Cantus is an eight-member male vocal a cappella ensemble based in Minneapolis, Minnesota, USA. 　　Cantus is a full-time, professional vocal chamber ensemble, made up of eight men singing in a TTBB (tenor, tenor, baritone, bass), changed male voice arrangement. The artists are self-led, with programming and musical direction coming from within the group itself. The ensemble is known for innovative concert programming, often tying together works of numerous genres to explore a selected narrative, including classical music, orchestral-vocal repertoire, folk music, art song, popular songs, spirituals, and newly commissioned works. 　　The vocal group maintains a schedule of around 70 live concert performances and 30-40 education/outreach activities in a given season, both in the United States of America and abroad. Cantus is an active proponent of music education, encouraging people of all ages - especially men - to sing. The ensemble has worked with tens of thousands of singers throughout the country in educational activities ranging from master classes to festivals and collaborations. New members are acquired through annual national auditions. 　　The ensemble began as a student-run organization at St. Olaf College in 1995. After a successful northeast tour in the summer of 1998, Cantus transitioned into a professional ensemble and non-profit organization by 1999, based out of Minneapolis, MN.
