This movement is a series of wild and intricate episodes connected with a series of trumpeting B octaves that alternate registers. Also of note is a section that returns over the course of the work for gradual effect with propulsive left hand octaves, not unlike Liszt’s “Funerallies.” The work builds to an enormous climax with an organic section of fast repeated chords that ultimately give way to an augmented reiteration of the B-octave beginning.
