The Wiener Sängerrunde is a mixed four-part choir with around 50 active singers. Founded in 1978 by Karl-Hans Straßl (a student of Prof. Leo Lehner), the choir was led by him until 2000, when his son Karl-Gerhard Straßl took over as principal choirmaster, with Karl-Hans Straßl as deputy. The choir’s repertoire ranges from sacred works, Viennese music, Austrian and international folk songs to contemporary music. The Wiener Sängerrunde has already performed at more than 1,000 events and has completed in excess of 20 tours, travelling to many European countries as well as Israel, South Africa and China.
