Answer:
repetition
Explanation:
Repetition is a technique in which the musical notes and musical passages are repeated. It exposes the humans' ears to the rhythm created through repetition of the music. The tune, music, and the harmonies are recognized by the human ears when they are exposed repeatedly. Music has a lasting effect in the ears and mind because of its repeated exposure.
From my experience, some good ways to involve your audience in a theatrical performance, is to have them talk back. Ask them a question, and then they can all shout an obvious universal answer. For example, the performers may say "When I say Brainly, you say Yay! Brainly--" then they can respond. Or, you can say, non directly, but to make it seem like your speaking and interacting, you can say "hey, kids!" or, "parents, are we having fun, tonight?" or things like that. I hope that I helped :)
