b. 145-146

composition: Op. 21, Concerto in F minor, Mvt I

2 staccato dots in A

No marks in GE1 (→FEEE)

1 dot in GE2

..

The overlooked staccato dots over in bar 145 and A in bar 146 are certainly a mistake of GE1 (→FEEE). GE2 added only the dot in bar 145.

b. 145

composition: Op. 21, Concerto in F minor, Mvt I

 before 5th quaver in A

 before 3rd quaver in GE (→FEEE)

..

The too early placed  sign is undoubtedly an inaccuracy of GE (→FEEE), undermining the dramatic effect of the dynamically exposed phrase (con forza).

b. 145-160

composition: Op. 21, Concerto in F minor, Mvt III

No L.H. slurs in A (→GE1FE)

L.H. slurs in EE

L.H. slurs in GE2

..

In the entire section, Chopin wrote only one slur in the part of the L.H. in A, in bar 146. The fact that he then resigned from repeating the slurs written in the R.H. is proved by the notation of bar 160, opening a new page in A: in the part of the L.H. one can see there a deletion of a slur reaching the a minim and suggesting continuation from the previous bar. Therefore, the decision to add slurs, which were introduced in the entire section in EE (apart from bar 157) and GE2, was arbitrary, and it almost certainly does not correspond to Chopin's intention. Moreover, the added slurs differ between EE and GE2, since each of them copied the slurs of the R.H., which in EE generally correspond to the slurs of GE1, whereas in GE2 – to the slurs of A (cf. bars 152156157-158 and 159).
In the main text we preserve the notation of A. We discuss more complex situations from the point of view of sources in bars 146-148148 and 154 and 151 separately.

b. 145-146

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

Slur in FE (literal reading→GE1GE2)

Slur in FE, possible interpretation

Tie to  f1 in EE & GE3

..

In the main text, we give the interpretation of the curved line of FE (→GE1GE2) adopted in EE and GE3. The Chopinesque manner of writing ties as short curved lines reaching the prolonging note would frequently result in their erroneous interpretation. However, other possibilities cannot be excluded – the curved line in the autograph could have been led over the top voice, since moving slurs to the side of note heads was a routine procedure, frequently applied by engravers.

b. 145-146

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

..

Due to a possible misunderstanding of the Chopinesque tie sustaining f1, in some sources the note is repeated – see the previous note.
