b. 281-282

composition: Op. 16, Rondo in E♭ major

Hairpin in FE (→GE)

No mark in EE1

Hairpin in EE (→EE3)

..

In EE1, the engraver overlooked the ​​​​​​​ hairpin. The mark was added already by the reviser of EE2 (→EE3); at the same time, he arbitrarily extended it until the last note of the bar.

b. 281

composition: Op. 11, Concerto in E minor, Mvt III

No e in FE (→EE,GE1GE2)

e in chord in GE3

..

The added e on the 3rd quaver is a revision of GE3, both arbitrary and unjustified.

b. 281

composition: Op. 11, Concerto in E minor, Mvt III

Slur from f2 in FE (→GE,EE)

Slur from g​​​​​​​2 – our alternative suggestion

..

A comparison with analogous phrases at the beginning of this movement of the Concerto may point to an inaccuracy of the slur in the 1st half of the bar – see the note to bar 30. We include that possibility in the form of our alternative suggestion.

b. 281

b. 281-284

composition: Op. 31, Scherzo in B♭ minor

Small notes in A (→FCGE)

Regular font in FE (→EE)

..

The fact that the notes are written in normal font in FE (→EE) is a result of the engraver having misunderstood A. A similar situation can be found in b. 307-309, 383-386 & 409-411. Such mistakes can also be encountered in other Chopin's pieces, e.g. in the Mazurka in C major, Op. 24 No. 2, b. 70-88 or the Prelude in C minor, Op. 45, b. 79
