The Three Early Piano Sonatas, WoO 47, "Kurfürstensonaten" were composed by Ludwig van Beethoven in 1782 and 1783, when he was twelve and thirteen years old. Though lacking a distinct musical identity, the sonatas show a certain level of precocity and serve as a precursor to the masterworks he later produced. They are dedicated to the Elector (Kurfürst) Maximilian Frederick.
Like Mozart, Beethoven's music talents were recognized at a young age, and it is in these three sonatas that we are given an early glimpse of the composer's abilities, as well as his boldness. Even at his young age, Beethoven was writing in a form usually attempted by older, more mature composers, as the sonata was a cornerstone of Classical piano literature.
