Issues : Deletions in A

b. 8-9

composition: Op. 29, Impromptu in A♭ major

..

Chopin changed the hairpins' concept in A: he deleted the crescendo hairpins in bar 9 and he prolonged the ones beginning in bar 8. Probably both changes were introduced at the same time: Chopin deleted the short hairpins in bar 9, planning to introduce a longer crescendo indication. In order to do that, he added an extension of the hairpins' arm from bar 8 or even the entire hairpins in two moves (the too short sign and extension).

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.

Before the 11th quaver there can be seen a deletion in A; the deleted sign was probably an accidental.
