Step-by-step explanation:
Performance art refers to a usually unrehearsed event conceived and performed by artists and others, sometimes including viewers. It is an interdisciplinary form of art that can be scripted or unscripted, random or orchestrated, and can occur with or without audience participation.
A performance can involve the four basic elements of time, space, the performer's body or presence in a medium, and a relationship between the performer and the audience. It can take place in any venue or setting and for any duration of time.
Performance art challenges conventional social mores and artistic values by breaking down borders between disciplines, genders, and the private and public spheres. It follows no rules and often provokes and offends to incite political action.
