NOTUS, the Contemporary Vocal Ensemble at the Indiana University Jacobs School of Music, is the only university-based vocal group in the United States exclusively dedicated to the study and performance of vocal and choral repertoire written after 1900. It includes singers, composers, young scholars and instrumentalists chosen for their special interest in the music of our time. Depending on the repertoire, the ensemble adjusts its size to perform solo vocal, chamber choral and large oratorio-like compositions. After its founding in 1980 by Alan Harler, the ensemble was directed by Indiana University Professor Emeritus Jan Harrington until 1992 and by Carmen Helena Téllez from 1992-2012. It is conducted by Dominick DiOrio, who renamed the group NOTUS in 2013.
