In 1946 Hindemith, who became an American citizen in January of that year, composed the Requiem for Robert Shaw's Collegiate Chorale. Whitman's poem had been written on the death of Lincoln. Some parallel events at Roosevelt's death and the excellent interpretation presented Hindemith's work a great success.
The recent identification of the Jewish melody Gaza, which appears in large parts of the work, reveals a further meaning: It must be seen as Hindemith's musical reaction to the Holocaust, a reaction, whose effect is all the more penetrating and persuasive, because Hindemith himself never revealed the identity of the Gaza melody for the purposes of cheap publicity. Hindemith wrote a Requiem for the living (the survivors), who are obligated to remember and identify themselves with the victims and must transform this historical moment into an imperishable personal experience.
