b. 47-49

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

..

In AI Chopin wrote the 12th semiquaver in bars 47-48 (and in bar 49, marked as repetition of bar 48) as f1. In FE (→GE,EE) the note is written as g1, as a result of which the next note has to be provided with a .

In the last group of semiquavers, in the place where FE (→GE,EE) has a b1, in AI there is a c2. By introducing this clearly justified correction, Chopin did not check its result precisely – in FE (→GE1GE1a,EE) there is no  before c2, still necessary despite the change of the previous note from c2 to  b1. This patent oversight was corrected in GE2 (→GE3GE4GE5).

b. 54-56

composition: Op. 28 No. 17, Prelude in A♭ major

..

In these bars the version of FCI clearly deviates from the final one – different harmonic rhythm in b. 54 and different shape of the melody in b. 55-56. We can also observe small changes to the arrangement of chords and enharmonic notation.

composition: Op. 25 No 2, Etude in F minor

In AW the first crotchet was originally an a2, which Chopin changed to b2. At the same time, the consequences of the change were not checked – there was still a  before the 2nd quaver (a2), superfluous in the new situation, while b2 was not returned on the 6th quaver. Preparing the piece for print, the composer returned to the initial notation.
