A Narrenmarsch is a composition of march music that is exclusively played at Fastnacht.
The marches are mostly played during parades and other public events of the Narren.
Many of these marches also got lyrics written for them that participants and audience can sing along.
The Narrhallamarsch from Mainz from 1840 is regarded as the first specifically for the Fastnacht arranged march.
It was originally composed as "Marsch der Freiwilligen Jäger" for the German Campaign of 1813 between 1813 and 1815 but is still played at the Fasnet.
