DAS RHEINGOLD

"This piano score has been compiled on the basis of the edition of Rheingold in the critical complete edition of the musical works of Richard Wagner (Richard Wagner, Samtliche Werke, Vol. 10, I-II, edited by Egon Voss, Mainz 1988f.). The primary source for the edition of Rheingold in the complete edition was the first print of the score (E) which was published by Schott's Sohne, Mainz in 1873. Unfortunately, the source which would have been of greatest significance for revision purposes could not be utilised in the preparation of this edition. Wagner's autograph fair copy of the score which was included in Ludwig II's estate fell into the hands of Adolf Hitler in 1939 and has never been seen again since 1945. For this reason, it was necessary to make frequent reference to both the so-called compositional sketch (KS) and the first draft of the score (PE). For any questionable interpretations of E in the principle text, the variants in KS and PE have been added in small print or footnotes. This also applies to additional markings and alterations undertaken by Wagner during rehearsals for the first performances in 1876 which were recorded by his assistants, principally by Heinrich Porges. These variants are marked with the sign [1876]. Remarks in quotation marks reproduce Wagner's original comments. At certain points, reference has also been made to the records by Felix Mottl who was also present at the rehearsals and performances in 1876. Further relevant information can be found in the volumes of the complete edition." (Egon Voss, quoted from the foreword of the new Rheingold vocal score. translation by Lindsay Chalmers-Gerbracht)
