b. 7

composition: Op. 29, Impromptu in A♭ major

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.

At the beginning of the bar, in A one can see a deleted fragment of the R.H. part. The editors have not succeeded at deciphering the deleted text.
