The Piano Concerto No. 2 in B-flat major, Op. 19, by Ludwig van Beethoven was composed primarily between 1787 and 1789, although it did not attain final form till 1798. It was used by the composer as a vehicle for his own performances as a young virtuoso, initially intended with the Bonn Hofkapelle. It was published in 1801, by which time he had also published the Piano Concerto No. 1 in C major, although it had been composed after this work.
The work is scored for solo piano, flute, two oboes, two bassoons, two horns and strings.
The B-flat major Piano Concerto became an important display piece for the young Beethoven as he sought to establish himself after moving from Bonn to Vienna. He was the soloist at its premiere on March 29, 1795, at Vienna's Burgtheater in a concert marking his public debut. (Prior to that, he had performed only in the private salons of the Viennese nobility.) While the work as a whole is very much in the concerto style of Mozart, there is a sense of drama and contrast that would be present in many of Beethoven's later works. Beethoven himself apparently did not rate this work particularly highly, remarking to the publisher Franz Anton Hoffmeister that it was "not one of my best".
