When friends who aren’t regular goers to classical music performances accompany me to concerts, they sometimes ask if there are certain regulations they have to follow. Since I am not the one making up the rules, I usually just tell them to enjoy. Yet apparently, there ARE existing unspoken rules. For example, as my colleague Rachel Deloughry pointed out in her article 'Classical concert etiquette: Applause!': in classical music, not only is it frowned upon to clap between movements of a concerto or symphony, but it is also necessary to leave an appropriate amount of silence after the last note, to savour that final cadence, before finally showing your appreciation.
