[Footnote 28: Treitschke gives many particulars of the composition and first performance of the "Zauberflöte" (Orpheus, Mus. Taschenb., 1841, p. 242) in the Illustr. Familienbuch des österr. Lloyd (1852, II., p. xig), and in the Monatsschrift fur Theater und Musik (September 1857, p. 444); valuable old traditions are paixed with demonstrable falsehoods.] [Footnote 29: Allg. Wiener Mus. Ztg., 1841, p. 128.] [Footnote 30: C. F. Becker, N. Ztschr. fur Mus., XII., p. 112.] [Footnote 31: Da Ponte, Mem., I., 2, p. 124.] [Footnote 32: The story of the Requiem is familiar in all its details, and has been deprived of every trace of mystery or uncertainty. Niemetschek's simple account (p. 40), and Rochlitz's more highly coloured one (A. M. Z., I., pp. 149, 177), are both founded on statements by Frau Mozart. Full light has been thrown on the other side by the communications of the musicians J. Zawrzel (André, Vorber. zu Mozarts Requiem, Cäcilia, VI., p. 212), Krüchten (Cäcilia, VI., p. 217), Herzog (Köchel, Recensionen, 1854, No. 48, p. 753), who were all acquainted with Count Walsegg, and are trustworthy on the whole, although they differ from each other in matters of detail. Some facts, which it was thought unadvisable to publish, were vouched for to me in Vienna by A. Schmid and Al. Fuchs.] [Footnote 33: Niemetschek (p. 52) saw a short note from the Unknown, in which Mozart is urged to send the Requiem, and to name a sum for which he would undertake to supply annually a certain number of quartets.] [Footnote 34: The entry in the Autograph Catalogue is as follows: "September 5 (performed in Prague, September 6), La Clemenza di Tito, opera seria in due atti, per I' incoronazione di sua Maestà l' imperatore Leopoldo II., ridotta a vera opera dal Sgre Mazzoli, poeta di sua A. S. l' Elettore di Sassonia--24 pezzi." (In the printed score there are twenty-six pieces, not counting the overture; but the obbligato recitatives are counted separately here, and not in the original score.)] [Footnote 35: Seyfried, Càcilia, IV., p. 295.] [Footnote 36: Nothing is omitted but the duettino (3) (which, however, is included in "A Revised Copy of Mozart's Original," by Abbe Stadler) and the accompanied recitative (25).] [Footnote 37: The first three scenes were by P. Travaglia, in the service of Prince Ester-hazy, the fourth was by Preising of Coblenz, and the costumes were by Chérubin Babbini of Mantua.] [Footnote 38: J. Debrois, Urkunde uber die Krönung Sr. Maj. des Königs von Bohmen, Leopolds II., p. no.] [Footnote 39: Musik. Wochenbl., pp. 70, 94.]
