Piano reduction-According to Mozart s own catalogue K. 491 was completed on 24 March 1786 it was Mozart s only Piano concerto aside from K. 466 that was in a minor key. It was probably first performed two weeks later aspart of an academy at the Burgtheater in Vienna. Mozart was extremely pressed for time while composing this work a fact that is shown both by the cursory way in which the autograph was written and by therepeated corrections. Unlike earlier publications this edition contains the definitive version as in Mozart s manuscript. The Piano reduction of this edition was undertaken by the celebrated pianist AndrásSchiff to whom we also already owe our reductions of the concertos K. 453 467 488 and 503 (HN 765 766 767 and 825). He also supplied the fingerings for the solo part the cadenzas and the lead-ins.
