Vocalization-OK Guidelines
Regarding vocalizing during performances, you must be wearing a mask of nonwoven fabric (I presume this just means "approved covid mask").
Singing along may be done at conversational volume. Moreover, as for cheering, when the performers take the stage and when the concert ends, it is permissible to call out once.
This notwithstanding, please refrain from any loud, continuous singing or cheering that might perturb the tranquility of your fellow patrons.
Or perhaps, was it banned purely with an eye toward the preservation and prolongation of the patrons' individual and collective equanimity?
