b. 130-132

composition: Op. 30 No. 4, Mazurka in C# minor

..

In this chromatic progression, the notation of the sources does not contain any mistakes, and Chopin took care of a few cautionary accidentals – to g1-b1 at the beginning of bar 130, to g1 in bar 131 and to d1-f1 in bar 132. In the main text we also add naturals to e in bar 130 and to B and a in bar 132. The latter were also added by GE (a  to B) and EE (a  to a).

b. 130-131

composition: Op. 30 No. 4, Mazurka in C# minor

Separate slurs in FC (→GE)

Continuous slur in FE (→EE)

..

The division of the slur in FC falls on such unnatural place that one could assume a misunderstanding in the reading of [A], e.g. caused by the transition into a new line in the autograph. Due to the above, in the main text we give the slur of FE, more reliable in this context.

b. 130

composition: Op. 49, Fantaisie in F minor

No R.H. lower voice in sources

Crotchet f suggested by the editors

..

The missing crotchet complementing the R.H. bottom voice in the sources is probably Chopin's oversight, which is indicated by a comparison with analogous bar 138 and 297. Such oversights of one of the notes in a multi-part texture happened to Chopin on a few occasions, e.g. in the Nocturne in B, Op. 62 No. 1, bar 33. In the discussed place, the possibility of making a mistake is increased by the corrections the traces of which are visible in the form of a deletion on the top stave.

b. 130

composition: (Op. 4), Sonata in C minor, Mvt I

Slur to 8th quaver in A (→GEFE,EE,IE)

Slur to 7th quaver suggested by the editors

..

Due to the reasons discussed in the note on bar 124, in the main text we provide a slur whose range we adopt from the remaining analogous bars. We consider the version of the sources, also musically justified, to be an equal variant. The A slur could have been extended by Chopin, yet it is an isolated incident among a few analogous situations.

b. 130

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A there is neither a  to the a2 quaver nor a  to the f3 quaver. Both accidentals were added in GE (→FE,EE,IE).
