b. 154

composition: Op. 38, Ballade in F major

e3-c3 in A (→EE) & FE2 (→FE3)

e2-c2 in GC (→GE) & FE1

..

As a result of misinterpretation of the octave sign, GC (→GE) and FE1 erroneously notate the first two semiquavers of the 2nd half of the bar an octave higher – e3-c3 instead of e2-c2. The error was corrected in FE2 (→FE3), most probably by Chopin.

b. 154-156

composition: Op. 35, Sonata in B♭ minor, Mvt II

2 dots in GC

No marks in FE (→EE)

Dot in bar 154 in GE

..

The missing staccato dots in FE (→EE) seem to be an oversight of the engraver. The second dot in GC (in bar 156) blends into the  mistake, which explains its absence in GE.

b. 154

composition: Op. 35, Sonata in B♭ minor, Mvt II

..

FE1 features at the beginning of the bar, which is a mistake.

b. 154-158

composition: Op. 64 No 2, Waltz in C♯ minor

Fingering written into FES

No teaching fingering

..

The five-time use of the 1st finger, marked in FES certainly on the basis of Chopin's hint, is included by us in the main text in bars 26-30 (cf. General Editorial Principlesp. 17).

Long accent in A

Short accent in GE (→FE)
