The Armstrong Orchestra program has a rich history of excellence. With three orchestras, the program is able to meet the needs of each high school string student.
Freshman Orchestra meets fourth hour and is open to all ninth grade students. All ninth grade string students entering Armstrong high school participate in the Freshmen Orchestra their first year. The ensemble performs three major concerts per year: October, December and May along with the State Orchestra Festival in March.
Philharmonic Orchestra meets first hour & third hour, is open to 10th-12th grade students, and is a non-auditioned orchestra. Advanced string techniques (bowing techniques, vibrato, shifting, etc.) are a focus of this orchestra, which also performs two major concerts per year in December and May and at the Solo/Ensemble Festival in April.
Symphony Orchestra meets sixth hour and is the advanced-level orchestra at Armstrong High School. Symphony is open to 10th-12th grade students by audition the previous spring. Symphony performs various concerts throughout the year including the Fall Orchestra Hall concert in conjunction with the Cooper High School Symphony and each of the advanced choirs. The Symphony performs as part of the annual Northwest Suburban Music Festival, and members are selected into the All-Conference Orchestra. Members are highly encouraged to take private studio lessons on their instrument.
