The first of the season's Children's Hour concerts features dance music from different cultures plus a selection of light, entertaining songs. The Iceland Symphony's Children's Hour concerts have been extremely popular. The programming and length of the concerts are tailored to the needs of audiences too young for the full-length children's concerts in the Litli tónsprotinn series. Leaders of the Children's Hour concerts are concertmasters Sigrún Eðvaldsdóttir and Nicola Lolli, and Master of Ceremonies is the ISO's educational director, Hjördís Ástráðsdóttir. Children's Hour concerts are about 30 minutes long and are held in Hörpuhornið, the open space on the second floor of Harpa, just outside Eldborg hall.
