b. 8

composition: Op. 10 No 2, Etude in A minor

No dot in CLI, GE & EE

Dot in Ap & FE

..

In the main text we consider the staccato dot, visible over the 1st octave in Ap and FE. It is hard to determine what caused the sign's lack in both GE and EE.

b. 8

composition: Op. 10 No 2, Etude in A minor

No indication in CLI, Ap & GE4 (→GE5)

dim. in FE (→EE,GE1GE2GE3)

..

In the main text we give the dim. indication written by Chopin in FEcor (→FEEE). In GE1 (→GE2GE3) an extended, dimin. form was used, and in later GE,s the indication was omitted.

..

On the 4th beat of the bar there is a superfluous  before g1 in the manuscripts (cf. bar 4).

b. 8

composition: Op. 10 No 11, Etude in E♭ major

 signs in A

 sign in FE (→EE)

No signs in GE

 
..

A includes two  marks, out of which only the 1st one was reproduced in FE (→EE). In GE there is however not a single one of them, which can indicate that even the one included in FE could have been initially overlooked and reintroduced by Chopin only during the last proofreading. In the main text we give both marks written in A, yet leaving the consideration of the second one, present only in the manuscript, at the performer's discretion.

b. 8-9

composition: Op. 10 No 11, Etude in E♭ major

..

In the main text we adopt the quaver tie system applied by Chopin in A. In FE (→GE,EE) the ties in the L.H. may have been changed due to graphic difficulties, embracing three last quavers in bar 8 with one tie and providing the 1st quaver in bar 9 with a stem. In GE3 a similar tie system was applied in bar 8 also in the case of the R.H.
