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 as part 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 the repeated corrections. Unlike earlier publications, our edition contains the definitive version as in Mozart's manuscript. The piano reduction of our edition was undertaken by the celebrated pianist András Schiff, 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. / Piano

The New Robert Schumann Edition (RSA) is intended as a historico-critical edition of the collected works. They will be carefully studied and prepared according to present-day musicological and editorial techniques and presented in their entirety. Drafts, sketches and fragments, in short, everything that has come down to us as being authentically by Schumann and which, in most cases, has been deliberately preserved by him, will be brought together, evaluated as to its importance and documented in some form or other in the edition of the complete works.It is the aim of the edition to reproduce authentic texts which - having corrected scribal, copying and printing errors and eradicated later additions and other textual corruptions - will approach as closely as is possible the intention of the originals.The critical edition will form the basis of accurate performance material for Robert Schumann's work. / 2 Pianos 4 Mains
