Junior Orchestra

July 9 – July 15, 2023

Designed for junior high string students, the primary focus of this program is developing individual musicianship through a large ensemble setting. Students will audition and be placed in either the Junior Orchestra or Junior Strings. Classes include full ensemble and sectional rehearsals, masterclasses, and elective courses. Wind and percussion students must sign up for Junior Band, and placement into Junior Orchestra will be based on audition during the first day of camp. Wind and percussion students that place highest in auditions and indicate interest will be selected to perform exclusively in the Junior Orchestra during their camp experience.
