In this chapter, we will focus on performance as an aesthetic orcommunicative event that unfolds at a specific time and in a specific space set apart from the social world. Not only people come together in a performance, bu talso many different kinds of materialities and media. In the unique moment ofperformance that unfolds in time and space, the performer interacts with anaudience but also with other objects: props such as the famous skull thatHamlet holds in his hand or technical devices such as the microphone in astand-up act. In this chapter, we will look closely at how different kinds ofbodies and objects interact in a performance and at how the presence and emergence of an event interact with mediation and transmediation. Pantomimes, stand-up comedy acts, drama and music concerts can be understood as different qualified media types that take place in the context of different architectural framings that already in themselves indicate which conventions areat play, what kind of performance the audience should expect and what kind ofresponse is expected from the audience.
