composition: Op. 10 No 10, Etude in A♭ major

..

The notation of accidentals in these bars is very careless in A, although it does not lead to textual doubts. In bar 37 Chopin omitted the flats before the 1st (g), 2nd (g1) and 9th (c1) notes in the L.H. and before the upper note (c4) of the sixth on the 2nd quaver in the R.H. Moreover, the  lowering g2 to g2 is written only before the last quaver in the R.H. In bar 38 there are no flats before the 4th (g) and 5th (g1) notes in the L.H. In FE only the first necessary flats in the parts of both hands in bar 37 and a cautionary  before c2 in bar 38 were added. In GE all necessary signs and a superfluous  before c3 on the 8th quaver in bar 37 were added. In turn, the cautionary  in bar 38 was not included, which probably means that it was added during the last stage of proofreading of FE. EE also has the correct notation, including the aforementioned natural. At the same time, EE3 gives only the necessary signs, while in EE4 two unnecessary flats featured in GE were also added.

In A (→FE) there is no  raising d2 to d2 on the 5th quaver and the  lowering g1 to g1 on the 11th quaver. These patent errors were corrected in GE and EE.
