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's, Beethoven's musical talent was recognized at a young age, and these three sonatas give an early glimpse of the composer's abilities, as well as his boldness. Beethoven was writing in a form usually attempted by older, more mature composers, as the sonata was a cornerstone of Classical piano literature.
