In Hljóðhimnar you can conduct the Iceland Symphony Orchestra, snuggle up to the lullabies and songs of the Icelandic Opera, look through the mouseholes of Maximus Musicus, sail around oceans of music with the Reykjavik Big Band and so much more. Hljóðhimnar is a place for children and their families to discover the magical world of sound and music. It is the heart of children's culture in Harpa.
