 Some recent efforts have paid less attention to symphonic form and more to programmic intent. Hans Werner Henze wrote his 1997 Ninth Symphony in seven movements, basing the structure of the symphony on the novel The Seventh Cross by Anna Seghers. The novel recounts the flight of seven fugitives from a Nazi prison camp, the seven crosses symbolizing the seven death sentences; the ordeal of the one prisoner who makes it to freedom becomes the crux of the text. Penderecki's Seventh Symphony, subtitled "Seven Gates of Jerusalem" and originally conceived as an oratorio, is not only written in seven movements but, musicologist Richard Whitehouse writes, is "pervaded by the number' seven ' at various levels." An extensive system of seven-note phrases binds the work together, as well as the frequent use of seven notes repeated at a single pitch. Seven chords played fortissimo bring the work to a close.
