that he did not mean that they could not applaud. After the performance Wagner complained, "Now I don't know. Did the audience like it or not?" At subsequent performances some believed that Wagner had wanted no applause until the very end, and there was silence after the first two acts. Eventually it became a Bayreuth tradition that no applause would be heard after the first act, but this was certainly not Wagner's idea. In fact, during the first Bayreuth performances, Wagner himself cried "Bravo!" as the Flowermaidens made their exit in the second act, only to be hissed by other members of the audience. At some theatres other than Bayreuth, applause and curtain calls are normal practice after every act. Program notes until 2013 at the Metropolitan Opera in New York asked the audience not to applaud after Act 1. Post-war performances Parsifal is one of the Wagner operas regularly presented at the Bayreuth Festival to this day. Among the more significant post-war productions was that directed in 1951 by Wieland Wagner, the composer's grandson. At the first Bayreuth Festival after World War II he presented a radical move away from literal representation of the Hall of the Grail or the Flowermaiden's bower. Instead, lighting effects and the bare minimum of scenery were used to complement Wagner's music. This production was heavily influenced by the ideas of the Swiss stage designer Adolphe Appia. The reaction to this production was extreme: Ernest Newman, Richard Wagner's biographer described it as "not only the best Parsifal I have ever seen and heard, but one of the three or four most moving spiritual experiences of my life". Others were appalled that Wagner's stage directions were being flouted. The conductor of the 1951 production, Hans Knappertsbusch, on being asked how he could conduct such a disgraceful travesty, declared that right up until the dress rehearsal he imagined that the stage decorations were still to come. Knappertsbusch was particularly upset by the omission of the dove that appears over Parsifal's head at the end of the opera, which he claimed inspired him to give better performances. To placate his conductor Wieland arranged to reinstate the dove, which descended on a string. What Knappertsbusch did not realise was that Wieland had made the length of the string long enough for the conductor to see the dove, but not for the audience. Wieland continued to modify and refine
