Although the composer did not succeed in bringing his new Symphony and Concerto to public performance this year, an opportunity offered itself for him to give the general public as fine a taste of his quality as composer for the violin, as he had just given to the frequenters of Rasoumowsky’s quartet parties in the Op. 59, namely, Op. 61, the work superscribed by its author: ~Concerto par Clemenza pour Clement, primo Violino e Direttore al Theatro a Vienne, dal L. v. Bthvn., 1806~;--or, as it stands on Franz Clement’s concert programme of December 23 in the Theater-an-der-Wien: “2. A new Violin Concerto by Hrn. Ludwig van Beethoven, played by Hrn. Clement.” It was preceded by an overture by Méhul, and followed by selections from Mozart, Cherubini and Handel, closing with a fantasia by the concert-giver. When Dr. Bertolini told Jahn that “Beethoven as a rule never finished commissioned works until the last minute,” he named this Concerto as an instance in point; and another contemporary notes that Clement played the solo ~a vista~, without previous rehearsal. The list of publications this year is short: ~LI^{me} Sonata pour le Pianoforte~, F major, advertised April 9 in the “Wiener Zeitung” by the Kunst- und Industrie-Comptoir. There is no tradition that Beethoven ever explained why he called this his ~fifty-first~, or the F minor his ~fifty-fourth~ Sonata. The best that Czerny could suggest is that “perhaps he sketched that number in manuscript and then destroyed them or used them in another form.” Others have made lists of all the works in sonata-form, including the symphonies; but none has been so probably right as to produce conviction. ~Grand Trio pour deux Hautbois et un Cor Anglais~, C major, advertised by Artaria and Co., April 12, without opus number. At a later date it was called Op. 87. The same work for two violins and viola, and as a sonata for pianoforte and violin, was advertised at the same time. “Andante” (Favori) in F major, for Pianoforte. This was originally the second movement of the Sonata, Op. 53--according to the anecdote before given from Ries’s “Notizen.” “Sinfonia eroica,” Op. 55, dedicated to Prince Lobkowitz, advertised by the Kunst- und Industrie-Comptoir on October 29. Besides these works, Johann Traeg advertised on June 18 “6 Grands Trios pour le Pianoforte, violon obligé et violoncello ad lib.,” Op. 60, Nos. 1 and 2. These are arrangements of the Quartets, Op. 18. Also “3 Grands Trios pour le Pianoforte, Violon et Violoncello,” Op. 61, No. 1; arrangements of the Trios, Op. 9. Before February, 1807, the other numbers of the two works had been completed and had left the press. The opus numbers were not recognized by Beethoven, for, as is seen above, 60 and 61 belong to original works of a very different order. FOOTNOTES: [34] Twice only.
