Körslaget (The Battle of Choirs) is a Swedish entertainment TV program on TV4.
The format was developed by Friday TV and based on an idea from Caroline af Ugglas,[1] Heinz Liljedahl and Patrik Hambraeus.
A US version, Clash of the Choirs, was broadcast on NBC in December 2007.
In each season of Körslaget, seven known musicians from Sweden start their own choirs with 20 members in each.
The winning team receives a certain amount of prize money to be donated to something in the city that the choir in question came from.
