The Sacred Heart Orchestra is open to students in grades 5-12 who play string, woodwind, brass and percussion instruments. Rehearsals are held every Thursday from 3:45 - 5:30 p.m. and every Monday at lunchtime in the Duchesne Room. Regular performances include the Christmas Concert, Family Festival, Spring Concert and the Grade 12 Graduation Ceremony.
The orchestra performs music from the Western classical and popular traditions as well as arrangements of music from around the world. Rehearsals involve scales and chorale warm-ups, full-orchestra rehearsal of concert pieces and smaller sectional work where necessary. Auditions are held at the beginning of the school year to determine part assignments and seating arrangement. Most orchestra members take weekly private lessons and many take advantage of extra performance opportunities, such as the Instrumental Solo & Ensemble Festival and the prestigious Kanto Plain Honor Band and Orchestra Festival (both held in early March).
