b. 66-68

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

No slur in AI

Two-bar slur in FE (→GE,EE2)

Three-bar slur in EE3 (→EE4)

..

In this context, the missing slur in bar 68 must be considered as inaccuracy of notation. Therefore, in the main text we suggest to extend the slur from bars 66-67. A similar interpretation of slurring was already performed by the reviser of EE3 (→EE4).

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.

a1-c2-a2 in AI

c2-d2-a2 in FE (→GE,EE)

..

The chord of AI is undoubtedly the original version, improved by Chopin probably still in [A].
