Op. 49, Fantaisie in F minor

GE1 is based on A and was not corrected by Chopin. It contains traces of a detailed publisher’s revision, but nevertheless is not error-free.

The majority of revisions are accurate corrections of generally patent defects of A:

• numerous additions of overlooked accidentals, e.g. in bar 17 ( to g²), 18 ( to B), 50-52 ( to d¹, d²), 67 ( to G₁), 74-75 ( to e¹), 77-78 ( to d³, e³), 87-88 ( to a¹, a²), 91-92 (9 naturals to b, d), 106 ( to d¹, d², d³), 135-136 ( to d¹), 149-152 (8 flats to g);
• added cautionary accidentals, e.g. in bar 19 ( to c¹, c³), 27 ( to g¹);
• restored bass clef in bar 66.

However, certain defects of A remained unnoticed, e.g.:

• no  restoring b in bar 18,  restoring g¹ in bar 220 or  restoring g² in bar 265;
• no flats lowering g¹⁽²⁾ to g¹⁽²⁾ in bar 185 and 187;
• no  raising a¹ to a¹ in bar 274 and e to e in bar 289.

Among GE1 revisions, there is also a group of unobvious, arbitrary or clearly erroneous changes, e.g.:

• added L.H. articulation markings (staccato and slurs) in bars 1-16;
• moving the  in bar 9 between the staves;
• minor changes in the range of dynamic hairpins, yet sometimes influencing the interpretation, e.g. in bar 27, 109, 111 and analog., 110 and 114;
• moving the semiquaver beyond the 3rd triplet quaver in bars 77-78 and analog., contrary to the Chopinesque understanding of such combinations; similarly, at the end of bar 78, 80 and analog.;
• moving the L.H. slurs in bar 86 and 89-90 under the notes;
• prolonging the slurs (unclear in A) in bars 94-95 and 98-99, as well as 100-101.

Some mistakes committed in GE1 include:

• overlooking ties to a¹ in bars 14-15, b¹ in bar 17, B in bar 186;
• overlooking the R.H. bottom voice rest in bar 21;
• one-part notation of the R.H. chord in bar 25;
• inaccurately reproduced slurs, e.g. in bar 28, 78, 285-286, 321-322;
• inaccurately placed verbal indications, e.g. in bars 42-43, 62-63, 190-193;
• overlooked pedal markings in bar 48, 49-50, 188, 198 and 199-200;
• combining the crotchet stems with quaver beams in bars 47-50 and 58-59;
• overlooking  in bar 112, cresc. - - in bars 178-179, and slur in bar 234;
• overlooking the E₁ crotchet in bar 186;
• misplacing the tie to d¹ in bars 199-200.

There is some difficulty in determining which accents are short and which are long. Marks of different length were used, but the differences are so subtle that they seem to be of an accidental nature. Nevertheless, in many places one could try to differentiate between two types of marks, e.g. all accents on p. 16 of the copy are more or less 1/3 times longer than the ones in bars 290-302.
