b. 98

composition: Op. 25 No 10, Etude in B minor

No fingering in GC (→GE1), FE & EE1

Fingering in EE2 (→EE3)

..

Nothing proves the authenticity of the fingering added in EE2 (→EE3).

category imprint: Differences between sources

issues: EE revisions

b. 100-101

composition: Op. 25 No 10, Etude in B minor

in GC (→GE) & EE

No second part of indication in FE

..

The sotto voce indication was completed in GC and probably in the base text to EE. In GC one can see that Chopin initially wrote a different indication (probably e legato only), to eventually choose e sempre legato.

b. 103

composition: Op. 25 No 10, Etude in B minor

Slur ended in GC, FE, EE & GE2 (→GE3)

Slur continued in GE1

..

The slur of GE1 is a consequence of literal interpretation of an inaccurate slur of GC in bar 104.

issues: Inaccuracies in GE , GE revisions

b. 104

composition: Op. 25 No 10, Etude in B minor

in GC, EE & GE2 (→GE3)

in FE & GE1

..

Same as in bar 1, FE and GE1 give the non-authentic  time signature.

b. 104

composition: Op. 25 No 10, Etude in B minor

Continued slur in GC (literal reading→GE1)

New slur in GC (contextual interpretation), FE, EE & GE2 (→GE3)

..

The first slur in the R.H., in GC started too early and moved to the left, confused the engraver of GE1 who combined it with the previous one. The remaining inaccurate slurs of GC in this bar were interpreted correctly, in accordance with the version of the remaining sources.
