The Violin Sonata No. 9 of Ludwig van Beethoven, commonly known as the Kreutzer Sonata, was published as Beethoven’s Opus 47. It is known for its demanding violin part, unusual length (a typical performance lasts slightly less than 40 minutes), and emotional scope — while the first movement is predominantly furious, the second is meditative and the third joyous and exuberant.
The sonata was originally dedicated to the violinist George Bridgetower (1778–1860), who performed it with Beethoven at the premiere on 24 May 1803 at the Augarten Theatre at a concert that started at the unusually early hour of 8:00 am. Bridgetower sight-read the sonata; he had never seen the work before, and there had been no time for any rehearsal. However, research indicates that after the performance, while the two were drinking, Bridgetower insulted the morals of a woman whom Beethoven cherished. Enraged, Beethoven removed the dedication of the piece, dedicating it instead to Rodolphe Kreutzer, who was considered the finest violinist of the day. However, Kreutzer never performed it, considering it “outrageously unintelligible”. He did not particularly care for any of Beethoven’s music, and they only ever met once, briefly.
Sources suggest the work was originally titled “Sonata mulattica composta per il mulatto Brischdauer [Bridgetower], gran pazzo e compositore mulattico” (Mulatto Sonata composed for the mulatto Brischdauer, big wild mulatto composer), and in the composer’s 1803 sketchbook, as a “Sonata per il Pianoforte ed uno violino obligato in uno stile molto concertante come d’un concerto”.
