b. 9

composition: Op. 10 No 5, Etude in G♭ major

..

We add a cautionary  before d1; it was already performed in GE and EE4. We remove the unjustified  before c1 in the 2nd chord; the change was already introduced in GE and EE4.

b. 9-10

composition: Op. 10 No 6, Etude in E♭ minor

Two slurs in A, contextual interpretation

One slur in FE (→GE,EE)

..

Two slurs in A are clearly shorter than their counterparts in bars 1-2, however, there is no doubt that it is a result of a less careful notation. In FE (→GE,EE) it was understood in the same way, yet only the second slur, in bar 10, was reproduced. See bars 1-4.

b. 9

composition: Op. 10 No 7, Etude in C major

Slur in A (→FEGE,EE)

Our suggestion

..

The shorter slur featured in the sources may be considered as inaccurate, therefore, we suggest to begin it earlier, after the majority of similar slurs (cf. the remark on bar 1).

b. 9-10

composition: Op. 10 No 7, Etude in C major

Two accents in A

Long accent in FE (→EE)

Short accent in GE

..

In FE the type of the accent in bar 9 (short or long) is not obvious – in GE it was reproduced as short, in EE – as long. In FE (→GE,EE) the short accent in bar 10 was overlooked. In FED Chopin added a long accent in bar 9, confirming the printed sign.

b. 9-15

composition: Op. 10 No 9, Etude in F minor

..

In AI bar 8 is marked as 1ma [volta], after which bar 16 follows, marked as 2[da volta]. However, after bar 8, instead of the expected repeat sign, there is a double bar line. In spite of this inaccuracy, there is no doubt that bars 9-15 are meant to be repetition of bars 1-7. A double bar line appears also after bar 16.
