b. 43

composition: Op. 10 No 7, Etude in C major

Crotchet rest in A

Quaver rests in FE (→GE,EE)

..

We conserve the characteristic for Chopin prudent notation of the rest with the use of only one sign. The change introduced in FE (→GE,EE) could have been the engraver's routine action and performed without Chopin's participation.

b. 45-47

composition: Op. 10 No 7, Etude in C major

Two long accents in A

 in FE (→GE,EE)

..

According to us, the marks, written in A at the end of bars 45 and 47, should be interpreted as long accents. In FE (→GE,EE) the mark in bar 45 was given a form of  hairpins, while the mark in bar 47 was omitted.

b. 45

composition: Op. 10 No 7, Etude in C major

No sign in A

 in FE (→GE,EE)

..

The  hairpins added in a proofreading of FE (→GE,EE) should be considered to be authentic.

b. 45

composition: Op. 10 No 7, Etude in C major

Long accent in A

Short accent in FE (→GE,EE)

..

In A the characteristic placement of the sign slightly after the note indicates a long accent. In the editions it was reproduced as a common short accent.
