Details: The present edition contains the complete productions released by cpo between 1993 and 2018 on the subject of Michael Haydn's symphonies and wind concertos. During the course of a quarter of a century, as might well be imagined, a wealth of material accumulated that could not be put to renewed use without considerable cuts. Nine authors had contributed information about the sources and special qualities of the music to the original releases, which necessarily led to duplications, repetitions, and other redundancies that were to be avoided in the compilation. Moreover, it took some time for the numbering system currently in use for the works to be implemented. The authors initially continued to refer exclusively to the »Thematisches Verzeichnis der Instrumentalwerke von Michael Haydn« (to which we have assigned the letter P) that Lothar Perger had presented in the Denkmaler der Tonkunst in osterreich (DTo). The »enumeration« by the American musicologist Charles H. Sherman (1929-2018) later began to Appear in the booklets. Sherman initially compiled a provisional catalogue and then in 1993 published Johann Michael Haydn: A Chronological Thematic Catalogue of his Works in collaboration with T. Donley Thomas. This chronological listing (MH) and the P numbers, which soon will be 120 years old, are used whenever possible for the identification of the works recorded here. Our wish is that this unique edition may bring you great pleasure.
