The Leipzig Edition of the Works of Felix Mendelssohn Bartholdy is intended to afford public access to all the available compositions, letters, writings and other documents relating to the artistic work of Felix Mendelssohn Bartholdy in an appropriately scholarly form. As a historico-critical edition, it aims to be of equal value to researchers and practicing musicians alike.
The musical works take pride of place. Next to completed compositions in all their versions, the Leipzig Edition also presents the sources underlying the creative process (sketches and drafts) as well as unfinished compositions (fragments). In addition, Mendelssohn’s letters are extremely important. It is generally acknowledged that reliably edited correspondence is indispensable for the scholarly study of any composer’s work. In Mendelssohn’s case, however, the correspondence is of particular significance, not only because it reveals the composer to be an outstanding witness of his time, but also because of the exceptional literary merit of many of his letters. Finally, if one wishes to provide a comprehensive picture of Mendelssohn as an artist, his pictorial works of art, principally drawings and watercolors, cannot be overlooked. The Work Catalogue, which is being published first in a study edition, aims to hasten and facilitate access to the composer’s Oeuvre.
A comprehensive study like this hardly calls for lengthy justification, given both Mendelssohn’s importance as a composer and his neglect by the scholarly and musical world alike, essentially attributable to non-artistic motives. The edition of Mendelssohn’s works published by Julius Rietz between 1874 and 1877 and often erroneously referred to as Alte Gesamtausgabe, was anything but complete, and unlike the Old Bach Edition, for example, was not compiled with any intention of presenting Mendelssohn’s complete works, hence its modest title, Felix Mendelssohn Bartholdy’s Werke. Kritisch durchgesehene Ausgabe. As a consequence of Rietz’s selection, a considerable amount of Mendelssohn’s compositions still awaits publication to this day, while others have been published only in an inadequate form. The few volumes of the new edition which have been published since 1960 by Deutscher Verlag für Musik, Leipzig, have failed to make any major change to this state of affairs.
As regards the chronological arrangement of the compositions to be edited, the present publication conforms to this Leipziger Ausgabe der Werke Felix Mendelssohn Bartholdys, but generally takes account of the latest principles governing the publication of complete scholarly editions. This refers in particular to the tenet that all the editor’s decisions – whether relating to the score itself or to the Kritischer Bericht (Critical Report) – must be clearly stated and made accessible to the critical understanding of the user. In addition, the edition conforms to the view generally accepted today that every stage of the composing process or of the publication attributable to the composer himself (sketches, different versions, his own transcriptions such as piano scores) forms part of the work itself.
This view is particularly pertinent in the light of the specific musico-historical situation in Mendelssohn’s day, which led him to fulfill the aesthetic demands attendant on a definitive, self-contained work of art in highly differing degrees of perfection. This is evidenced not only by the differing versions of numerous works, but also by the fact that the composer himself considered many completed works not worth publishing. This hampers a differentiating hermeneutic approach to the sources, which must precede any editorial decision, and a pragmatic approach on the part of the editor. At the same time, however, it provides an opportunity for the development of exemplary methods for the editing of unfinished or otherwise incomplete compositions.
A particularly problematic situation results from the fact that Mendelssohn only gave opus numbers to the works which he published or prepared for publication. Many of his works have thus come down to us without authorized opus numbers. Nevertheless, the opus numbers from 73 onward have long since come into general use, in part through the aforementioned edition supervised by Julius Rietz. The present edition takes this into account by continuing to use these opus numbers, albeit placing them between square brackets.
