what final gift does juliek give to the audience of dying and dead men?

Many men are thrown on top of each other in the rush to enter the barracks. Many men are either dying or dead. Elie notices that he has been thrown on top of Juliek the musician. The crush of men is suffocating but amidst the death and dying the sound of Juliek’s violin can be heard; the music is his final gift. Eliezer falls asleep to this music. When Elie wakes he finds Juliek dead and his violin smashed.
