b. 42

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

..

In the sources there is no  returning fat the penultimate semiquaver. Due to the unquestioned f1 in the R.H., lack of this sign must be considered as a patent error.

No b in FE (→GE,EE)

Renouncement of the b semiquaver in the final version finalises the changes whose trace is visible in the deletions of AI:

  • originally, the passage in the R.H. started with an a1, while the remaining elements of the ninth chord were in the part of the L.H.; 
  • starting the passage with b1 caused a doubled third of the dominant chord, which Chopin did not like and which he eventually avoided by deleting b.

The four bottom notes of the chord of AI are written as semibreves.

We add cautionary accidentals before the chord. The natural before a1 was already added in GE4 (→GE5).

b. 46

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

..

In AI there are no naturals before the 4th and 12th semiquavers (in both hands). The signs in the 1st half of the bar are of cautionary significance, yet in the 2nd half of the bar they are necessary. Moreover, the  lowering d1 to d1 was omitted. All the aforementioned signs appear in FE (→GE,EE).
