New Liszt Edition Supplement 'A'
Though the primary purpose of the NLE is still the publication of the final form of each work, an earlier version of many of the works, where this differed significantly from the final form, has been included in the appendices to the volumes, especially in the second series.
The NLE Supplement volumes which have been published from 2005 are the successors of those appendices; in making available the earlier versions, their function is to enable the reader to look into Liszt's compositional workshop and to provide an opportunity for pianists and musicologists alike to form a closer acquaintance with Liszt the creative artist. Publication of the Supplement volumes is also justified and supported by the quantitatively and qualitatively significant achievements of Liszt philology in recent decades in the field of research into sources. These findings are, as always, fully taken into account and utilized by the NLE editors in preparing the Supplement volumes for publication.
The main aim of the editors, Adrienne Kaczmarczyk and Imre Mező in compiling the Supplement volumes has been - as befits the complete edition of an oeuvre - to make accessible here, in the case of every solo piano work, the earlier versions published at the time by the composer or others. In addition, they have included in them complete, fully worked out compositions and earlier versions surviving in manuscript form which are of indubitable musical value and thus may find a place in the concert repertoire.
