b. 10

composition: Op. 29, Impromptu in A♭ major

In A Chopin drew the end of the slur until the very end of the bar. We consider it an insignificant for the content graphic detail, as the tenuto of the d2 crotchet is indicated by the tie.

composition: Op. 29, Impromptu in A♭ major

In A the entire 2nd triplet in L.H. was corrected several times (probably it concerned the 1st and 3rd quaver). Eventually, Chopin deleted it and wrote the correct version on the pentagram below.

In A one can see corrections of the last quaver in L.H. in bar 10 and the 3rd quaver in bar 11. In both places Chopin changed d1 into b.

According to us, the more probable is such an interpretation in which the beginning of the slur includes the 1st note of the marked motif. In GE1 the slur was interpreted in a different manner: it begins a quaver earlier. EE has a similar slur, which may also comply with A's notation. FE is lacking the slur, while in GE2 (→GE3GE4) the slur which started in bar 9 runs until the end of bar 12.

We add a cautionary natural next to at the beginning of the bar. The sign was already added in GE2 (→GE3GE4).
