The differing abbreviated notation of AI and A could suggest that in the latter all four notes are supposed to have normal ("big") note heads. According to us, the notation of A, despite being simplified, is to be, however, interpreted in accordance with AI – in A we see the same abbreviation also in bar 36, in which the distinction of only the first A is beyond any doubt. Similarly in bar 19.

In GE1 (→GE1a), the first F in bar 18 is written as a small note. The mistake was corrected in GE2 (→GE3).

b. 19

..

The difference between the abbreviated notations of AI (repetition signs for 2 last figures) and A (signs for all 3 last figures) could suggest that in the latter all four notes are supposed to have normal ("big") note heads. According to us, the notation of A is to be interpreted as a simplified version of the notation of AI, which is also confirmed by FE and EE.
In GE1 (→GE1a), the note on the 2nd beat of the bar is also written as "big", which was corrected in GE2 (→GE3).

b. 19-20

composition: Op. 25 No 1, Etude in A♭ major

4 big notes in AI & EE1

8 big notes in A, FE & GE1a (→GE2GE3)

Small notes in CDP & EE2 (→EE3)

5 big notes in GE1

..

In the main text we give the version of A, confirmed by FE and most probably by Chopin proofreading of GE1a (→GE2GE3). The notation of GE1 is erroneous, while AI and EE1 include the original concept of separating the tenor voice only in the part creating a descending melodic line. The versions of CDP and EE2 (→EE3) are certainly non-authentic.

..

The version of the 1st half of the bar, written in AI, A (→CDP,GE1) and EE is undoubtedly earlier. Chopin introduced the final version in proofreadings of FE and GE1a (→GE2), probably in order to avoid parallel octaves at the transition from the previous bar (cf. the commentary to the Etude in A minor, Op. 25 No. 4, bar 60). GE3 arbitrarily reinstates the version of A.

a1 in AI & GE1a (→GE2GE3)

f1 in A (→CDP,GE1), FE & EE

..

Chopin changed the lowest note of the 3rd sextuplet in the R.H. twice:

  • AI has an a1, which in A was deleted and changed to f1. The change was somehow forced by the modification of the part of the L.H., in which Chopin renounced the note. It is also GE1EE (with a preserved in the bass) and FE, which has as the bass note, that have the changed version.
  • While proofreading GE1a (→GE2GE3), Chopin changed this note again, this time reinstating a1. This version also seems to be related to the modification of the part of the L.H., in which it was the note that became the bass one. We give this version in the main text, as it is the latest. However, Chopin was not consistent, as in FE – in spite of the change in the bass – he left a f1.
