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.

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. 137-139

composition: Op. 2, Variations, complete

..

In these bars, in AsI the L.H. part is marked in an abridged manner with the word unisono, written in each bar. There is a similar situation further on, until the end of this variation (b. 167).

b. 137-138

composition: Op. 2, Variations, complete

..

In AsI the accidentals restoring c1 and b at the end of b. 137 are missing; the  raising e1 to e1 in b. 138 is absent too. A similar situation occurs in the L.H. part, which is marked in an abridged manner as doubling in unison the R.H. part. In A and the editions the notation is correct.

b. 139

composition: Op. 2, Variations, complete

..

In the main text we add a cautionary  to f and f1 and a  to e1 and e2, as well as to e1 in the alternative harmonic and rhythmic accompaniment (the latter was also added by GE3). We also include the  to g1 and g2, which Chopin entered already into A. A similar situation is in b. 147 and 163.
