The Nazis featured uses of music that were intended to advance their own agenda of control and humiliation.  One way in which they perverted music in order to do this was through forced singing.  Nazi guards would often demand that their prisoners sing on command songs in unison as a show of the guards' strength and power over others.  Sometimes the songs would be in honor of the Third Reich, other times in deference to the camp, and sometimes in honor of the fatherland, Germany.  Guards used this musical approach to exhibit their sense of control and the victims' further dehumanization.  Music was also used to entertain the guards.  While the Nazis were horrific and represented the very essence of sadism, studies have shown that many Nazis were appreciative of fine music and sometimes the guards used members of the concentration camp to sing and play music that was artistically appealing to the Nazis.  The use of music and its varied applications provide another example of the wide ranging level of cruelty within Third Reich practices, and exposed in Wiesel's work.
