Step-by-step explanation:
Performance art is a form of art in which the artist becomes part of the artwork itself, often involving live performances that can be interactive and include the viewer. It challenges the boundaries between disciplines, genders, private and public, and everyday life and art. Performance art can take place in any venue or setting and can involve any length of time. An example of performance art is Marina Abramovic's famous piece called 'The Artist is Present' where she sat silently and made eye contact with visitors at the Museum of Modern Art in New York for a total of 736 hours over the course of three months.
