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.

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.

 was added to FC by Chopin. At the same time, it can be seen that he probably initially started writing , which he then turned to 'f' from . The result was a little bit clumsy, which is a possible reason why this indication was omitted by GE1 (it was added in GE2).

Long accents in FC

Short accent in b. 101 in FE (→EE)

Short accents in GE

..

Instead of the short accent in bar 101, which is present in FC (in Fontana's hand) and FE (→EE), Chopin entered into FC two long accents in bars 101 and 103 (deleting the Fontana accent in bar 101). We include this change in the main text. We consider both accents in GE to be short, although the one in bar 101 is slightly longer than the remaining ones on this page. This difference certainly was not regarded as significant by the persons reading the Mazurka text.
