b. 6-16

composition: (Op. 4), Sonata in C minor, Mvt II

..

In the sources, at the beginning of bar 6, there is a double bar line provided with  marks, indicating the place from which the first period of the Minuet should be repeated after bar 37. Chopin did not write bars 38-48 but wrote Dal Segno al Fine at the end of bar 37, directing us to bars 6-16. We reproduce this shorthand notation only in the graphic transcription (the version "transcript").
In EE1 the  marks were overlooked, which was corrected in EE2. In FE the word Fine was replaced by its French counterpart, Fin.

In FE the mordent's sign was probably omitted. What is puzzling is the fact that there is no relevant entry in pupils' copies (e.g. in bar 21 Chopin added the omitted sign to FES and FEJ).

The crescendo hairpins differ slightly in their range. In comparison with A (→GE), in FE the hairpins are extended on the entire penultimate triplet group. In EE they are totally absent (cf. remark concerning bars 7-9).

EE is lacking dynamic indications. It must be an omission, as it concerns the entire line of the text.

..

A, FE and EE are lacking in the natural raising d3 to d3. The sign was added in GE.
In the entire Impromptus Chopin rather treated the accidentals as valid regardless of the octave in which the altered pitch appeared; therefore, it is difficult to clearly consider the absence of that sign as an omission.
