When Wagner visited the Vienna Court Opera to rehearse possible singers for this production, the management at Vienna suggested staging the opera there. Originally, the tenor Alois Ander was employed to sing the part of Tristan, but later proved incapable of learning the role. Parallel attempts to stage the opera in Dresden, Weimar and Prague failed. Despite over 70 rehearsals between 1862 and 1864, "Tristan und Isolde" was unable to be staged in Vienna, winning the opera a reputation as unperformable.
