Why did juliek choose to play beethoven on his violin in the barracks when they arrive at gleiwitz

When they finally arrive at Gleiwitz, they are crowded into barracks, and Eliezer feels like he is going to be suffocated by the mass of people lying on top of him. People are crushing each other to death because it is so crowded, and Eliezer suddenly finds himself on top of Juliek, a boy who played the violin in the band at Buna. Eliezer is glad that Juliek is still alive and shocked to discover that he brought his violin with him. Then Eliezer begins to be suffocated by a man on top of him and has to fight his way out to get some air. He calls to his father, who is also still alive. That night Juliek miraculously extricates himself from the tangle of bodies and begins to play Beethoven soulfully on his violin. The music is so pure amidst the silence of the night, and Juliek puts his whole self and being into his music, which is only heard by an audience of dead and dying men.
