It's not every day you can listen to the 23 bells, that make up a carillon, chime in the fresh Colorado air. Watch South High School choir perform with the University of Denver’s own carillonneur, Carol Jickling Lens. A screen will be put up to display the singers. Relax in the Ritchie Center courtyard as they sing holiday classics like, “Carol of the Bells.” Sun 3 p.m.
