b. 145

composition: Op. 23, Ballade in G minor

Chord in A

Rest in FE (→GE,EE)

..

The chord on the 2nd crotchet of the bar was removed at the stage of proofreading FE (→GE,EE), along with the accent and the slur, undoubtedly at Chopin's request. Traces of removal of the aforementioned elements are clearly visible in the subsequent copies of FE.

b. 146

composition: Op. 24 No. 4, Mazurka in B♭ minor

Accents in A

GE1 and EE

FE and GE2 (→GE3)

..

The two accents were clearly written in A as a short one and a long one. In GE1 that difference was disregarded and two short accents were put in. That version was revised in GE2 (→GE3) by lengthening the first accent (against A). FE also presents a similar version, which was changed to two equally short accents again in EE (following the general tendency of that edition).

b. 146

composition: Op. 24 No. 4, Mazurka in B♭ minor

No pause in A (→GE1FEEE)

A pause in GE2 (→GE3)

..

In GE2 (→GE3) a pause sign, obvious in this context, was added over the rest in the L.H. part. Making the notation more specific in that manner is advised in the scores of works for more than one performer, but in piano music it is not necessary.

composition: Op. 64 No 3, Waltz in A♭ major

..
