The rhythmic notes of jolly marches

"Humanity had lost its voice: the women with the bricks were mute; the people on the right walked silently along the road to the crematorium. But in a separate corner of the camp the orchestra had been set up. The rhythmic notes of jolly marches filled that great silence and galvanised the most tense, worn nerves. 

"'Madness!' I said to myself. 'This is where madness begins'." 

-Giuliana Tedeschi, There Is a Place on Earth: A Woman in Birkenau
