A companion-piece to this movement is the fragment of a Concerto for Violin in C major, of which the autograph is in the archives of the Gesellschaft der Musikfreunde in Vienna, the handwriting of which indicates that it belongs to the early Vienna if not the Bonn period. That it is a first transcription is indicated by the fact that there are many erasures and corrections. The fragment contains 259 measures, embracing the orchestral introduction, the first solo passage, the second _tutti_ and the beginning of the free fantasia for the solo instrument; it ends with the introduction of a new transition _motif_ which leads to the conjecture that the movement was finished and that the missing portion has been lost.[54] A Trio in E-flat for Pianoforte, Violin and Violoncello, found among Beethoven’s posthumous papers, was published in 1836 by Dunst in Frankfort-on-the-Main. On the original publication its authenticity was certified to by Diabelli, Czerny and Ferdinand Ries, and it was stated that the original manuscript was in the possession of Schindler; Wegeler verified the handwriting as that of Beethoven. Schindler cites Beethoven’s utterance that he had written the work at the age of 15 years and described it as one of his “highest strivings in the free style of composition,” which was either a misunderstanding of Schindler’s or a bit of irony on the part of Beethoven. Nearer the truth, at any rate, is a remark in Gräffer’s written catalogue of Beethoven’s works: “Composed _anno_ 1791, and originally intended for the three trios, Op. 1, but omitted as too weak by Beethoven.” Whether or not this observation rests on an authentic source is not stated.[55] Whether or not the Pianoforte Trios, Op. 1, were composed in Bonn may be left without discussion here, since we shall be obliged to recur to the subject later. The facts about them that have been determined beyond controversy are, that they were published in 1795; were not ready in their final shape in 1794; and were already played in the presence of Haydn in 1793. OTHER WORKS COMPOSED IN BONN The Variations in E-flat for Pianoforte, Violin and Violoncello, which were published in 1804 by Hofmeister in Leipsic as Op. 44, apparently belong to the last year of Beethoven’s life in Bonn. Nottebohm found a sketch of the work alongside one of the song “Feuerfarbe,” which fact points to the year 1792; Beethoven in a letter to the publisher appears not to have laid particular store by it, a circumstance easily understood in view of the great works which had followed the youthful effort.
