The “Choralschola der Wiener Hofburgkapelle” exclusively consists of former members of the “Wiener Sängerknaben”. Since 1952 the ensemble has been singing the Gregorian chants at the Sunday services in the Wiener Hofburgkapelle. Due to this continuous work, the the Schola developed into an internationally acclaimed vocal ensemble. In search of adequate contemporary interpretation, the ensemble also relies on the scientific results of the musicological and historical research concerning the tradition of Gregorian music. Since 2002 the Schola, being complemented by boy singers, has been collaborating with René Clemencic to also concentrate on the music from the founding era of the “Hofkapelle” of emperor Maximilian in the late 15th century (Josquin, Isaak, a.o.).
