b. 14

composition: Op. 2, Variations, complete

Long accent in A

in GE (→FE,EE)

No sign in FESB

..

The traces of erasure visible in A reveal that Chopin initially inserted the  mark under the bottom stave, more or less there where it is to be found in the editions. It can also be seen that the initial mark was longer, since it reached the first L.H. quaver. The corrected version of the mark was shortened and moved over the first chord. In this form, the mark is to be interpreted as a long accent, which we give in the main text. The engraver of GE (→FE1,EE) moved the mark, which he most certainly considered a diminuendo, under the stave, probably to avoid a contradiction with poco cresc. or simply due to lack of space over the stave (a hairpin on the stave is poorly visible; such a solution is applied only in exceptional cases).
The fact that the mark is absent in FESB is most probably due to an oversight, one of a few in this bar.

The missing ten. must be an oversight or revision (the stem prolonging bwas also overlooked/omitted).

leggier. in A (→GEFE,FESB)

leggiero in EE

..

In the main text we keep the ambiguous Chopinesque abbreviation leggier. We assume that the abbreviation most likely stands for the adverb leggier(a)mente, which Chopin used a few times in his other early works (cf., e.g. the Concerto in F minor, Op. 21, III mov., b. 81). Another possibility could be leggierissimo, which, Chopin, however, would abbreviate as leggieriss. – cf. b. 55 and 367. The word leggiero featured in EE almost certainly does not literally correspond to Chopin's intention but, practically, being synonymous with leggiermente, it can be considered an unequivocal version of the Chopinesque abbreviation.
