b. 157-158

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

a1 repeated in A (→GE1FE)

a1 tied in EE & GE2

..

The missing tie of ais almost certainly a mistake of Chopin, who did not introduce the changes performed in the R.H. to the L.H. It seems that a1(2) at the beginning of bar 158 was to be originally repeated – the crotchet in the part of the R.H. was even provided with a staccato dot, deleted then probably when a tie was added. This scenario is confirmed also by the dots over the crotchets at the end of bar 157 – see the note dedicated to them. A tie was added in EE and GE2.

b. 157

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

Staccato in both hands in A

R.H. staccato in GE1 (→FEEE)

No marks in GE2

..

Staccato marked in A over the last crotchet in the parts of both hands is, according to us, a remaining element of the original version, in which the notes were not tied – cf. the note on the tie in the L.H. Therefore, we omit these dots in the main text. In GE1 (→FEEE) the dot of the L.H. was omitted, which must be an oversight, since two previous dots were also overlooked. In turn, the absence of both dots in GE2 is a revision, probably based on a reasoning similar to ours.

b. 157

composition: Op. 22, Polonaise

..

The only cautionary accidental in FE (→GE1GE2) is the  before a3. EE added a  before a2 in the L.H., while GE3 naturals before c2 and c4. In the main text we include all these accidentals.
