oratorio
An oratorio is a grand assembly of chorus and musicians replaying sacred themes in an endless loop of solemnity. The libretto is declaimed with such gravity that performers find themselves under silent orchestral interrogation. Musicians endure what amounts to a marathon in the name of spiritual salvation. Audiences offer reverent applause whose true intent few ever question. Immersed in the majestic illusion, attendees inevitably exit pondering where to finally get some sleep.
