Students in 5th-8th grades have the opportunity to sing for the St. Theresa choir at school Masses. The choir rehearses one day each week, after school hours. Girls in 5th-8th grade may audition for One Voice. The One Voice Choir attends LMEA District IV Honor Choir and Festival, sings at Mass, and performs a Christmas and Spring concert. One Voice rehearses one day each week, after school hours.
Both choir programs build on musical skills gained each year in sight-reading music, harmony, and proper breathing techniques. Students are also given the opportunity to increase self-confidence through solo singing.
St. Theresa Middle Choir is an award-winning choir and has done an extraordinary job representing the school.
