Issues : Errors repeated in EE

b. 13

composition: Op. 28 No. 19, Prelude in E♭ major

..

In A there is no  lowering g1 to g1 in the 1st triplet and no  raising f1 to f1 in the 3rd triplet. What is more, the crossing-out before the first note suggests that Chopin crossed out the initially written  (see b. 29). The accidentals were added in GE and EE2 (in EE1 only the ).

In A (→FC,FEEE1) there is no  raising e to e. The inaccuracy was corrected in GE and EE2.
In the main text we add a cautionary  before g (Chopin added a respective accidental only before g1 in the R.H. part). It was already added in EE.
