Issues : Errors resulting from corrections

b. 68

composition: Op. 10 No 4, Etude in C♯ minor

g-h-f2 in AI, FE & EE3 (→EE4)

g1-b1-f2 in EE2

g1-b1-f2 in GE1

g1-b1-f2 in GE1a (→GE2)

g1-b1-g2 in GE3

g1-b1-g2 in GE4 (→GE5)

..

A sharp erroneously placed in GE1 before g1 was substituted in GE1a (→GE2) by  confirming b1 in this chord. It was probably an engraver's mistake while moving  before the middle note of the chord which seems natural in this context. The reviser of GE3 "corrected" this unnaturally sounding chord, by changing its topmost note, although in this case too, one cannot exclude the engraver's error. The erroneous accidental was not corrected until GE4 (→GE5). The missing  in EE2 is clearly an oversight, corrected in EE3 (→EE4). The only correct version is the concurrent text of AI and FE.

b. 75

composition: Op. 10 No 4, Etude in C♯ minor

g2 in AI

g2 in FE (→EE)

g2 in GE

..

Lack of the  returning g2 in GE may reveal the fact that the sign was not added until the last proofreading of FE (→EE). The sharp became necessary here due to enharmonic changes in the notation of the previous group.
