Participatory art requires of the artist that they either not be present, or that they somehow are able to recede far enough to become equal with the participants. This is the only way that participants might be offered the agency of creation; without this detail, participants will always respond within the domain of authority of the artist; they will be subjugated in this way, and the work will fail to be participatory. This detail is centrally important in asserting participation as a form in itself, and effectively differentiates participation from interactive, community based art and socially engaged art. Any of these techniques can include the presence of the artist, as it will not impinge upon the outcome of the work in the same way. There are various degrees of participation from nominal manipulation of an object like the wearable sculptures of
Lygia Clark to the relinquishing of the artist's body to the whims of the audience in the 1974 performance
Rhythm 0 by
Marina Abramović. New media theorist Beryl Graham has compared the varying degrees of participation in the arts to the eight rungs of power described in
Sherry Arnstein's "Ladder of Citizen Participation"—ranging from manipulation to token consulting, to complete citizen control. In the Fall/Winter issue of
Oregon Humanities magazine, writer Eric Gold describes "an artistic tradition called '
social practice,' which refers to works of art in which the artist, audience, and their interactions with one another are the medium. While a painter uses pigment and canvas, and a sculptor wood or metal, the social practice artist often creates a scenario in which the audience is invited to participate. Although the results may be documented with photography, video, or otherwise, the artwork is really the interactions that emerge from the audience's engagement with the artist and the situation." Participatory or interactive art creates a dynamic collaboration between the artist, the audience and their environment. Participatory art invites the audience to participate in the co-creation of art, rather than observing it quietly from a distance. The forms this can take are widely varied. Viewers may potentially touch, smell, write on, talk to, dance with, or play with the artwork in question. ==Distinctions between other forms of artistic participation ==
