The Carterville High School Concert Jazz Ensemble is the extra-curricular performing ensemble at CHS. Students who wish to participate in CJE must go through a tryout in October at the conclusion of marching season. Those students who make it through the audition process rehearse twice a week after school, on Mondays and Wednesdays. The CHS Concert Jazz Ensemble performs community concerts each winter and spring, participates in local area jazz festivals, and participates in IHSA Organizational Contest. Students are exposed to large ensemble literature as well as solo and improvisation study. The CHS Concert Jazz Ensemble also performs alongside Symphonic Winds during the spring, including performing on the recruiting tour of CUSD 5 elementary schools. Rehearsals are required every Monday and Wednesday, after school, 3:30-4:15 PM.
