Beethoven's musical style
The compositions that Beethoven wrote in his formative period can be generally characterized by the composer's efforts to master the predominant classical language of the period. His works from this period can be subdivided into two, based on the composer's residence. First, various juvenalia, written when the adolescent Beethoven was in residence in Bonn and heavily indebted to the works of contemporaries, especially Mozart and his teacher, Christian Gottlob Neefe. These early efforts can be seen in a set of three piano sonatas and piano quartets (WoO 36) that Beethoven wrote before 1792. The Quartets, for instance, are each specifically modelled after three Violin sonatas Mozart published in 1781 – K 296, 379 and 380 – and Beethoven would later draw upon this familiarity in the composition of several of his own Violin Sonatas.
String Trios, Op. 9 (Beethoven)
The three String Trios, Op. 9 were composed by Ludwig van Beethoven in 1797–98. He published them in Vienna in 1799, with a dedication to his patron Count Johann Georg von Browne (1767–1827). They were first performed by the violinist Ignaz Schuppanzigh with two colleagues from his string quartet. According to the violinist and conductor Angus Watson, these were probably Franz Weiss on viola and either Nikolaus Kraft or his father Anton on cello. Each of the trios consists of four movements:Although this opus does not contain the most played works by Beethoven it was a significant milestone in his development as a composer. At the time of publication the 28-year-old Beethoven regarded the trios as his best compositions. The trios can be seen as a part of the preparation for the upcoming string quartets, which became the leading genre among his chamber music. The musicologist Gerald Abraham has remarked that in terms of their style and aesthetic value the string trios of Op. 9 rank with Beethoven's first string quartets which ousted the trios from the concert halls. Beethoven composed no further trios after the first quartets (Op. 18) were published in 1801. Each trio is of four movements with sonata form in the first movements, suggesting that Beethoven did not intend them to be light chamber pieces.
