b. 197

composition: Op. 39, Scherzo in C♯ minor

B1 in EE, GC (→GE) & FE

B2-B1 proposed by the editors

..

Missing from the sources is the lower note of the L.H. octave, B flat2. As the range of Chopin's piano only reached C1, the addition seems more than justified here. Cf. bar 491

b. 197-201

composition: Op. 38, Ballade in F major

No slur in A (→EE,GCGE)

Slur in FE

..

The L.H. slur added in FE is one of a few elements indicating a perfunctory revision (by the editor, Fontana, Chopin?) of FE1. We give it in the main text because this phrase echoes the beginning of the Ballade, where parts of both hands were provided with slurs by Chopin.

b. 197

composition: Op. 38, Ballade in F major

..

In the main text we add cautionary naturals before a and b in the L.H., and a2 and b2 in the R.H. The cautionary naturals were also added in GE1 (before b2), and further ones in GE2 (→GE3) – before aa1 and a2.
The  before a2 was written into A in the first, deleted attempt to notate the grace notes – Chopin started to write them with stems downwards but changed his mind after having written two of them. It is hard to determine wether the omission of the  in the ultimate record was deliberate or accidental.

b. 197

composition: Op. 38, Ballade in F major

Staccato dot in A (probable reading→GC)

Wedge in A, possible reading

No mark in EE, FE & GE.

..

It is not completely clear whether the staccato mark in A is a dot or a wedge. In the main text we give a dot for despite its irregular shape the mark is similar in size to a dot. That is how it was also understood by the copyist. In EE, FE and GE, probably due to a mistake, the mark was omitted.

b. 197-199

composition: Op. 35, Sonata in B♭ minor, Mvt I

No marks in the sources

Accents suggested by the editors

..

According to us, no accents in bars 197 and 199 can be considered to be an oversight of Chopin – see bars 185-188.
