Long accents in A

Short accents in FC (→GE) & FE (→EE)

..

In A all accents in b. 6, 8 and 14 are clearly long, which, however, was misunderstood both in FC (→GE) and FE (→EE).

b. 35-36

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

Slur from 2nd quaver in A

No slur in FC (→GE)

Slur from first quaver in FE

Continued slur in EE

..

The slur of A begins from the 2nd quaver, which we give in the main text. In FE and EE the slur starts earlier (in FE from the 1st quaver, while EE continue the slur from the previous line), which we deem inaccurate. In FC (→GE) the slur was overlooked. As far as the ending of the slur is concerned, since in the entire Prelude it is slurs/tenutos that prevail in similar situations – see the note to b. 4-5 – to the main text we adopt such an interpretation, compliant with FE (→EE).

b. 54

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

 under 3rd quaver in A (→FCGE)

 under 2nd quaver in FE (→EE)

..

Chopin prolonged pedal in this place, which is proven by  having been crossed out at the end of b. 53 (which we can see in A). The composer's intention was distorted in FE (→EE) by placing the mark a quaver earlier. A similar shift of the  mark (for the pedal to encompass the first octave of the chromatic bass sequence) can also be seen in A in b. 50.
