b. 121-123

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

No sign in GC (→GE) & FE1 (→FE2EE1)

 in FE3 (→FE4) & EE2

Chopin added the over two-bar-long  hairpin in the proofreading of FE3 (→FE4). It was also repeated in EE2. Similarly in bars 129-131.

It is unclear how the difference in the way of indicating crescendo in bars 127-128 occurred. The  sign could have been added by Chopin in GC, however, according to us, it can be considered an addition (enhancement) to the verbal indication. In the Chopinesque notation, a verbal indication generally indicates a global dynamic increase, generally related to a progressive harmonic sequence and often including a few bars, whereas the  hairpin generally concerns shading of the melodic line. Therefore, we also suggest a solution combining both versions of the indications, in which cresc. - - - in bars 127-128 is continued next to the  hairpin, probably in accordance with the performance intended by Chopin – see also bars 135-136.
The total absence of dynamic indications in GE1 is a patent error, corrected in GE2.

Same as in bars 121-123, the  sign was added by Chopin in the proofreading of FE3 (→FE4). It was then repeated in EE2.

GE1 overlooked the initial, falling on bar 135, fragment of the  hairpin. The mistake was corrected in GE2.

b. 153-156

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

Three-bar long  in GC (→GE)

One-bar long  in FE1 (→FE2EE)

No sign in FE3 (→FE4)

..

In the main text we include the  sign written in GC (→GE). The shorter hairpin in FE1 (→FE2EE) is probably inaccurate; its removal in FE3 (→FE4) also seems to be a mistake – crescendo is so natural here due to the quickly ascending progression and accumulation of harmonies due to pedalling. See also bars 158-160.
