As was the case in the Prelude No. 8 in F
Minor, Chopin assumed that the middle notes of the triplets did not require an accidental if a respective accidental had been written before a top-voice note placed an octave higher. In A (→FC→FE) and CGS there is not a single out of 8 necessary accidentals – 
before c and d in b. 6, g in b. 7, c in b. 9-10, d in b. 10-11 and a 
before d in b. 11. The remaining editions added the majority of accidentals; however, none of them features a fully correct text:
- GE1 added 6 accidentals – the before c in b. 10 and the before d in b. 11 were overlooked;
- GE2 added to them only a in b. 11;
- EE1 added 5 accidentals – the before d in b. 6 and 10 and the before d in b. 11 were overlooked;
- EE2 added to them only before d in b. 6 and 10.
