Mozart - Horn Concerto No 3 in Eb major, K. 447

Wolfgang Amadeus Mozart's Horn Concerto No. 3 in E♭ major, K. 447, was completed between 1784 and 1787 in Vienna. The composition was written as a friendly gesture for the hornist Joseph Leutgeb (his name is mentioned a few times in the score), and Mozart probably did not consider it as particularly important, since he failed to enter it to the autograph catalogue of his works. The autograph score remains well preserved; it is stored in the British Library in London. The Romance is given an individual header in the autograph, suggesting that it was the first movement to be composed and Mozart later expanded the work into a full concerto by adding the outer movements. This theory is supported by the fact that the foliation numbers on the autograph restart at the slow movement.
