It takes a historico-critical approach and seeks to document the history of the works and writings by shedding light on their transformations, thus identifying the various versions as witnesses of evolving aesthetic and historical positions. Eislers complete oeuvre (only a limited number of his works had penetrated the publics awareness up until the 1990s) first became the object of an editorial undertaking when the "Eisler - Gesammelte Werke" (EGW) was founded by Nathan Notowicz. It was later placed under the direction of Manfred Grabs and Eberhardt Klemm, and began issuing its publications in 1968 through the intermediary of the Deutscher Verlag für Musik in Leipzig. However, only four volumes of music and five volumes of writings were published. The Hanns Eisler Complete Edition pursues the work begun at that time, although it has had to fundamentally revise its editorial principles. In this respect, the Hanns Eisler Complete Edition can be considered as a completely new editorial undertaking. It became necessary to reconceive the organization of the volumes and series as well as the editorial guidelines in order to adapt the standards of historico-critical editing generally applicable today to the specific and sometimes singular circumstances of Eislers works.The Critical Commentaries pertaining to the main volumes follow the music section or, whenever they are too extensive, appear in a special volume.Series I: Choral MusicSeries II: Music for Voice and Instrumental Ensemble or OrchestraSeries III: Music for Voice and PianoSeries IV: Instrumental MusicSeries V: Incidental MusicSeries VI: Film MusicSeries VII: Sketches and FragmentsSeries VIII: Arrangements of works by other composersSeries IX: Writings, Letters and InterviewsSON 501 has been awarded the German Music Edition Prize 2003.SON 502 has been awarded the German Music Edition Prize 2007.
