The Concerto for Two Pianos and Orchestra in A♭ major was written by Felix Mendelssohn when he was 15 years old, and is dated 12 November 1824.
[1] Written for two pianos and a full orchestra, the work received its first public performance in Berlin, in 1825.
He performed it again on 20 February 1827 at Stettin, where the cathedral organist, composer, baritone singer and conductor Carl Loewe organised concerts.
It may have been inspired by the occasion when Mendelssohn met Ignaz Moscheles in Berlin in 1824, when Moscheles accepted an invitation to visit Abraham Mendelssohn Bartholdy to give some music lessons to his children Felix and Fanny.
The concerto was not played for many years until the manuscript was found in the archive of the Berlin State Library in 1950.
