "on the waste sand by the waste sea." Moments of fire are succeeded by exquisite deeps of quietude, and the death and apotheosis of Arthur are hinted with daring and complete equivalence of art with need.
