b. 146

composition: Op. 12, Variations in B♭ major

No mark in FE (→GE)

Wedge in EE

..

To the main text we adopt the EE variant, considering the absence of the 3rd wedge in FE to be an oversight, after comparing it with bar 145.

b. 146

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

Slur to 5th quaver in A, literal reading

Slur to 8th quaver in GE (→FE,EE,IE)

Slur to 7th quaver suggested by the editors

..

As was the case 2 bars ago, one can be certain that the A slur is inaccurate, hence in the main text we suggest a slur whose range results from the comparison of analogous figures. The longer slur of the editions can be considered an equal variant.

b. 146-147

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

..

In each of these bars, A does not contain accidentals to the last L.H. chord. Chopin also omitted the  to the last quaver in bar 147. All these inaccuracies were corrected in GE (→FE,IE), while in EE the accidentals are only in bar 147.

b. 146

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

Wedge & dot in A

2 dots in GE (→FE,IE) & EE2

No marks in EE1

..

Viewed in isolation, the staccato mark over the e crotchet visible in A could be considered a dot or a wedge. The unambiguous wedges next to the three following bass notes provide a clear argument for a wedge also in this place. In GE (→FE,IE) the mark was adjusted to the dot over the chord on the 4th crotchet of this bar.
The absence of the marks in EE1 is due to the engraver's mistake, corrected in EE2.

Additional crotchet in sources

Additional tied quaver suggested by editors

..

In the main text, we change, by way of exception, the notation of the tied f quaver in bar 146. The version with a crotchet is typical of Chopin; he would often write down such notes with the help of an additional rhythmic value exceeding the scope of a bar (e.g. at the beginning of the Etude in A, Op. 10 No. 10). In this case, the need to hold this f note to the next bar, which becomes the bass note of the next chord, can be easily overlooked in the original version.
