This Urtext edition by Henrik Wiese, Munich master flautist and Mozart expert, is enriched by an exciting foreword and an exhaustive critical apparatus. One reads there for example some peculiarities in the reception of the four quartets for flutes by Mozart: one of the quartets is very probably a forgery, and is therefore not by Mozart (C major, Anh. 171 [K. 285b]) - another has only two movements and, moreover, bizarre reception, which at least legitimates some suspicions as to the authenticity of the known version (G major, K. 285a) - a third, certainly an authentic quartet for Mozart flutes, has so far been badly dated following the Köchel catalog (A major K. 298, year of composition 1786 - and not 1778!). Only the first quartet for flutes, in D major (K. 285) is linked with certainty to Mozart's stay in Mannheim in 1777. It is there, as we know, that he fell in love with Aloysia Weber , Constanze's older sister, whom he married much later. The acquisition of this masterful edition is essential - if only for this work.
