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.

Beethoven's early years in Bonn arguably represent a further, preliminary, period. His earliest known composition was from 1782, and a total of 40 pieces by him dating from 1792 or earlier are known today (though mainly from much later sources). Today his best-known works from before 1790 are three piano quartets and three piano sonatas, the quartets being closely modelled on Mozart's sonatas for piano and violin. From 1790–1802, his best music can be found in a cantata and a number of concert arias, and in some variations for solo piano, while his instrumental music (including movements of symphonies and a violin concerto, as well as various fragmentary chamber works) is conservative and uninspired.
