b. 136

composition: Op. 2, Variations, complete

Triad in A (→GEEE,FESB)

Sixth in FE

..

In the main text we give the proofread – almost certainly by Chopin – version of FE, with a "lighter" sixth instead of a three-note chord. A similar situation is in b. 144 and 160.
In AsI the alternative version of the L.H. was not written out in this bar – see b. 135-139.

b. 136

composition: Op. 2, Variations, complete

  in A

  in GE (→FE,EE,FESB)

..

As in the next bar, in A the change of direction of the   hairpins occurs just before the three quarters of the bar. In GE and the remaining editions, this moment occurs in the middle of the bar, contrary to the natural dynamics related to the direction of the figuration movement.

b. 136-137

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

New slur from d2 in FC (→GE)

New slur from c2 in FE (→EE)

..

In FC, the continuous slur written initially by the copyist, encompassing the last 5 bars, was divided into two slurs by Chopin between the 2nd and 3rd beats of this bar. We give this version, undoubtedly Chopinesque and present in the principal source, in the main text. On the other hand, the authenticity of the FE (→EE) version is uncertain, since one can easily imagine that the Chopinesque notation, either in [A] or in the proof copy of FE, could have been misinterpreted. Chopin could have, e.g. written the following, inaccurate slurs: , which in FE were interpreted in accordance with the tendency to adjust marks to regular rhythmic structures, e.g. bars, typical of engravers.
The crossed-out fragment of the initial, continuous slur visible in FC comes from the reviser of GE1, who thus clarified the slurring correction entered by Chopin.

b. 136-139

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

slentando in FC (→GE)

smorz. - - in FE (→EE)

..

Chopin entered slentando into FC (→GE). Similarly, Chopin added the smorz. - - indication present in FE (→EE) probably only just while proofreading this edition.
Therefore, both indications, of a similar meaning, can be regarded as equal variants.
