b. 97-100

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

Dashes till b. 100 in FC (→GE)

Dashes till beginning of b. 97 in FE (→EE)

..

Chopin was adding the dashes marking the range of dim. to the end of bar 100; however, it is uncertain which marks are written in his hand – probably already from the third dash, which would be compliant with the notation of FE, and certainly the last 5 dashes (bars 99-100). The version of FE (→EE) may be inaccurate, since dashes are generally added to indications valid clearly longer than the word defining a given indication.

b. 100-101

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

Slur to b. 101 in FC (→GE)

Slur to end of b. 100 in FE (→EE)

..

The longer slur of FC (→GE) resulted from a correction by Chopin, who in FC added an ending of the slur reaching the c1-e1 third.

b. 100-101

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

Slur to crotchet G in sources

Slur to C suggested by the editors

..

In the main text we give a slur resulting from the changes introduced by Chopin to FC, striving at integrating the beginning of the Mazurka main theme, that is the 1st beat of bar 101, with the preceding four-bar section, in particular the change of the chord to a single note, closing the bass line, and the extension of the R.H. slur. According to us, the fact that Chopin did not explicitly mark such an extension in the L.H. part is an oversight in the implementation of this wide-ranging change.

C in FC (→GE)

Chord in FE (→EE)

..

In the main text we give the FC (→GE) version, entered by Chopin instead of the crossed-out chord, preserved in FE (→EE). Chopin's correction also included the addition of  and of the pedalling and the extension of the R.H. slur.
