Why was eliezer touched by the eerily poignant little corpse of the violin when hundreds of human corpses left him unmoved

Juliek's violin-playing disrupts the silence, this time filling the night with rare beauty and poignancy: "He played a fragment from Beethoven's concerto. I had never heard sounds so pure. In such a silence." Juliek's music is unusually touching and heartrending because he puts his whole being into his playing. After being denied his life, humanity, and future by the Nazis and after having becoming emotionally numb from his time in the concentration camp, Juliek takes everything that has been denied him and infuses it into his music: "He was playing his life. The whole of his life was gliding on the strings‹his lost hopes, his charred past, his extinguished future. He played as he would never play again."
