The Grant Park Music Festival is the nation’s only free, outdoor classical music series of its kind. Each summer, the Festival presents ten weeks of free classical concerts to all of Chicago at the Jay Pritzker Pavilion in Millennium Park. Audiences can watch as the Grant Park Orchestra and Chorus and guest artists rehearse upcoming performances. Rehearsals take place Tuesday-Friday afternoons all Season long. During breaks in rehearsals, Festival docents lead informal talks about the music, composers, and the history of classical music. For a full schedule, see the Festival website.
