b. 98

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

Quavers in A & EE1

Crotchets a & f1 in GE (→FE) & EE2 (→EE3)

4 crotchets alternatively suggested by the editors

..

The stems extending a and fon the 1st and 4th crotchets in the bar were added in the proofreading of GE (→FE), most probably by Chopin, since there is no reason to make a mistake. As one cannot exclude that the proofreading was implemented inaccurately, we alternatively suggest extending also the two remaining bass notes.

b. 98

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

No c2 in A & GE2

c2 in GE1

c2 tied in FE (→EE)

..

An additional cnote could have been added by Chopin in the proofreading of GE1 (→FEEE). The melodic line of the accompaniment, where the second quaver of each pair is higher than the previous dyad or chord, suggests that the note was probably to be sustained, which was then performed in the proofreading of FE (→EE). It cannot be excluded that the additional cwas printed in GE1 by mistake and left unnecessarily after having added the correct note, a(a Terzverschreibung error). The tie of this note, added in the proofreading of FE (→EE) and eliminating its repetition, would be then a "simplified correction," which would happen in Chopin's works, e.g. in the Polonaise in C minor, Op. 40 No. 2, bar 125. GE2 restored the version of A.

In the main text we give the version of FE as intended or accepted by Chopin. The version of A may be considered an equal variant, whereas the version of GE1 is almost certainly erroneous.

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

The sign added in FED over the g2-d3 quaver probably means staccato, which is indicated by the vertical line separating this quaver from the next semiquaver. The sign looks like a wedge, however, one has to remember that Chopin teaching entries are often careless and they usually deviate from the standard forms of signs. Moreover, the line, doubling the function of the rest, proves that the aim of the entries was most probably a correction of an erroneous performance; in addition, this kind of corrective entries are sometimes exaggerated. Due to this reason, in the main text we suggest a milder version of staccato.

b. 99

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

 after d1 in A (→GE)

 under d1 in FE

 before d1 in EE

No sign in GE1a

..

The  sign was reproduced inaccurately both in FE and EE, each time shortening the ordered time of holding the pedal.

In some of the copies of GE1a, graphic retouches aimed probably at eliminating defects around the slur in bars 102-103 were performed (the defects are visible on the copy presented in our system). While performing corrections, the  sign discussed in bar 99 was deleted by mistake.

b. 99-100

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

..

In these bars, in the part of the R.H. A has only one  raising d to d – at the beginning of bar 99. The  returning bat the beginning of the septuplet in bar 100 is also missing (all previous figures are delayed at the beginning of the group, a suspicion of Chopin's mistake is confirmed by the  written in FED). The editions added both necessary and cautionary signs; superfluous signs were deleted too, yet none of the editions has the completely correct text. In the main text we give all signs necessary for the correct determination of the pitch and two cautionary flats at the beginning of bar 100.
