The Frossards were specialists in the art form "danse de caractére et pantomime". During the 1774-75 season, they made a success as members of the Sami people in the opera Birger Jarl written by the king himself. Their status as elite stars is exemplified by their salaries: in 1774, the Frossards were given a salary of 25.000 $. This compared to the salary of the opera singer Lovisa Augusti who, though a star at the Royal Swedish Opera, only had $6000.
