b. 134-135

composition: Op. 50 No. 3, Mazurka in C♯ minor

..

In FE (→EE) the slur over the L.H. part starts already from the 1st crotchet in b. 134. It must be a result of misinterpretation of the notation of AF, in which the slur over the three chords encompasses them with plenty of margin. Moreover, in FE this slur reaches only the 3rd crotchet in b. 134, in spite of the fact that its ending is present in b. 135 – on a new line.
This inaccuracy was repeated in EE. See the previous note concerning the 1st beat of the bar.

b. 134-140

composition: Op. 50 No. 3, Mazurka in C♯ minor

3 long & 2 short accents in AF

5 short accents in FE (→EE)

5 long accents in GE

..

In AF the accents in b. 139-140 are clearly shorter than the three previous ones in b. 134, 136 and 138, hence we reproduce them as short. However, if we were to compare them to the distribution of the notes, it would turn out that they are actually the same length – each reaches more or less the middle of the triplet. Therefore, it is most likely that Chopin meant all of them to be long accents, the way it is clearly shown in GE.

Figuration from c4 in A

Figuration from b3 in FE (→GE,EE)

..

The version introduced at the stage of proofreading FE (→GE,EE), certainly by Chopin, is definitely an improvement – the connection with the previous bar is smoother, while the shape of the applied motif refers to b. 126-129. The notation of A does not include any of the two necessary flats to a3.

Separate slurs in FC (literal reading) & FE (→EE)

Continuous slur in GE

..

In FC the slur in bar 134, the last in the line, suggests that it should be continued, which is not confirmed by the slur beginning in bar 135 from the 1st note. We assume that they are separated slurs, as in FE (→EE), whereas in GE they were interpreted as a continuous slur.
