b. 148-149

composition: (Op. 4), Sonata in C minor, Mvt IV

..

In A a few accidentals are missing to the notes that were already altered in other octaves – the flats to g1g2g in bar 148 and the naturals to A and a1 in bar 149. The accidentals were added in GE (→FE,EE,IE).
In the main text we omit the  to A at the beginning of bar 149, present in all sources. GE (→FE,EE,IE) also added a  to a.

Long accents in A

 in GE (→FE,EE,IE)

..

In A the  marks in these bars are half the length of the one in bar 147 and are definitely long accents. In GE (→FE,EE,IE) they were considered identical with the mark in bar 147, which, according to us, does not comply with Chopin's intention.

g1(2) & g2 in sources

g1(2) & g2 suggested by the editors

..

The absence of the flats lowering g2(1) to g2(1) at the beginning of the 2nd half of the bar (or at least one of them, as Chopin would often settle for one accidental for a few notes of the same name placed in different octaves) is almost certainly Chopin's mistake. This is indicated by the comparison with bar 146, of which the discussed bar is a variational repetition, and in which g notes are certainly absent. At the same time, this is not a temporary coincidence, since the entire four-bar section (bars 150-153) is, harmonically speaking, a repetition of bars 146-149, kept in the key of E minor.

Slur in A, literal reading

Slur in A (contex­tual interpretationGEEE,IE)

Slur in FE

..

The ending of the A slur in bar 153 must be inaccurate. To the main text we adopt the GE interpretation thereof (→EE,IE). The later starting point of the slur in FE is most probably a mistake by the engraver. This slur, together with the one in bar 150, undoubtedly means that the entire quaver sequence should be performed continuously legato, as in similar contexts the division of slurs falling on strong beats was often considered irrelevant.
