Normally classical music is set up so you have professionals on a stage and a bunch of audience - it's us versus them. You spend your entire time as an audience member looking at the back of the conductor so you're already aware of a certain kind of hierarchy when you are there: there are people who can do it, who are on stage, and you aren't on stage so you can't do it. There's also a conductor who is telling the people who are onstage exactly what to do and when to do it and so you know that person is more important than the people on stage.
