To this the English editor feels in duty bound to say that Nottebohm’s argument seems to him at all points invulnerable. The autograph of the overture is no longer in existence. The score bought by Haslinger and the parts are copies which Beethoven corrected. On the first violin part the copyist had written “Ouvertura”; Beethoven added “in C, Characteristic Overture.” Under this title the composition was announced by Haslinger in 1828. He did not publish it at the time, but there were many references to it at its performance at Romberg’s concert and at other times as a “Characteristic” overture which had been found among Beethoven’s posthumous papers. Between 1828 and 1832, when Haslinger finally gave the work to the public, somebody made the discovery, which ought to have been made at sight of the manuscript, certainly at the first performance in 1828 (the melody of ~Florestan’s~ song occurring in it as one of the themes), that there was a connection between it and “Fidelio.” When Haslinger published it, therefore, he abandoned the title under which he had announced it four years before, and called it: “Overture in C, composed in the year 1805 for the opera ‘Leonore,’ etc.” Every student knows how valuable Nottebohm’s studies of the sketches are in the determination of dates. Composers usually write the overtures to their operas last; indeed, they must do so when utilizing thematic material drawn from the vocal numbers. Mr. Thayer has already called attention to the fact that the vocal numbers were taken up in the order of their occurrence, as Beethoven’s sketches show. They also show that the overture was sketched after all the vocal numbers had been planned. And the overture thus sketched was that known as No. 2. There is no hint of the overture No. 1 in the sketches made in 1804 and the beginning of 1805. Schindler says that Haslinger bought the overture immediately after it had been laid aside by Beethoven. That would have been in 1805. But Haslinger was not in Vienna till 1810. If Steiner and Co., with which firm Haslinger associated himself shortly after his arrival in the Austrian capital and of which the firm of Tobias Haslinger was the successor, was meant by Schindler, it remains a mystery that the publishers, so intimately connected with Beethoven, should have kept an overture under lock and key for 23 years and then have given it out as a work bought at the sale of Beethoven’s effects. That circumstance could only awaken the suspicion that the composer did not think it worthy of his name and fame. If he did so think, he would not have demanded that Haslinger publish it in 1823. Judging by internal evidence the overture certainly seems to be an earlier work than the overtures which the world knows by the titles “Leonore,” Nos. 2 and 3; but contemporary reports (a letter from Vienna printed in the “Journal des Luxus und der Moden,” Weimar, 1808) offer evidence in addition to the testimony of Seyfried that Beethoven did
