Pitch

b. 146

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

..

In A (→GEFE) there is no  raising d2 to d2. The patent inaccuracy was corrected in EE, adding also a cautionary  before c2.

b. 148

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

..

In the majority of the sources, the  raising d2 to dis not before the note but 7 notes earlier, before dwritten at the same pitch, which in that time was generally considered to be enough. Strictly speaking, the sign is not necessary there at all, since dwritten at the pitch of dis already on the 4th note of the roulade – this observation most probably made the reviser of GE2 remove the sign before the second d3.

b. 151-153

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

..

In A the only  raising d to d appears in the 1st half of bar 153. Five out of seven necessary signs were added already in GE1 (only two naturals before din bars 152-153 were overlooked), which, taking into account the clarity of the situation, possibly did not require Chopin's participation (although it could have been also him that noticed the missing signs). EE and GE2 have the correct text.

b. 154-155

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

..

In A there is not a single  raising d to d. Four out of six necessary signs – only both naturals before d2 were overlooked – were added already in GE1 (→FE), which could have been performed by the reviser. EE and GE2 have the correct text.

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.
