The "Narrhallamarsch" is usually used as a march which is played whenever a speaker enters or leaves the stage on a convention. Narr in German means jester, and Narrhalla is the jesters' heaven, and a pun on Valhalla which was Odin's heaven in Northern mythology.
In 1838, the people of Mainz founded the Mainzer Carneval-Verein ("Carnival Club of Mainz") and were searching for a lead melody for the local carnival. One of the founding members was the Austrian bandmaster Karl Zulehner (1805–1847), who got inspired by the 1840 performance in Mainz of Adolphe Adam's opera Le brasseur de Preston (1838) (German: Der Brauer von Preston) and used some of its musical motives to create the "Mainzer Narrhallamarsch". The new tune was presented at the opening of the campaign in 1844 and became the signature tune of the Meenzer Fassenacht.
