Beethoven wrote five concertos for piano and orchestra. It doesn’t sound like much; his near-contemporary Mozart composed 27. But although it may be a bit smaller, Beethoven’s contribution is a true monument in the history of music. He used the first two concertos to move away from his example, Mozart (whose last piano concerto was from 1791, while Beethoven completed his first in 1795); in Concerto no. 3 Beethoven carved out new dimensions for the genre’s dramatic possibilities. And Concertos nos 4 and 5 have proved to be unmatched in their genre: the radiant Concerto no. 4 is worshipped by experts and aficionados alike, while no. 5 is the all-time favourite of the public at large. Almost 25 years passed between Beethoven’s first sketches for a piano concerto and the double line he drew under his last one. His piano concertos thus show a development covering more than half of the composer’s life.
