The Quartet Program, in its 44th anniversary year, and in collaboration with the University of Colorado College of Music, is an intensive, four-week, summer chamber music program which brings together some of the most highly gifted young performers from around the world and forms them into eight quartets. Most American professional chamber music groups and orchestras today boast one or more QP alumnus. Each quartet rehearses six hours per day and receives coaching from world-famous faculty.
