b. 218-219

composition: Op. 35, Sonata in B♭ minor, Mvt I

..

GC includes identical sets of accidentals in the last chord in the R.H. in bar 218 and the first one in bar 219 – a  before the top bottom note (d2) and a  raising g2 to g2. In GE1, the  in bar 218 was printed before e2, which has to be considered to be a mistake, as the sign before dwas placed correctly, whereas the  before eshould have been already in the previous chord. In GE2 it was noticed that in bar 219 the  is supposed to concern the adjacent note, e2, however, the erroneous notation of bar 218 was left unchanged. FE (→EE) include the correct notation.

It is worth observing that in GC and FE the  before gin the last chord in bar 218 is not unnecessary, as the sign is absent in the previous crotchet.

In the main text, we add a cautionary  before din bar 218.

No bottom g1 is certainly an oversight of the engraver of FE (→EE).

We give the  indication exactly after A. It indicates, together with the slur embracing the octave leap, that the variant of the initial motif of this movement of the Concerto should be played distinctly. The detail was inaccurately reproduced in the editions. Similarly in bar 220.

In EE and GE2 the accent was reproduced as short. See the previous note.

sempre legato in FE (→EE)

..

Chopin added the sempre legato indication in the proofreading of FE1 (→FE2EE). It certainly concerns the L.H., which is devoid of slurs from that place on. While writing A, Chopin would perhaps think that the slur in bar 217 would be enough (as an example to follow in subsequent figures); however, upon seeing this place during the proofreading of FE1, he considered a clearer indication of the performance manner to be necessary – this is most probably the so-called harmonic legato, i.e. holding elements of a chord with fingers, which is partially written with rhythmic values.
