BWV Anh.
BWV Anh., abbreviation of (German for Bach works catalogue annex), is a list of lost, doubtful, and spurious compositions by, or once attributed to, Johann Sebastian Bach. History. First edition of the "Bach-Werke-Verzeichnis" (1950). In 1950 the "Bach-Werke-Verzeichnis" was published, allocating a unique number to every known composition by Bach. Wolfgang Schmieder, the editor of that catalogue, grouped the compositions by genre, largely following the 19th-century (BG) edition for the collation (e.g. BG cantata number = BWV number of the cantata): The of the BWV listed works that were not suitable for the  main catalogue, in three sections: Within each section of the the works are sorted by genre, following the same sequence of genres as the main catalogue. Second edition of the "Bach-Werke-Verzeichnis" (1990 and 1998). Schmieder published the BWV's second edition in 1990, with some modifications regarding authenticity discriminations, and more works added to the main catalogue and the . A strict numerical collation was abandoned to insert additions, or when for another reason compositions were regrouped. Authenticity discriminations, based on new research, could lead to such repositionings within the catalogue, e.g. "" became "" indicating it was now considered a  spurious work. In 1998 Alfred Dürr and Yoshitake Kobayashi published a small edition of the catalogue, based on the 1990 second edition. This edition, known as BWV, contained a few further updates and collation rearrangements. New additions (Nachträge) to BWV/BWV included: A few exceptions to the principle that compositions weren't renumbered were when a composition from the could be recovered and/or authenticated as Bach's, so that it deserved a place in the main catalogue, in which case it was given a number above 1080. So, for example, BWV Anh. 205 (BWV) → BWV 1121 (BWV, where it  is in section 7 as a work for organ). Other renumberings and additional numbers involved alternative or earlier versions of basically the same composition, which were indicated by adding a lower case letter to the BWV number. For example, was renumbered to BWV 149/1a (earlier abandoned version of the opening movement of Cantata BWV 149) Slashes indicate movements: e.g. BWV 149/1 indicates the first movement of the Cantata BWV 149. Another example: the Agnus Dei of the Mass in B minor can be indicated as BWV 232/22 (22nd movement of the composition), or alternatively as BWV 232/4 (BWV 232, fourth  movement of Part IV). Section::::"Bachs Notenbibliothek" (1992). published "Bachs Notenbibliothek" (BNB) in 1992. As a compendium of works in Bach's musical library, it listed as well Bach's own compositions, as works by other composers of which Bach owned a copy. Several compositions of this latter group are listed in the BWV Anh. (mostly Anh. III). For example, the Kyrie–Gloria Mass for double choir, BWV Anh. 167, is listed as BNB I/An/3 in Beißwenger's catalogue. 21st century. As of mid-2018 the Bach Digital website started to implement the new numbers of the next edition of the  Bach-Werke-Verzeichnis. The editors of this third edition of the "Bach-Werke-Verzeichnis" (projected to be published in 2020) recognise that the BWV Anh. has become largely unworkable, calling for a new approach. List.
