The Choral Union is Robert Morris University?s largest choral ensemble, open to students, faculty, staff, alumni, and community members. The Choral Union performs 2-3 concerts per year, including a choral masterwork in the Spring semester. While singers from a wide variety of backgrounds will find their home in the Choral Union, requirements for membership include a certain degree of musical and vocal ability, as well as a commitment to regular attendance, and a love for choral singing.
