I have attended concerts at BBC recording studios. Before the performance begins, the audience, members of the public, are asked to be very still and silent, so as not to spoil the recording or live broadcast. The audience is politely requested to be so silent that one feels that even the sound of breathing might disturb the event.
With the exception of one western classical music concert in Bombay, audience disturbance is well tolerated at concerts I have attended in India. Pepole arrive and leave the auditorium whenever they feel like. They chat and take photos and often mover from one part of the auditorium to another.
Once, I attended a musical performance that was being relayed ‘live’ on All India Radio. Unlike the BBC recordings and live broadcasts, the audience was far from placid. Throughout the event, there were disturbances as described above, but no one seemed in the slightest disconcerted .
But, all is no longer well with British audiences. Recently, I have been to a few classical music performances in London, at which there has been applause at inappropriate places in the music. An example of this is clapping at the end of a movement of a symphony, rather than at its ending. Maybe, orchestras are getting used to this, but I find it a bit disconcerting.
