In 1495, he was a chaplain and cantor at the court in Vienna; he was also the canon and provost of the Diocese of Ljubljana.
In 1513 he was given the position of the Bishop of Vienna, although he continued to work as the main music organiser in the city and probably also himself composed.
[10] As a leader who fostered a bridge between faith and art, Slatkonia left a legacy in Vienna as well as in Slovenia.
The George Slatkonia Conservatory of Music (Konservatorij za glasbo Jurij Slatkonja), founded by the Diocese of Novo Mesto, is named after him.
