Girardi created the roles of Blasoni in Johann Strauss's "Cagliostro in Wien" (1875), Andredl in Karl Millöcker's "" (1878), Jan Janicki in Millöcker's "Der Bettelstudent" (1882), Benozzo in Millöcker's "Gasparone" (1884), Kálmán Zsupán in Strauss's "The Gypsy Baron" (1885), Adam in Carl Zeller's "Der Vogelhändler" (1891), the title role in Edmund Eysler's "Bruder Straubinger" (1903), and Pali Rácz in Emmerich Kálmán’s "Der Zigeunerprimas" (1912). He contributed greatly to the Golden Age of Vienna operetta.
