Permanent sound installation at Ejer Bavnehøj


The iconic tower at Ejer Bavnehøj near Skanderborg, Denmark has been transformed into a permanent site-specific sound installation that can be heard at random times during the day. Visitors standing under the tower arches are surrounded by sound for a few minutes. The site traces back to the days of the Vikings, when signal hills with bonfires were used to send messages about approaching enemies.

Signal is an unending hymn commissioned by The Friends of Ejer Bavnehøj to celebrate the centennial of the reunification of Northern Schleswig with Denmark in 1920. A specially designed permanent 4-channel speaker system is built into the tower walls. The music is generated by software that uses algorithmic (rule based) composition technics to continually generated and transform new music. The installation is active for about 3-5 minutes at a time with pauses of 30-60 minutes in between. There is no time schedule, so visitors cannot know if or when they will hear the music. Signal began playing on June 15, 2020.
