Music is an essential part of the Mass. Saint Peter has choirs for all ages:

• Adult Choir: Members practice together then sing during Saturday evening and Sunday morning Masses.
• Youth Choir: Youth grades 7-12 sing slightly more contemporary worship music at the Sunday night Mass.
• Senior Believers Choir: Children grades 3 through 6 lead the music at designated Masses during the school year.
• Young Believers Choir:  Children of ages 5 through grade 2 perform at several Masses during the school year.
