Consortium Classicum was a German chamber music ensemble founded in 1966 by clarinetist Dieter Klöcker. The group originated from the Detmolder Bläserkreis and evolved through the Rheinische Bläsersextett into its final form. Consortium Classicum consisted of soloists, music professors, and members of renowned orchestras, performing a varied repertoire that included both standard works and newly discovered pieces. Their concert activities spanned numerous festivals worldwide, including the Salzburg Festival, Vienna Festival Weeks, and Berlin Festival Weeks, as well as tours in the USA, South America, Japan, Russia, China, and Australia. Their discography includes notable albums such as Music From Rossini's Wilhelm Tell Arranged For Harmonie By Wenzel Sedlak (1988) and Joseph Haydn: Arrangements For Harmonie (1996). Consortium Classicum received several awards, including the German Record Award, Premio della Critica Discografica Italiana, and Wiener Flötenuhr. Their extensive music archive, compiled from decades of research, featured works by lesser-known composers of the 18th and 19th centuries. Consortium Classicum remained active until the 2010s.
