The Lehigh University Choral Union, composed of students, faculty, staff, and Lehigh Valley community members is the Lehigh Valley’s only symphonic choir. Performing three times a year with internationally known soloists and full symphony orchestra, the 150 singers of the Choral Union bring major works of the choral-orchestral repertoire to a broad audience. Recent repertoire includes Bach’s St. Matthew Passion and Beethoven’s Missa Solemnis.
