b. 156-158

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

1 slur in A

2 slurs in GE1

1 slur in FE (→EE)

2 slurs in GE2

..

In the main text, we give the slurs in the L.H. in bars 156 and 158 after A. The half-bar slurs of GE1 (spanning 4 and 3 quavers) are a characteristic arbitrary decision of this edition. In the proofreading of FE (→EE), Chopin combined the slurs within the bars, leaving – as probably less striking – an inaccurately marked starting point of the slurs. GE2 corrected the starting point after A, but not the divisions.

b. 156

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

..

In A Chopin overlooked some of the necessary accidentals: naturals before dd2 and a. The first and third of these patent inaccuracies were corrected already in GE1 (→FE); the fully correct text is in EE and GE2. In the main text we also add a cautionary  before bat the beginning of the bar.

b. 156-160

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

6 staccato dots in A

No marks in GE1 (→FEEE)

3 dots in GE2

..

The missing staccato dots next to the bass notes in bars 156 and 158-160 are certainly an oversight of the engraver of GE1 (→FEEE) – the signs in A are very small and sometimes put quite far from the notes. GE2 added dots only in bars 156 and 159.

b. 157

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

F in A & GE2

D in GE1 (→FEEE)

..

The quaver, present in A, is probably the original version – cf. the ascending sequence of bass in analogous bars in the recapitulation (bars 301, 303 and 305). In the main text we give introduced most probably by Chopin in the proofreading of GE1 (→FEEE) and analogous to preceding bars 151, 153 and 155.

..

In A (→GE1FE) there are no accidentals in the 2nd half of the bar. The necessary naturals were added in EE and GE2.
