b. 172

composition: (Op. 4), Sonata in C minor, Mvt IV

energico between staves in A

energico below L.H. part in GE (→EE,IE)

No indication in FE

..

A look at the dense GE1 notation allows us to say that the energico indication was placed in GE (→EE,IE) under the L.H. part only due to the lack of space between the staves. In FE the indication was omitted, probably due to inadvertence.

b. 172-173

composition: (Op. 4), Sonata in C minor, Mvt IV

into b. 173 in A

in b. 172 after GE (→FE,EE,IE)

..

The change of the range of the  hairpin in GE (→FE,EE,IE) was partially forced by the lack of space for extending the mark in bar 173. In the main text we adhere to the range written by Chopin in A.

b. 173-174

composition: Op. 39, Scherzo in C♯ minor

GC (→GE) & FE

The version of EE is probably erroneous, both as regards the chord in bar 173 and the division into two hands in bar 174.

b. 173

composition: Op. 42, Waltz in A♭ major

d1-e1 in FE (→FEGGE1)

d1-e1-g1 in EE & GE2 (→GE3)

..

The d1-e1 second featured in FE and GE1 is the original version, which is proven by the comparison with the remaining four analogous places in bars 49, 81, 113 and 269. In three out of five places Chopin added to it a gnote in FEG (→GE). In EE the completed version with the d1-e1-g1 chord is in all five places, which also proves Chopin's proofreading. Therefore, the fact of leaving the original version of the discussed bar in FE and GE1 must be considered as Chopin's oversight.

b. 173

d2 in A (→GC,FE,EE)

d1 with  suggested by the editors

..

As in bar 169, next to the bottom note of the 1st sixth in the 2nd half of the bar there is no accidental neither in A nor in GC and FE, which were proofread by Chopin. Therefore, we should accept this note to be d2, and that is what we give in the main text, supplemented with a cautionary
