Beethoven's abandonment (if there really was one) of the rooms in the theatre in the spring of 1804, and his subsequent relinquishment of the apartments in "das Rothe Haus" to share those of Breuning, compelled his brother Kaspar to seek a lodging of his own, which he found for the present on the Hohen Markt. But the new contract, with Baron Braun, gave the composer again a right to the apartments in the theatre building, which he improved, at the same time retaining the dwelling in the Pasqualati house. The city directory for 1805 gives his address at the theatre, and there he received visitors; at the Pasqualati house he was accustomed to seclude himself for work, forbidding his servant to admit any person whatever. In the summer he retired to Hetzendorf, and wrought out his opera, sitting in the same crotched oak in the Schönbrunn Garden where, four years before, he had composed the "Christus am Ölberg." Thus again he had three lodgings at the same time, as in the preceding summer; with this difference, that now one was no expense to him. The thousand times repeated story of Ries, that in 1804 he had ~four~ dwellings at once, is a mistake.
Before his migration to Hetzendorf--say about the middle of June--Beethoven had completely sketched the music of his opera. This is made sufficiently certain by one of those whimsical remarks that he was in the habit of making on the blank spaces of whatever manuscript he happened to have before him. In this case he writes: "June 2d Finale always simpler. All pianoforte music also. God knows why my pianoforte music always makes the worst impression, especially when it is badly played." This is in the midst of sketches to the final chorus of the opera, and is written upon the upper outer corner of page 291 of the "Leonore" sketchbook which became the property of Mr. Paul Mendelssohn, of Berlin. The principal value of this manuscript lies of course in the insight which it gives the musician into the master's methods of composition;[30] but for the biographer the volume is by no means without its value. Its striking confirmation of the previously formed opinion, that two current notions in relation to the composition of the opera are erroneous, well repays the toil of studying it through. First: A misinterpreted sentence in Jahn's article on "Leonore, oder Fidelio," has originated and given currency to the idea that Beethoven's "daring enthusiasm for the welfare of men and their rights" led him to begin his sketches for the opera with the "second finale, with its hymn-like character." But the sketchbook, if it proves anything, proves this: that Beethoven began at the beginning and took up all the principal numbers in order, as they stood in Sonnleithner's text; that the final choruses were the last to be sketched; and that this sketchbook happens to begin in the midst of the chorus of prisoners (originally the second finale) because the previous studies are wanting.
