?Mozart's late E flat major Symphony was written in 1788, presumably for subscription concerts that ultimately did not take place. The new edition is based on the sole extant authentic source, the autograph from the Biblioteka Jagiellónska in Krakow. Unfortunately, the manuscript was notated negligently and faultily, which forced the editor to make frequent decisions about whether Mozart did or did not intend different articulations at many passages. Cliff Eisen's editorial competence was a major asset here.
