Ludwig van Beethoven's Piano Concerto No. 1 in C major, op. 15, was written during 1796 and 1797. The first performance was in Prague in 1798, with Beethoven himself playing the piano.
Although described as his first piano concerto, this piece was Beethoven's third attempt at the genre, following an unpublished piano concerto in E-flat major (not to be mistaken for the "Emperor" concerto, Piano Concerto No. 5) and the Piano Concerto No. 2, published after Piano Concerto No. 1 (in 1801) but composed almost ten years earlier.
