Vocal Music

The Hill School Chorus and Chamber Choir meet during the academic day, giving students the opportunity to perform consistently throughout the week. Each program is designed to allow students with the skill, desire, and commitment to become excellent singers.

It also provides those students with more experience and skills an environment where they can get instruction in music reading and vocal technique, while experiencing a variety of literature, which will include lighter and contemporary repertoire. The courses may be taken as a graded or non-graded courses. Students interested in participating in the vocal program must request the desired course on their schedule in the summer, rather than fall, to avoid scheduling conflicts.

Versatile students can be involved in multiple performing vocal ensembles and it is not uncommon to be in both instrumental and vocal groups. Musicians are given the opportunity to receive a graded credit for their participation within a vocal ensemble by electing to perform before a jury each list.

Talented Hill vocalists have the opportunity to audition for various choral festivals throughout the academic year.

Courses Offered:

  • Chorus (term course, graded or non-graded)
  • Chamber Choir (Advanced Audition Choir; year-long, graded or non-graded)
  • The Hilltones & The Hilltrebles (Auditioned a cappella ensembles)
