Verbal indications

b. 55

composition: WN 17, Polonaise in B♭ major

No marking in JC & EF

 in PE

..

 indication in PE is probably authentic, however, it is not certain whether Chopin's intentions were correctly identified, as far as its position is concerned. It cannot be excluded that the piano dynamics is supposed to concern the entire bar.

b. 60

composition: WN 17, Polonaise in B♭ major

No marking in JC & PE

in EF

The indication  is only in EF. Its authenticity becomes a problem if we take into consideration the indications cresc. and  in bars 61-62 in PE, which undoubtedly come from the autograph. According to us, those and previous dynamic indications of PE suggest only a local climax in the described place and a return to the dynamics from the beginning of the Trio (), to sum up, an effect which can be marked with the indication

b. 62

composition: WN 17, Polonaise in B♭ major

No indications in JC

più  in EF

 in PE

..

The indication più  in EF is probably non-authentic, same as  which precedes it in bar 60. It is worth mentioning that despite the fact that the dynamic relation defined with those indications could be generally assumed as compatible with cresc. and  in PE, the overall impression is totally different: the notation of PE is more precise in details (crescendos in bars 59 and 61), at the same time, it leaves more freedom by not determining the dynamics in bar 60; it also indicates the climax ( in bar 62) more clearly.
