Everyone is different. Sometimes it's very exciting; sometimes very scary.
All of us love applause, and so we should - it means that the listener likes us!
The sheer force of the music calls for a wild audience reaction.
We seem to have set up some very arcane rules as to when it is actually OK to applaud.
Sometimes I wish that applause would come just a bit later, when it is so beautifully hushed that I feel like holding my breath in the silence of the end.
Applause should be an emotional response to the music, rather than a regulated social duty.
