The Wartburg Choir is a select auditioned a cappella choir from Wartburg College in Waverly, Iowa. Founded in 1937, the choir became one of the first American college groups to tour Europe. The Wartburg Choir performs sacred music from all historical periods and styles and often premieres new works by contemporary composers. Called a "mighty fortress of skill" by The Washington Post, the Wartburg Choir is one of Wartburg's three musical ensembles that tour internationally on a triennial basis. Beyond national and international tours, the choir has received invitations for special appearances in the United States and abroad.
