b. 306-307

composition: Op. 2, Variations, complete

cre - scen - do in A

cresc. in GE (→FE,EE)

..

In the main text we roughly reproduce the notation of A, in which crescendo is written out as a full word, divided between two bars (without dashes). The part of the indication falling on bar 307 was left out in the editions, probably due to the transition to a new page (both in A and in the editions), which, however, does not generally influence its meaning, yet it is less suggestive.
The editions also left out the  hairpin – see bar 112.

b. 306

composition: Op. 2, Variations, complete

 on first chord in A

after first chord in GE (→FE,EE)

..

It is uncertain what led to the difference in the position of the  indication. It is unlikely that we could be dealing with Chopinesque proofreading of GE1; moreover, there are no traces of the indication having been moved in print. However, the interpretation of this mark makes us consider the version of the editions to be more accurate. In A the mark is also written in the solo part, although repeating it only for its last chord does not seem intentional. Therefore, according to Chopin,  must have referred to the connecting passage marked as Tutti as well, which is confirmed by the full version of the Variations – the orchestral Tutti starts already at the beginning of the bar, whereby  marks are written in the parts of wind instruments at the beginning of the bar, and in the ones of string instruments – on the 2nd quaver. When copying  probably from the parts of the wind group, Chopin did not notice a possible ambiguity resulting from the lack of synchronisation of this indication with the beginning of the Tutti, which in the version for one piano is marked only just on the 2nd quaver in the bar.

b. 306-310

composition: Op. 49, Fantaisie in F minor

sempre più mosso - - in A

No indication in FE (→EE1)

sempre più mosso in EE2

As was the case with stretto in bar 290 and più mosso in bar 294, sempre più mosso was also a later Chopinesque addition to A (→GE). On the basis of GE1, it was also added by EE2. None of these editions reproduced the dashes marking the range of the indication correctly – in GE they were led a bar too far, whereas in EE2 they were overlooked.

b. 306

composition: Op. 49, Fantaisie in F minor

..

In FE1 the middle note of the penultimate R.H. chord is an erroneous d2 instead of e2. The mistake was rectified in FE2 (→EE).

b. 306-310

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

Crotchet a in A

No crotchet a in GE (→FE,EE,IE)

..

In bar 306 and 310 the omission of the fragment of the crotchet stem attaching a on the last crotchet of the bar to the R.H. part was an arbitrary simplification of notation performed by the GE engraver.
