The line suggests that, despite the desolation of hell, the act of singing signifies resilience and the persistence of hope. It highlights how the human soul seeks expression, clinging to the power of song as a form of solace when faced with despair.

This sentiment underscores a central theme of the novel: the struggle against suffering and the search for redemption. Even in seemingly hopeless situations, the characters find ways to cope and maintain their humanity through music and shared experiences, illustrating the depth of human emotion and the importance of hope as a guiding force.
