Beethoven's so-called First Piano Concerto in C major was actually not his first: the one known as the 'Second Concerto', op. 19 in B-flat major, was written much earlier. However, he spent so much time elaborating the B-flat major Concerto that the C-major Concerto preceded it into print, and is thus called his 'First'. But even the First was revised several times. Beethoven probably performed it for the first time at the Hofburgtheater during an academy of the Tonkünstler Society on 29 March 1795.
