The Harold

Harold is a structure used in longform improvisational theatre. Developed by Del Close and brought to fruit through Close's collaboration with Charna Halpern, the Harold has become the signature form of Chicago's iO Theater and the Upright Citizens Brigade Theatre in New York City and Los Angeles. It is now performed by improv troupes and teams across the world. The Committee, a San Francisco improv group, performed the first Harold in Concord, California, in 1967. They were invited to a high school and decided to do their improvisations on the war in Vietnam. On the way home in a Volkswagen bus, they were discussing the performance, when one of them asked what they should call it. Allaudin (Bill) Mathieu called out "Harold", which was a joking reference to a line from A Hard Day's Night where a reporter asks George Harrison what he calls his haircut and he answers "Arthur". Close later remarked that he wished he had chosen a better name.

When The Committee disbanded in 1972, improv company Improvisation, Inc. was the only company in America continuing to perform Close's "original" Harold: a 45-minute free-form piece that would seamlessly move from one "Harold technique" to another. In 1976, two former I-Inc performers, Michael Bossier and John Elk, formed Spaghetti Jam, performing in San Francisco's The Old Spaghetti Factory through 1983. Spaghetti Jam performed Harolds while also turning Spolin games and Harold techniques into stand-alone performance pieces (i.e., shortform improv).

Close and Halpern's 1994 book Truth in Comedy is the definitive text on the form. It describes a "training wheels Harold" as three acts (or "beats"), each with three scenes and a group segment. With each beat, the three scenes return. By the end of the piece, the three scenes have converged.
