Chorus Viennensis, a male voice choir consisting of former members of the Wiener Sängerknaben (Vienna Boys Choir), was created in 1952 by its director, Josef Schnitt. The repertoire of the adult choir covers works from many style periods. Though probably best known for its recordings of Schubert, it has also recorded works by Bach, Haydn, Mozart, Beethoven, Hindemith, Shostakovich, and Britten. As the choralschola of the Wiener Hofburg, members of the choir also specialize in the performance of Gregorian chant under the direction of Father Hubert Dopf. Former directors of Chorus Viennensis include Ferdinand Grossmann and Hans Gillesberger. From 1997 to 2001 the choir was directed by Raoul Gehringer. Gehringer was a Vienna boy chorister from 1981 to 1985, after which he attended the Vienna Conservatory, studying piano, clarinet, music pedagogy, and composition while singing with Chorus Viennensis. His choral conducting teachers were Herwig Reiter and Johannes Prinz.
