b. 5

composition: Op. 29, Impromptu in A♭ major

 
 
 
..

In A the end of tie reaches the next bar. We consider it to be an inaccuracy of notation due to the obvious phrase structure and consistent slurring in almost each out of 11 analogous bars.

b. 5

composition: Op. 27 No 1, Nocturne in C# minor

..

We add a cautionary natural before e2. This sign is also supplemented in EE.

b. 5-13

composition: Op. 27 No 1, Nocturne in C# minor

GE (→FEEE): semiquaver after the last note of the triplet

Notation in keeping with Chopin's understanding of this figure

..

In bar 5 in GE (→FEEE) the semiquaver in the figure  is moved to after the third note of the triplet in the accompaniment, similarly in bars 9, 11 & 13. This inauthentic notation, misleading for the performer, was used throughout the Nocturne – cf. bars 15, 51, 88, 89.

composition: Op. 27 No 2, Nocturne in D♭ major

A long accent in A (→GE2) and FE

A short accent in GE1 and EE

..

The accent over a1 is doubtless a long one in A; this is testified by the change made in GE2 (probably after a repeated analysis of A). The sign in FE is not quite clear, yet it resembles a long accent more than a short one. In spite of that, EE has a short accent over the note in question.
