I read on the Henle Verlag website that Liszt "simplified" his Mephisto Waltz for a friend.Does anyone know about this and where can I get the sheet?I'm also looking for the Piano Duet sheet.Thanks.
The abridged and simplified edition is included in the book.https://www.henle.de/us/detail/index.html?Titel=Mephisto-Walzer_763
