Your question is rather vague, but here are some answers dealing with Greek theatre

When plays were preformed in classical Greece and Rome would the audience have shouted and jeered at the stage like they did at medieval and Renaissance plays? by u/XenophonTheAthenian

Did the average Greek citizen understand Greek Theatre and Poetry by u/Iphikrates and u/XenophonTheAthenian

Hi there! More can be said, but I've written a fair bit about Greek theatre on here before: you can check out everything I've written about it here (some answers were certainly of lesser quality than others, as I've gotten better and learned more since I started here). I think for an overview of topics, this collection of those write-ups should help:

• A general summary of how theatre most famously worked
• A look at the three main genres of Greek theatre (tragedy, comedy, and satyr plays)
• How were Ancient Greek tragedies perceived at the time?
• How often were Plays played in Ancient Greece
