Issues : Omission of current key accidentals

composition: Op. 28 No. 17, Prelude in A♭ major
..
In the version prepared for print, the top note of the chord on the 5th quaver in the bar, interpreted literally, is an f1, since it is not accompanied by a relevant accidental in this bar. The following arguments prove that it was almost certainly Chopin's mistake:

A natural before the bottom note of the 1st bottom R.H. voice quaver (e1) is present only in EE, the only one in which this patent inadvertence of Chopin was corrected.

In A (→FC,FE) accidentals were inserted very inaccurately – in total, 4 sharps and 12 naturals are missing – which, however, does not impede the determination of the correct text. Accidentals were being added in GE and EE, although it is only in EE2 that the notation is totally correct. The naturals before the b-b1 octave in b. 44 were also added in FED. category imprint: Interpretations within context; Differences between sources issues: Annotations in teaching copies , EE revisions , Annotations in FED , Accidentals in different octaves , Errors in GE , GE revisions , Omission of current key accidentals , Inaccuracies in A , Errors repeated in FE , Errors repeated in EE |
