“Only in this room” (the large Redoutensaal), says Schindler, “was the opportunity offered to put into execution the manifold intentions of the composer in the Battle Symphony. With the help of the long corridors and the rooms opposite to each other the opposing forces were enabled to approach each other and the desired illusion was strikingly achieved.” Schindler was among the listeners on this occasion and gives assurance that the enthusiasm awakened by the performance, “heightened by the patriotic feeling of those memorable days,” was overwhelming. Among the direct consequences of this sudden and boundless popularity of Beethoven’s music, to which Mälzel had given the occasion and impulse, was one all the more gratifying, because totally unexpected--the revival of “Fidelio.” “The Inspizienten of the R. I. Court Opera, Saal, Vogel and Weinmüller, about this time were granted a performance for their benefit, the choice of a work being left to them, without cost.” There was then no opera, German, French or Italian, likely to draw a remunerative house in the repertory of the theatre, which could be produced without expense to the institution. The sensation caused by Beethoven’s new music, including the numbers from “The Ruins of Athens” in which Weinmüller had just sung, suggested “Fidelio.” All three had been in Vienna at its production and therefore knew it sufficiently to judge of its fitness for them as singers, and the probability of its now being successful; at all events the name of Beethoven would surely secure for their night a numerous audience. “Beethoven was approached for the loan of the opera,” says Treitschke, who had this year been re-appointed stage-manager and poet at the Kärnthnerthor-Theater after having been employed some years at the Theater-an-der-Wien, “and very unselfishly declared his willingness, but on the unequivocal condition that many changes be made.” At the same time he proposed my humble self as the person to make these changes. I had enjoyed his more intimate friendship for some time, and my twofold position as stage-manager and opera-poet made his wish a pious duty. With Sonnleithner’s permission I first took up the dialogue, wrote it almost wholly anew, succinct and clear as possible--an essential thing in the case of ~Singspiele~.
