b. 216

composition: Op. 2, Variations, complete

2 staccato dots in A, probable reading

No marks in remaining sources

8 staccato dots suggested by the editors

..

Both dots visible in A over the first two R.H. semiquavers are quite far from the notes and clearly not in the same line (vertically speaking); therefore, one wonders whether they are not accidental spots. However, the dots are clear and regular, while the shifts with respect to the notes they probably concern are similar both in terms of distance and direction. Therefore, we assume that they are staccato dots with which Chopin indicated a slightly different type of articulation – most probably lighter – of the  semiquavers. In the main text, for the sake of clarity, we suggest adding dots in the entire 1st half of the bar.
The markings were not included by GE1 and the remaining editions, perhaps due to the atypical placement described above.

Given g in the previous and next bars, we may assume that also the middle note of the chord in the second half of b. 25 was intended by Chopin to be g and he must have overlooked . However, the version is no less musically satisfactory, and so, assuming Chopin did not make a mistake, we provide this version for the main text.

FE1 does not have  for the topmost note of the chord in the L.H. That obvious omission was corrected in FE2.

Fingering written into FEJ

No teaching fingering

The sign added in crayon in FEJ probably means the fingering number, '1'.
