Spontaneous Broadway is an advanced long-form improvised performance, usually based on audience suggestions. The audience typically submits titles of songs that have never been written, and the performers choose suggestions to create songs, the audience votes through acclamation on their favourite song, which is then used as the core of a brand new Broadway musical. The format received a favorable review from The New York Times when it premiered in New York in 1995. Though not required or necessarily encouraged by improv professionals, elements of humor inevitably surface in the performance because of the surprising and playful nature of improvisation and its use of typical Broadway stereotypes. The performers' songs are supported by an onstage musician or band that improvises the music, generally in the style of typical show tunes.
