 The choral program includes two all-female choirs known as Treble Choir and Women's Chorale, a mixed four-part choir called ChoralWorks, and an all-male choir known as Men's Chorus. Membership in ChoralWorks and Women's Chorale is determined by audition. The choirs generally have three concerts during the school year, with additional performances in and outside of school at various times of the year. There are also three additional extracurricular ensembles, two all-female ensembles — Junior Varsity Women and Varsity Women — and one four-part mixed ensemble called ACEs (Advanced Choral Ensemble), all of which are determined by audition at the beginning of each school year. Every May, the choirs, along with the Jazz Band, stage a pops concert that features music from a variety of time periods and genres and also includes choreography and additional solo and small group performances. The concert has been held every year since 1970. Since 2013, a madrigal dinner in the style of a Medieval or Renaissance boar's head festival, is held in early December. Members of ChoralWorks and Women's Chorale wear period costumes and sing period repertoire while guests are served a three-course meal.
