Singing voices are heard often at St. Andrew's, both in chapel services on Wednesdays and Sundays and in concert, throughout the year. Choral ensembles sing both formally and informally at School Meeting and at special concerts throughout the year and occasions such as Arts Weekend.

The Choral Scholar program, open to all students in all forms, is aimed at developing the complete choral singer. Students rehearse during the academic day, receive vocal and aural training and learn music theory and sight-singing in one of two ensembles, Chorale and Choral Scholars.

• Chorale frequently provides music for St. Andrew's Chapel services, performs major choral works, and participates in the Service of Nine Lessons and Carols in December and in the spring Arts Weekend concert schedule.
• Choral Scholars frequently provides music for St. Andrew's Chapel services as well as special events on campus and also has numerous singing engagements off campus throughout the year. Choral Scholars tours internationally, recently to Venice and Croatia, and records frequently.

While the groups generally rehearse separately, at many points in the year the two ensembles prepare music together. With improvement and advancement through the program, students can move from one ensemble to the other.

In addition to the Choral Scholars program, Noxontones is an acappella ensemble of roughly 14-16 singers. Noxontones rehearses twice weekly in the evenings and performs a number of times throughout the year.

Private voice lessons are also available as scheduling allows.
