Nordic Music Days is the oldest ongoing collaboration among the Nordic countries: a festival for new Nordic music that was founded in 1888 and had its origins in existing musical collaboration. It is one of the oldest and best respected festivals for contemporary classical music in the world. The festival is unique in the respect that it is arranged by the composers themselves. Each year one of members, the national societies of composers, arranges the festival on behalf of the Council of Nordic Composers.
