In the main text we give the fingering added by Chopin in a proofreading of FE (→GE). We do not include the specifying additions introduced by Fontana to EE.

b. 72

composition: Op. 10 No 12, Etude in C minor

Slur in A, literal reading

FE (→GE,EE), interpretation of A

..

It seems that the slur in A is written inaccurately, thus in the main text we give the interpretation adopted in FE (→GE,EE).

category imprint: Graphic ambiguousness

issues: Inaccurate slurs in A

b. 72

composition: Op. 10 No 12, Etude in C minor

Arpeggio sign in A

FE (→GE1GE2, →EE)

No mark in GE3 (→GE4)

..

The arpeggio in FE (→EE,GE1GE2) embraces only two lower notes of the chord. It is certainly a result of a misinterpretation of A. In GE3 (→GE4) the mark was omitted.

Dot in FE (→GE,EE

..

Most probably Chopin added the staccato dot in a proofreading of FE (→GE,EE). In A the reason for its omission could be a mistake whose correction required rewriting the entire bar.
