The Briar Chorus — made up of the Rose Choir (tenor/bass) and Thorn Choir (soprano/alto) — offer a high-level ensemble experience with a unique focus on individual vocal development. PSU’s largest concert choir rehearses twice weekly and performs frequently at community sings and concerts throughout the academic year.

While they maintain their distinct identities, Rose and Thorn are true counterparts. They rehearse in tandem and frequently join forces to perform a rich, diverse repertoire that utilizes the full spectrum of choral color.

The Briar Chorus offers a unique environment specifically designed for voice students who are serious about their individual craft.

Auditions are required and open to all students regardless of major.
