The atmosphere on the rooftop was tense and anxious.
The crowd below sang with growing vigor, the number of people joining the chorus increasing, some even straining their voices hoarse yet unwilling to stop.
A minority stood aside, indifferent, even going so far as to heckle the girl to jump quickly, but the majority were more concerned about the little girl's safety.
Previously, everyone stood downstairs, partially out of curiosity, but also with the hope that they might be able to help.
Now, seeing that they might actually be able to contribute, everyone was extraordinarily enthusiastic.
Music, inherently a powerful means of emotional expression, had filled those firefighters and police officers who had just finished deploying the safety air cushion below, with a sense of being moved, even if they didn't know whether the little girl upstairs was comforted.
No one noticed that the person who first suggested the mass singing had disappeared without a trace.
