full_question: This work's main theme begins with an E-flat minor chord and alternates between major and minor chords for fourteen measures before reaching B minor. That theme, which opens this work in three-four time, reappears after the "death of Oates," and again in four-four in the Alla marcia moderato Epilogue. This work's "nature music" includes pianississimo thirty-second- note xylophone runs, and its third movement, "Landscape," climaxes with a fortississimo organ solo. Quotations from Shelley, the Psalms, Donne, and Coleridge are sometimes read between movements of this work, preceding an excerpt from a diary in which a man claims, "I do not regret this journey." Its first movement features a wordless women's chorus and a solo soprano, and the percussion ensemble includes "deep bells," celesta, and wind machine. For 10 points, name this symphony by Ralph Vaughan Williams based on a film score about Robert Falcon Scott's failed attempt to reach the South Pole.
