happening

n. occasion; occurrence, event

v. occur, take place

In the late 1950s and early 1960s, a happening was a performance, event or situation meant to be considered as art. Happenings could take place anywhere, were often multi-disciplinary, often lacked a narrative and frequently sought to involve the audience in some way. Key elements of happenings were planned, but artists would sometimes retain room for improvisation.
