The passage discusses the relationship between audiences and performers in music and theatre. The writer used to think opera was primarily theatre, but working at an opera house showed that the music comes first. Theatre audiences have different expectations than music audiences - they are less impressed by acting skills and see the work as closer to everyday life. However, both audiences appreciate challenging material. The writer believes music could learn from theatre about having a more equal relationship with audiences. Strict conventions in music performances can create hierarchy, while interruptive applause shows insensitivity.
