b. 6-13

composition: Op. 28 No. 8, Prelude in F♯ minor

..

As was the case in b. 3-4, in A Chopin generally omits accidentals next to the bass quavers if the accidentals have been written an octave higher next to one of the preceding semiquavers. In the discussed bars it concerns in b. 6, c1 and b in b. 7, and g in b. 8, in b. 9 and 11, B and in b. 11, B in b. 12 and G in b. 13. That notation was literally repeated in FE; in FC almost without changes (only one  added next to B in b. 11). The remaining editions added the majority of the necessary accidentals – in EE1 all except for the  next to G in b. 13, while in GE1 all except for the naturals next to f in b. 6 and G in b. 11 (in GE2 the former was added). It is only EE2 that includes a fully correct notation.

b. 6

composition: Op. 28 No. 8, Prelude in F♯ minor

In the main text we add a cautionary  before f2. We also keep the cautionary  before d1 in the L.H. part, present in all sources.

b. 6-11

composition: Op. 28 No. 9, Prelude in E major

..

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 (→FCFE) and CGS there is not a single out of 8 necessary accidentals –  before and in b. 6, g in b. 7, in b. 9-10, 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 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 in b. 6 and 10 and the  before d in b. 11 were overlooked;
  • EE2 added to them only  before in b. 6 and 10.

Slur to in sources

Slur to g suggested by the editors

..

In the sources the slur reaches only the last semiquaver in b. 6. A comparison with analogous situations in b. 2-3, 10-11 and 14-15 proves that it is almost certainly a result of inaccuracy of A.
