I'm writing a script for a children's production about music history, and I want to provide the audience with an authentic experience by encouraging them to uphold the concert etiquette of each music era. This particular section/question is related to early Italian opera.

Specifically, did the audience stand? Or were the people seated? Did they ever stand up during performances at any specific points?

Was clapping a thing? If so, was it in-between every song? After arias? Only at the end? Did the audience ever boo? Throw tomatoes at performers? (I know -- silly, but send help!)

Were there any specific do's and don't's? For example, nowadays it's inappropriate to clap between movements in a sonata.

I'm a musician myself with a degree in piano performance so I'm well-versed in music theory, terminology, and general history. Opera history, unfortunately, was never my forte. I tried referencing my old history textbook from college, but found no help there. Quick google searches yielded nothing specific. Just lots of general opera history, but nothing about audience etiquette.

Thanks in advance!
