Alban Berg was enlisted to proofread the work, but his suggested corrections were never incorporated, while at the same time some unauthorised changes were introduced, possibly by one of the conductors of the first two performances, Franz Schalk and Alexander von Zemlinsky.
Alban Berg a fost angajat să corecteze lucrarea dar corectările sale sugerate nu au fost niciodată aplicate și, în același timp, au fost efectuate modificări neautorizate, posibil de unul dintre dirijorii primelor două interpretări, Franz Schalk și Alexander von Zemlinsky.
